Hi Dan, I know it’s been five months since this video but we got a 2015 X5 (f15) in the shop today for low rear suspension. I knew it was coming in and watched you vid to become more knowledgeable. The vent vent on this car leaks down on random occasions. I’ve used the link in this message but can’t find a vent valve listed. ( or the desiccant refill) Hate to replace a working compressor and solenoid valve when they’re fine. Help! Doug

Start using mechanics not fitters.

[@Uninfluenceable]

FYI, for any of you DIY'ers, you can buy a new vent valve for $40 USD from AliExpress, that is really one the most common parts that fails on these new style Wabco pumps. The soft flexible membrane piston rings last much longer on these than the old plastic styles piston rings, so you don't really loose compression from the cylinder. And while that reed valve looked rusty, they still function just fine after a cleaning. Don't pay $650 USD for a new rebuilt pump, it's super easy to change the valve and dry out the desiccant . If you really need a full rebuild, do it yourself. All of the parts are available and there is not a lot to it. I have rebuilt over a dozen pumps for family and forum friends and takes 20 minutes max, mostly waiting around for the desiccant balls to dry out in the microwave. I do understand why Dan replaced the pump though.

Another good one Dan! This actually happened in our shop on a Range Rover a couple of years ago, and it took my (self-proclaimed Genius) boss 3 days to fix it. By chance of course, and only after replacing almost all the components in the air suspension system . When nothing else worked, he said "We might as well put a new compressor in (another $1500) so we'll have a complete new system. We'll tell the customer that everything was destroyed in the accident." I'm sure most of the parts were ok, but we didn't get involved. He always said " I WILL DIAGNOSE AND TELL YOU GUYS WHAT TO DO". Later on he bench tested the old compressor and sure enough it didn't produce any pressure.

Swap the hydraulic lines on the swing motor at 3,000 psi Whatever was stuck broke free. Reinstalled the lines back swing action works fine. Customer was amazed & able to finish his job, it's fun to fine the cause of the problem. I did replace the hydraulic filters once the machine completed it's job. I had fun explaining to the reps that built the machine. Luckily my boss videoed the whole thing to cover it under warranty.

[@sinegra30]

Excelent fix Danny thank you for sharing! It was a nice detail to set the language in your scanner to english for this video. I'm about to get a whole box of those blue rubber special multi purpose tools you have! This video reminds me a similar problem I had with a Porsche cayenne Turbo, It was my first air suspension ever, I remember the front of the vehicle was really low so checking air suspension for leaks with some soap and water mix I found that the front left suspension was leaking air so I went ahead and replaced both front air suspension air bags (They sell it apart as one piece on ebay instead of the whole assembly) and also replaced the right side height sensor because the arm pivot was broken, after that for my surprise I could not raised the car with a bi-directional scannner command and also could not even heard the commpressor activating so I checked signals, activation relay and pressure and determined that the compressor need it to be replaced, I did and that fixed the problem, I remember the customer was very happy about the fix but asked me a very simple question I could not answer at that time... he asked me why the compressor failed at the same time the front left suspension failed? After further research I found out that when a air suspension is leaking (In this Porche) the ECU monitors the car height through the "height level sensor" and sends more air to that particular suspension to keep the car height leveled but by doing that the ECU keeps the compressor running more than usual, sometimes depending of the leak it can keep it running all the time and that actually overheat the compressor and eventually damage the unit. So I learned that we need to check first the compressor unit and then also never forget to check for suspension, reservoir tank and air lines leaks in this systems.

From my experience, the compressors usually fail because of leaking air springs that are not replaced until the compressor fails. When that happens, people realize the springs have failed but replacing them doesn’t fix the problem. I have had people replace compressors with leaking springs, only to have the compressor fail again from overuse.

Just because most mechanics use the parts cannon until car is fixed, or until they get fed up and seek help. I suppose they have a lot of air springs fails, and usually, replacing them is the fix.

The noise of the pump gives it away. Most pumps fail because the airbags leak so the pump is always running causing it to fault out. Don't forget the airbags. I've had more airbags cause the issues depending if the vehicle is parked level or in a driveway up hill. Vent valves go bad due to water ingress causing corrosion. Good informational video. As per BMW, the parts come as 1 whole kit.

I had a 69 Cadillac Eldorado with rear air suspension. It used a vacuum powered air compressor that sat vertically in the engine compartment.

I finally installed an aftermarket electric compressor and had no more problems.

It's not super common in The Netherlands to launch a boat. People that own boats, mostly have it in dry docked, close to their house or in a harbour. People generally use a towbar to hook up a trailer of some sort for vacation or hauling purposes. I own the exact same model of this car, and i've seen 2 moisture issues before: 1 where moisture enters the roof lining via the trunk lid. The other one is similar, when opening the trunk lid and the drain holes are clogged, the water runs all the way down towards the fuse compartment. I replaced a relay that was soaked and made sure to tie-wrap it higher. I've also replaced the Air suspension springs because mine were leaking, so it would be the first thing to do on this model, since it's a common fault.

[@igo470]

[@happilyatheist]

Super cool Dan. I had precisely this problem. I knew didn't have leaks after doing bubble test so it had to be from the pump. I found the pressure o/p problem from the pump by using the finger method but at that point I was stuck thinking a whole new pump was the only option. One last search of the web and I found you. Withing 5 mins of watching the video I had the 12v on the solenoid and I had established that it was sticking thanks to you. I freed it up and refitted and now all good. I have a new part on order but need to wait a week for delivery. Thanks Dan. Great video. Great trouble shooting. Great explanation and Great that you saved me £800 at the repair shop. Regarding the other garage up mention - What REALLY pisses me off is that the car had both bags replaced at the other shop for no reason!!!! That's just lazy or idiotic problem solving and then they pass the cost of their stupidity to the customer. I am no mechanic but I can problem solve and if both bags are flat it has to be a part that is common to both bags that is at fault. That means leaky manifold supply line, pump housing, pump piston/ring seal etc.. Anyway, I am having a rant sorry. Dan your stuff is great keep up the great work.

BMW and Wabco ought to be ashamed. Same problems as before. Even the E61 had the same problems 15 years ago. Pump is placed inside a shield where mud/gravel/moist can come in but not out. And Wabco pump quality is poor. Should have a fail safe switch to turn off when air spring leaks too much.

[@Diagnosedan]

You are right😢

[@Uninfluenceable]

it actually does shut off once a leak is detected, (pump not reaching required pressure within given time, 15s I think), and it will NOT allow you to turn it back on during that drive cycle even if you push the raise button, it instead give you malfunction message. However this pump shut-down feature resets every drive/ignition key cycle, so owners tend to ignore it and just keep driving with a leaky air spring. It's a user issue, not a pump issue. I would much rather have the pump come back after a key cycle and at least get me home than have to take it to the dealer immediately.

[@hejasverigeee]

@@Uninfluenceable I agree, Ian. To some extent.

Got my comp off at the minute as both sides are in the deck. (Both air bags new 1 year ago). Finger over the air outlet and could easily stop the pressure. But when I tried dump solenoid it appears to operate, so I pushed a pipe onto the little end of the solenoid and blew. Didn’t stop the air flow whether it was energised or not. So I’m still thinking this is the issue ?????

[@matthewjenkins1161]

Got same type Wabco pump on my Jag, so guessed where this is going. For a fraction of the price of a new compressor, there are kits to replace the piston ring and drier material. Think BagpipingAndy was the first to make this cheap fix available.

[@fjord5207]

Nice to know Wabco decided to save few cents. Stainless steel is overrated nowadays. I have 2x E61 with about 300,000 km and both pump up perfectly without issues 15 years later. It also gets really humid here in the summer.

This video was brilliant. I had my compressor changed just over a year ago on my 2009 model. It lasted just over a year and now I've got another issue with it where the compressor will keep going and not turn off constantly. The right side of the car has dropped, the left side seems okay

[@rrmech11]

It's blows like a air tank now. Nice job DD

Thanks!😉

Nice video Dan but very expensive for a new compressor . I suppose that's inflation for you... Your still the man.

Great topic Dan. I’ve never really touched air suspension but your video has given me enough insight to at least have a go and get started.

[@Diagnosedan]

Thanks Russel!

I just came across this video. I went ahead with spring conversion on my e61 (to be fitted soon) as the EHC module have failed. I have found that these systems are way too complicated for what they are. I have seen a lot of happy guys after doing this, so for me, this was the simple answer and I can always go back to the air suspension. Full conversion kits are available on eBay for a range of BMWs cost is around £200 + coding (you can code it yourself if You know what are You doing...) which is about £50 - 70. I will see how easy it is to fit within next couple of days. If You are interested send me a message for updates. FYI i do not sell or do any coding so this is only my humble opinion. Edit: forgot to mention peace of mind after this... No problems with compressor, air bags, hoses, filter, electronics.

My f11 suspension failed today. I jumped the relay in order to get the compressor running, both air springs are empty and did not fill. I suspected a worn compressor piston seal, but the solenoid valve seem more likely. Thanks for the tip, I'll look in to it tomorrow!

[@Diagnosedan]

Good luck!

[@martyg3757]

@@Diagnosedan Can you place a glove over the outlet and cycle the pump to verify the leak?

[@jamesdennis7067]

Dan I replaced my relay and air compressor on my how 510d f11 but suspension still drops ( no leaks on air bags) any ideas

[@nickidewet7711]

Just how could the previous shop not diagnose this simple one? Shocking.

[@Diagnosedan]

They told me because of time pressure🤔

[@gonzgarr1592]

it's amazing the previous shop did not check the compressor for how much air it put out first

Nice Job..This is Same problem with Ford Lincoln Town car.. I used a regular air pressure gauge...

[@Diagnosedan]

A lot of people are talking about that Lincoln!

[@GNX157]

Dan, this is the Mark VIII commercial. They did it driving under an airplane wing too. The Mark was constantly raising and lowering. At highway speed it would drop, then when you slow down it would raise, then also from raised pos when you'd park and exit the car it would drop again, don't ask me why, it should of stayed raised, because as soon as you were in and driving it would raise back up, all normal operation, very busy system.. All this plus the Goodyear airbag was a crappy design prone to cracking due to sever fold over (under). Front had two sensors, back it treated two bags air with one sensor. Also, door jamb switches acting up would throw the system loopy when it thought you were going in and out of the car but really weren't. The biggest weakness was the desiccant canister. Hard to reach and ppl didn't know to replace it to keep the system dry, which would of stopped a lot of moisture related problems. kzbin.info/www/bejne/nXzbeoVqls-ajMk

[@bmw_m4_alpinewhite]

Dan, love the diagnostics! But, that is a pre-LCI BMW F11 5-series build from 2011 - 2013. Air suspension goes bad all the times on that specific model and build years. In the later LCI versions, very little air suspension problems.

[@alexandruchivu7327]

Great materials, Dan! As usually with BMW, you pay more because of the brand. Greetins from Romania!!!

[@ToddGlasier]

Holy Cow a mind blowingly terrific video walking through this diagnosis. My 2012 e70 X5 may or may not have the exact same compressor. It raises the vehicle fine, but overnight BOTH sides drop, so got a leak somewhere. Unlikely that both airbags failed together. Each has a dedicated air line running back to the compressor, so also unlikely both lines failed together also... So now I am looking into if there is a component on the compressor, upstream of the 2 air lines that could be leaking. Possibly the 'vent valve'? You mentioned a 'valve block' too but not sure what that is. Thanks if anyone can provide a pointer.

[@robertoruiz7069]

Hi Dan,like your videos. MY guess at 7 min in was a bad pump part and a customer that was OVERCHARGED for 2 shocks at how much? 350 ea? WHY?because the other FAILED to properly diagnose the problem.At the very least they should refund,all of the parts cost but keep 100.00 for labor.I would have deadheaded the pump or put a gauge inline to one of the shocks to see what the actual pressure was on the line.i may have even used my bicycle hand pump to put pressure in the lines lol.but that real old school..thanks Dan

Per Ivan parts cannon was loaded. Why wouldn't anyone check pressure first. Anyway another great video Dan. Thanks

[@Rabee1977]

Hi my friend, how are you doing? This compressor always breaks down from a lot of work, you are always creative, but it appeared to us this time, I hope to see you always with my love and my respect for you

[@alistairpowers8129]

Nice one Dan, It was good to find out what caused the failure. And even better to know after market parts are available to rebuild it if required. All too often the end user is unable to get the parts to rebuild (See Range Rover) With it being just two years old would the warrenty cover it? I guess BMW should really re design the pump system to ensure dry air in all climatic conditions

[@TonyRule]

I too would have thought it would still be under manufacturer's warranty.

[@Diagnosedan]

The car was imported from another country and than in some cases the Local reseller doesn't provide waranty.

[@nicknicu1787]

Have you noticed Dan’s cars are always spotless? I think he cleans them,full detail,clay bar and wax before filming. 😁 Another great video Dan! I like your pressure sensor set up. 👍

[@Diagnosedan]

I knew someone was going to mention this🤣🤣

[@mike-yp1uk]

I was hoping to see the motor commutators signature and see the amp and rpm before and after. I think it's possible to test it at the fuse block. Like a fuel pump? It's awesome how far you take these to the end.

[@bbkmm1]

I was hoping the Technicians in Holland are a lot more informed. Since the tests are more stringent and there are more regulations. It's the same as here in the U.S. where any Hillbilly can open a shop and swap parts.
