Never attempted repairing car, but managed to do this with the help of this video! Amazing, thanks for sharing your knowledge… car is now happy again 😊

[@seanpburke]

You are a legend - thank you so much for this, I’d been to multiple garages who would only change out the full system. I’ve done 100km since doing this and it’s back to normal - took some time to find the right level but all good now. Thanks again.

Epic video, car went down during the day parked down. Did the nursery run with it on bump stops in town, rode like a horse cart. Came home, watched your video, ordered the solenoid on Amazon for £20. Next day I removed the compressor and the solenoid in 15 minutes, the delivery arrived that exact time, I put it together in another 15 minutes. Suspension sorted. Thanks!

Thanks for taking the time to make this video and for the clear logical steps taken to rectify the issue. Much appreciated. My F11 goes down on one side so I can now have a narrower focus on finding the fault than without your help.

Thanks Robert, I hope you get it sorted. For a so called premium brand, they are not very good are they, so many people with the same issues and no recall from BMW. I will not be buying another.

​@@magnacartalibertatum7018hi. I have the same issue.... my f11 is down on one side. Did you found the solution for this? I would really apreciate if you could share it with me as I can't really afford waisting more money on workshops who just change the wrong parts. I hope that you can write me back, Thanks

[@paulwatts1704]

Very helpful video - thanks. I completed the replacement in about 2h - a bit fiddly getting the cover off (plastic nuts that can strip easily) and the sponge soundproofing had gotten wet and dirty so needed to be cleaned and dried. The car, an F11 2013 has already had a 2 new airbags and an OEM compressor about 5 yrs ago - but yesterday the rear suspension dropped on to both bump stops whilst out on the road so I knew it wasn't the air bags leaking. Also the compressor was still running which is an obvious indicator it was the input solenoid. As I was under time pressure I simply undid the input pipe, solenoid connector and the 2 screws holding the air drier tank to the main body. I then swapped out the solenoid. Thus, there is no need to remove the whole compressor unit which makes it easier and less likely to break something else. So all fixed for £23 and 2 hours work. Changing out the whole compressor (had it not been running) would not have been much harder - you can buy reconditioned original for £160 on ebay plus £80 deposit on your old unit. So even then the job would have cost £160 not the £2000 plus a stealership would have wanted (or the £1000 a specialist charged me last time).. Thanks again for your video.

Hi Jon, had the same failure on my X5 this week, took the compressor off checked the balls in the vessel and they were soaked. Took them all out put them on an old quality street tin lid and dried them using a blow torch from a distance. Put them back in reinstalled the compressor but no change. Had already ordered the solenoid valve just in case as I didn’t want the car out of action for long, that turned up in a day or so and only cost £20, swapped it this morning started it up and boom, all working perfectly.. thanks for the vid saved me a load of cash and was surprising easy to do. Happy new year fella.

Looking on BMW forums they all seem to be pointing at new bags even though the issue is intermittent and both sides. I'll order a new valve now. Can't thank you enough for sharing this.

[@christianyde9847]

Thanks for a great video with a very good and detailed explanation of the system 👍 I had my 520d 2013 up on the lift and was just about to replace the airbags, when i came across your video, and realized that it more likely was the solenoide that was broken. My BMW was also sitting on the ground, and when it was started the compressor would start for a few seconds, without anything happening. I took the solenoide off and found out that it was in the closed position which it should be. When i checked the resistance of the two pins of the solenoide the resistance was 12,8 ohm, which seemed pretty normal. I then connected the two pins of the solenoide to a 12V battery but it remained in the closed position, until i did connect it maybe 20 times and then it suddenly started to work, and i could now blow air through the solenoide when it was connected to 12V. I then assembled it again and the car worked perfect and still does, and i could even return the unused airbags 😊

[@gregmcfc82]

very helpful video my BMW 520 2017 M3 sport has yesterday developed this issue, and they have diagnosed it to be the compressor and they have come back with a total cost of around £1,100 including labour and VAT but its still a big kick in the stomach for a Friday afternoon 😮 and it least i will get a good warranty with a genuine bmw part

[@cwillis139]

Very useful video, thank you! Saved me a ton of time and money figuring this out for myself.

[@garywilliams9602]

Enjoyed the video this morning. Excellent fault diagnosis Jon. I too have been working on the air suspension this weekend on my Range Rover when it dropped to its bump stops. Mine was a worn compressor piston seal. It has a very similar system to yours with compressor, valve block height sensors etc except air on all 4 corners. The air drier on mine is a replaceable part as you point out, water in the system is the main cause of problems. Keep up the good work Jon and hopefully we will see your shaper making chips soon.

[@jonsworkshop]

Hi Gary, thanks for the comment and feedback. I can see the benefits on a 4x4, but not on a motorway cruiser. Totally unnecessary in my opinion, its just a cash cow for them. On borrowed time with me, going back to a sensible car soon. Cheers, Jon

[@retromechanicalengineer]

Nice cheap fix Jon. The same system as was fitted to my Discovery, but it was the air bags that failed. You can't really blame the dealer. They have to warranty the system if they repair it and they can't do that if they've delved into the pump, so they fit a new one which is warrantied. The consumer has driven this type of activity, it's just a response to what the market wants as a whole and is an expensive business. There are few garages these days that have the time and would take the risk of breaking into a component. Best wishes, Dean.

[@jonsworkshop]

Hi Dean, thanks for the comment, agree on the consumer bit but they are ripping people off big time. This took me about an hour to do including all the strip down etc. If I was just replacing the whole unit and using ramps etc, I could do it in about 30 mins, Wabco unit is list price at £850 so even if BMW were paying list (which they won't be), that works out about £2500 hour labour rate based on what they quoted me!! They are at it! Cheers, Jon

This will be my last Beemer, not impressed with the whole package from crappy and damn expensive run flat tyres that pull the car all over the road to not being able to make it up a 10 degree incline in mild frost, to over engineered and expensive suspension...... the list goes on!

What else has such a powerful drive, is as nice looking, as luxurious & fancy inside & out & has such cool features like seats that heat & cool? Big ass sunroof? Shiny wood trim?

Hi, this video is great, I am in process of doing the same on my g31. The desiccant in mine was a bit brown with moisture and corrosion on the solenoid. Not put it all back together yet but wondering if the moisture is a sign of another problem?

[@jonsworkshop]

Hi, I am no expert or mechanic, but my gut feel is yes. Either the compressor is running overtime due to a leak somewhere meaning it is drawing more moisture in, or, you live in a very humid environment and the air drying part of the compressor isn't working properly, these are just guesses though.

[@houseofbrokendobbsthings5537]

Well BMW 5 series quite decadent - LOL. As you might guess I did a lot of this type of work. The design of the compressor is very clean and elegant. I was curious if the two solenoids on the left are the only isolation between the compressor and the bags? Or, are there additional solenoids at the bag itself? Those have to be the lowest height ramps ever created. Clearly you and my Scottish cousins must be a bit more trim than we Americans… LOL. The height trimming logic can be a sneaky thing. If the height cannot be reached on one side the code writer (Hans) may command the opposing side to lower to the failing side height. This is to maintain dynamics in the error state. Inverse is true if it can’t lower properly it may force both sides to max height (snow bank logic as it thinks you have lowered to an obstruction). Well done Jon! Hoping it behaves henceforth. 2,100 is stiff for parts. However, just wait for the carbonless generation coming up that will be an entire new level of repair cost.

[@jonsworkshop]

Hi Dan, thanks for the comment. Lol, the ramps are leveling ramps for the motorhome, not meant to be used as I did. The car was that low I couldn't get my trolley jack under. I used the ramps to get the space for the jack and realised I could just about manage the whole job on them albeit a tight squeeze. Cheers, Jon

Hi Paddy, sorry, I don't have a clue with electrics and I am not a mechanic. All I can suggest is too much current being drawn therefore replace fuse, switch on and listen to see if compressor is constantly running or labouring etc. Beyond that I have no idea. Is anything shorting out where you replaced the cable blocks? Mine has not done this so I have no experience to work from either.

[@jonsworkshop]

If the beads are damp, I would advise drying them while you have the thing apart. Microwave in a glass dish until they go back to light colour. Damp beads are a symptom of another problem, either your compressor is running far too much which could be an air leak, or you live in a very damp or humid environment.

[@rchwha]

[@matttaylor2008]

@@jonsworkshop Hello. Just been scanning through these comments after watching the video and completing this fix about 2/3 weeks ago. Very helpful video thank you. I checked the beads but only briefly and I'm thinking they could be causing a further problem. The solenoid fix worked perfectly but since then the car drops over 3/4 days then when the compressor kicks in it blows the fuse. Think this points to an overworked compressor? I thought the slow dropping might be down to me not putting it all back together properly.

[@derekscott5708]

Hi Jon, great video and analysis . I used it to hep changing the dump solenoid on my F11 this morning. For the past 6 months I have had an intermittent fault with the car sitting down on its haunches. More obvious and immediate on the offside. Sometimes this happens within 10 minutes after switch off, sometimes it will hold pressure for a week. Once down , the car won’t rise up completely on start up on the first journey but after I stop and start the car again it does. Anyway, changing the solenoid made no difference. I have replacement airbags on standby but based on the intermittent nature of the problem I am of the opinion they are not at fault. What do you think? Perhaps the individual solenoids where the red/ blue pipes connect?

[@jonsworkshop]

I am no expert so just guessing here, as it is intermittent it has to be either the double valve unit or an electrical fault, for what it costs it is worth a gamble on the valve block. If it was bags leaking it would be consistent. Let us know what you do and what results you get, many others on here with the same fault. Cheers, Jon

[@derekscott5708]

Hi Jon Thanks for responding. Straight forward mechanics I can do but I was never any good at diagnosing electrical faults. With that in mind I was thinking the same thing, change the valve block. Although the double block feeds air to each bag individually I just wasn’t sure it allowed air to drain back . I can get a good one for around the £50 mark. I am currently in France, so getting one mailed over isn’t always simple but I will post on here when the job is done.

[@derekscott5708]

@@jonsworkshop Hi John, finally got a replacement control block which controls air to both bags and installed this last week. Unfortunately it has made no difference. No great expense, £25 for the control valve and £25 for the dump solenoid, just a pity they didn’t work. The desiccant beads did need drying out but this too hasn’t really made a difference. It is strange as the car will work as normal then perhaps 1 day in 3 the rear end lowers. This can take either 30 minutes or overnight. Once down it does not raise ( other than an initial charging up /priming of the compressor) . After a short drive and switching off the ignition, the car returns to normal and raises up on second start up. Possibly an electrical fault or load sensor fault - who knows?

Finally cured the problem by replacing the suspension airbags. Despite the intermittent nature of the collapsing I decided to give changing the bags a go and Bingo.

My local mechanic changed the balloons. Didn't help so he changed the compressor ,motor with solenoid. They solved the issue. Last combined valve was not changed. My old compressor is working but pressure is inadequate. No water in air chamber, piston ring is ok and solenoid is not leaking air. What else could be wrong?

[@jonsworkshop]

Hi Arun, I am not a mechanic (disclaimer) but based on your description, either the motor is running slow on the compressor (don't know how you could check that easily) or you have a leak somewhere. The compressor housing could have a crack in it, as could the cylinder head, or one of the joints etc. Best I can suggest is switch it on and spray leak detector all over the unit (or brush on a dilution of washing up liquid) and see if you can spot any air leaks. Failing that, real close examination of the piston ring or bore for scratches/damage, it wouldn't take much damage to lose efficiency on such a small compressor. Cheers, Jon

Hi, I really am no mechanic or electrician.

[@TimothySmith-o6e]

Jon, great insight, just about to purchase a 2012 5 series tourer, 55k miles & hasn't towed, the current owner mentioned that a prospective buyer declined to purchase because the air suspension hadn't in fact been replaced, although it is working fine. What age is your BMW?

[@jonsworkshop]

Mine was a 2017, was being the operative word. Best thing I did getting rid of it. If you want my advice, buy a Skoda Octavia estate instead. BMW have lost their way totally, getting caught up in the "how much expensive technology can we cram onto one vehicle" nonsense so they can make back the money they lose at initial sale as quickly as possible. I will never own another now. Good luck if you take the plunge, make sure you have plenty of spare cash for the upkeep if you rely on it for work.

[@renekirsel]

I replaced the solenoid valve and everything seemed to be good, rear end lifted up. Then I started getting same chassis faults, but rear end was up and good. With diagnostics I found out, that now my compressor can only lift rear end and not lower anymore. Do You think the new solenoid valve could be responsible for that? That the old one was stuck open and new one is stuck closed?

[@jonsworkshop]

Hi, thanks for the comment. I have no idea as I didn't get that fault, sorry. It could be a dodgy valve maybe, if you still have the old one you could try swapping them back and see if the original fault returns. Check you haven't blocked or crimped any pipework. Apply 12v to the new valve and see if you get any movement or noise. When you apply voltage, can you blow through it etc. Can't think of anything else.

[@magnacartalibertatum7018]

My f11 is sitting lower on the drivers side. Any ideas on that? Could it be an air bag or compressor? Cheers

[@Marco-jy9ju]

Should i do this also? Because only my left rear side is down, and when i turn my car on, the compressor wont turn on

[@jonsworkshop]

I am not a mechanic and only have experience of the error I had, however, if it's only one side then it's a different problem so changing the same valve won't fix it unfortunately. Get the airbag checked first on the bad side would be my advice.

Hi Jon! My bmw 730D 2016 has same issue one side went down. live in Glasgow. wondering if there is any way to contact you directly. Many Thanks

[@hansfreekit]

Mine was up and down - both sides - intermittently. So I had a go and found the dessicant waterlogged. Replaced the solenoid with Amazon new one also. Put back together and fitted back on. Except when I turned the ignition on.. Nothing. No sound from the compressor. just an error on the dash computer. I wired it up right I think. I'm not very electrically minded but now I'm scratching my head.

[@davidhoban9919]

Can the solonoid be swapped without removing the compressor from the car? I just changed my airbags and it's still dropping overnight.

[@jonsworkshop]

Hi David, thanks for the comment and question. I would probably say no (trying to remember, but I think access is too restricted). Once you are in under the car, it's only 4 screws to drop the whole unit out so much easier to attack this on a bench would be my advice. Cheers, Jon

[@markhughes3387]

Thanks so much for this Jon. Just about to attempt the repair myself. I've seen some talk of having to bleed the system. Did you find that?

Hi Greg, no, mine was completely down with no pressure at all in the system. That is a good point though, just carefully undo the blue, red and feed pipes and be aware that the car will drop if you are underneath it. Cheers, Jon

[@gdstruthers]

@@jonsworkshop thanks a lot Jon. Took less than an hour all in. Hardest part was locating the bolts to remove the plastic housing/ under tray. I had a sporadic issue with coming out and finding the car on the bump stops. Upon removing the solenoid found a ring seal wasn’t sitting where it should. All refitted and system seemed to inflate with no need to bleed. Garage quoted £600, repaired after watching your video for less than £25. Thanks again.

[@joandar1]

Great informative Video Jon!! I learned a lot from this expose! I have a Wabco air compressor that came from my Brothers BMW powered Land Rover and wondered about various aspects of it. It works fine by the way, he took out the air bag and put coils in his Discovery as a better option. I was given the pump and turned into an air compressor for pumping up the tires on my Nissan Patrol. I put in an Ally box with a pressure tank and and made a fitting so that I could dump all the air from the tank in a split second to be able to re-seat the beads back on the rim should that happen when I was going or coming back from Beach Fishing. I also did some homework on Wabco and found that they have or perhaps had a large Manufacturing Plant in CHINA. Makes me wonder about BMW's price justification!? PS: A good use for one of these pumps if you can lay your hands on one for less than 2100 or 550! Just need a few tools and have a think. John, Australia.

[@jonsworkshop]

Hi John, thanks for the comment. Standard coil over shock would be a shed load more reliable and much cheaper to replace. If the worst comes to the worst and I have to end up replacing the whole unit, guess where the old one is going lol. Cheers, Jon

[@djjjh277]

How do you remove this unit ?

[@icemancool5136]

Thanks Jon, very informative video. The BMW guys are probably not very keen on someone like you sharing this hack. I have the same BMW F11 and I have already replaced both spring airbags and new compressor over 2 years ago (all have failed). Recently I’ve been getting a message on the dashboard saying “Chassis Function Restricted” and it looks like the suspension is stuck in fully up position making the ride uncomfortable above 60-70 mph. Do you think the same discharge valve could be responsible for this scenario?

[@jonsworkshop]

Hi, in terms of the BMW guys, I couldn't care less, if they don't want bad press, don't sell prestige brands with inherent faults they are unwilling to formally address. In terms of your error, I really wouldn't know as it is a different fault to the one I had. As the dump valve is responsible for letting excess air out the system, it could well be stuck in the closed position so for £25 it is worth a gamble. It could equally be an electrical or plc issue though. Cheers, Jon

[@tomladdus9264]

I just finished replacing the airbags on my 2012 X5 thought that would do the trick, it seems to have helped a little, in that now the suspension is not slamming when I go over a small bump, however, it is still a rough ride and the level still seems low. The thing you observed in your video is that both sides went out together, that seems to be the case on mine too, if it were one of the airbags then they would have failed separately, but both sides are low. It seems that my situation is similar would you agree? I am a car mechanic noob, so just want to know how hard it is to get the compressor out and what part did you order? I've got a jack and jack stands, from the airbag replacement so hopefully won't need much more.

[@jonsworkshop]

Hi Tom, I am no mechanic lol, easy to get the compressor out, a few screws and clips to remove the plastic trims etc, then 4 screws, two electrical connections and two air hoses, 20 mins tops. Based on your description it could be similar. Certainly not much to lose trying, if it doesn't work you will only have lost a few ££ and a couple of hours etc. Cheers, Jon

[@tomladdus9264]

@@jonsworkshop thanks took it out, feeling pretty manly, hahaha. I then took apart compressor. It was full of water, black goo, brown gunk, and signs that it was quite unhealthy. I cleaned it out and dried the interior, reassembled it. Was getting ready to test it. But decided that I would just order a replacement unit aftermarket. This one has 140000 miles on it. If I get it working, I can repurpose it as a standalone compressor. After cleaning it doesn’t look too bad but worried there may be some hidden issue.

[@jonsworkshop]

Hi, it did, but with all the plastic coverings in place that conceal the unit, you can't hear it running over the engine noise. The only way to know is to remove all the coverings, you will definitely be able to hear it then if it's running. Cheers, Jon

@@TheWhizzey no bother, sounds like a siezed piston, or motor maybe on the comp unit.

[@IanColclough]

My air suspension goes down periodically on the passenger side. As it is intermittent what do you think is the most likely fault - leaking solenoid?

[@jonsworkshop]

Hi Ian, thanks for the comment. I really don't know in that situation but my guess would be, if it is intermittent then probably not the airbag itself. There is a solenoid for each side (the other unit I didn't replace on the compressor), what I don't know is if there are any more solenoids at the airbag itself, if there are then it could be that. If its electronic (system, computer, logic etc) then I am totally lost as I don't understand that stuff. Sorry not much help. Cheers, Jon

[@TrinityCT11]

Hi Jon. Great video, but wondering if you can offer any advice as my issue is slightly different. So I started to notice my near side dropping right down, the offside dropped a little, but not nearly as much, so assumed it was just being dragged down as a consequence of the NS. Anyway, I replaced both air bags at the same time, but still happening :( Was fine for the first 5 days, but the NS went completely down overnight. It pumps up really quickly again when the engine is on. Could it be one of the smaller solenoids you mentioned? Got a part number\link for those?

[@TrinityCT11]

Been doing some further research and looks like you can change the valve block for £20, but to help diagnose, I'm going to swap the blue and red tubing over, see if the OS dops instead, then I'll know that's the faulty component.

[@jonsworkshop]

@@TrinityCT11 hi, no idea but your investigation idea is superb. If you have changed the bags then it can only really be the twin solenoid block (or it could be a pin hole or leak in one of the lines don't forget). Please post your results here, this video is getting a lot of traffic so you may help others out. Thanks. Jon

Hi guys. Anyone know what it means when there is moisture in the decant. I opened mine but in the video the beads were clear and it did not have the problem I have. The beads are all brown and stuck together. Any fixes guys? Thanks

[@jonsworkshop]

Hi Bilal, I am no expert but it basically means your compressor is working too hard which probably means you have an air leak somewhere else. You can regenerate the media by pouring the beads onto a baking tray and putting in the oven at 100 C for about 45 mins. Dry the housing out with cloths and then reassemble. You also need to dry the filter papers (hair dryer should do it). Like I said, you will not have got to the root cause but this will get you going again in the meantime. Cheers, Jon

[@624Dudley]

Good for you, Jon! That sort of fault is much more diagnosis-friendly than a problem somewhere within an inscrutable electronic control module. Now, in your opinion, is that driver-adjustable suspension system worth having? I’ve never owned one, and it seems like a lot of potential trouble.

[@jonsworkshop]

Hi Dudley, thanks for the comment. Short answer, No! Total waste of money, I think the whole thing is designed to draw people in dazzled by the amazing technology (and to make an absolute killing on spares by fitting un-serviceable parts as standard). I can't say I notice any real benefits. They probably have to fit it to soften out the crappy hard ride that comes from the stupid run flat tyres they put on as standard. You can probably tell I am completely underwhelmed by this car, not worth the ticket price! Cheers, Jon

[@ar4732]

Just to add, for any car it's worth having a decent OBD reader. In the case of BMWs, it's worth getting a copy of ESys & ISTA + cable which allows you read any code and reset/adjust etc. Obviously it's only worth it if you plan on keeping the car for a decent length of time. Great video Jon - going through the same fix and waiting for the part to arrive. It's amazing and sad how few people are willing to get their hand dirty on their car or around the house.

Hi Jon I have an issue with mine but it’s only the right side any idea what you think the issue maybe.

Hi Jamie, I am no mechanic or expert but if its one side only I would suggest it's either the airbag or solenoid valve (in the double unit I didn't change). If the right side pumps up and is intermittent then start with the valve, if it is repeatable every time going down in the same time frame it's probably the bag. I repeat, I am only guessing as not a mechanic. Cheers, Jon

Try swapping the red and blue lines, see if the error moves to the other side, this will eliminate the airbag
