Here's Why Your BMW Runs Like S***, And How You Can Fix it For Only $3

We have all been down this road before. Your BMW is running less than optimal and you don't know what's wrong with it. Misfires, limp mode, drivetrain malfuntion can all be a pain in the rear. Most people will ask you if you've checked the spark plugs, coil packs and even the injectors, you know the usual. But what if I told you it's not one of those things and instead it's something you can fix for very cheap at home? A fix that is commonly overlooked that can save you hundreds of dollars. That's what I'll show you in this video.

[@stevensims3342]

Yes and on a E90 328i these are so easy to get to. I was reading you can clean and swap them. Some have speculated they fail by getting stuck from performing the same operation while cleaning and swapping them allows a slightly different movement effectively freeing them up. For installation you actually want to carefully lay the new or old o-ring into the spot where it tends to stay when removing the solenoid. There is a little shoulder for the o-ring to sit on (stage the o-ring) after staging it in this manner the new or cleaned solenoid will easily slide in flush. Being that I've seen people struggle to press the entire o-ring in with the assembly when installing. It is very difficult to compress the entire o-ring like that.

[@faizi_notfound]

I cleaned my vanos solenoids following your steps and even swapped out the cover with one from Europower Motorsports. My BMW runs like a dream now, no more misfires or limp mode. Thanks for the awesome DIY guide!

I can confirm this works, a shop wanted $600 to do this job and they said they were only going to replace one and clean the other, so if they replaced both with brand new ones it could’ve been more like $750. I said to the guy who works there “that’s a little expensive isn’t it? Especially since you don’t really need to take anything apart to get to the solenoids and they’re only held in by a couple bolts.” He gave me a bunch of excuses like “well it’s an expensive car, blah, blah, blah...” I told him that’s okay I’ll fix it myself since he wouldn’t budge on price. Since I declined their service they charged me $250 for an oil change and diagnosis! I bought one solenoid and cleaned the other one out for under $200 and have had no more issues after about 8 months. Will never go back to Bridgewater motorworks in Bridgewater, Ma. Bunch of scumbags who think they can charge dealership prices for simple jobs.

[@fredfrederickson]

I would recommend connecting the solenoid to a 9v battery for 2 reasons: 1. You can test if you need to buy a new one if nothing happens when power is connected. 2. You won’t be able to clean out the inside of the solenoid completely without connecting it to power because the parts inside move. You should keep disconnecting and reconnecting to power so that way you can move the inside of the solenoid around and do a much better job of cleaning out its internals. As you clean it out, you should see the solenoid begin to move easier and easier until you are satisfied with its performance and can stop cleaning. Edit: I would also recommend buying new gaskets for the solenoids, they’re not too expensive and you don’t want oil leaking near your belt.

Although those 2 connectors appear to be the same, they are in fact different colored coded wires, DO NOT plug them back in reverse order. They both have same connector type but have different color wires, if you connect them in the wrong slot your engine will run like crap. Take note of placement upon disconnecting. Great vid as usual. Thumbs up.

It would have been nice of you to mention the non return valves on the side of the head.

Before you change these, check the female input on the connector. The pins (male) on the solenoid is very thin. The female connections can spread with time making faulty connection.

Not too familiar with BMWs, but I know that in general, cleaning solenoids or sensors only helps for a little while. They will go bad eventually, so you'd definitely want to be in the mindset that you will be replacing the solenoids eventually. This was a great and informative video though! Looking to pick up a 2011-2013 335i M-Sport in the near future. They're just super hard to find in the spec I want :/ Edit: when reinstalling o-rings, you want to use an o-ring lube, so that it slides in smoothly and doesn't crack or get pin holes when you put it back in.

[@SkwillexHD]

Thumbs this up to help follow BMW owners out Tips: -If you're trying to diagnose just 1 solenoid (ex intake vanos codes are present) remove them, clean them, and swap their positions. They are the same part number and can go into either intake or exhaust side. If you swap them, and no codes return, problem solved the cleaning work. If you swap them, and the code then moves to the exhaust side, you know that solenoid is probably needing replaced -If both solenoids are replaced and you are still getting the codes, it could be an indication your cam ledge bearings need replaced. This is most commonly due to poor oil service maintenance -Sometimes the solenoids ARE A PAIN IN THE ASS to remove. Many YT videos I've seen them just simply pull out. Me personally I've had to take a flat head and try to pry them out -Don't cheap out on these parts. Just buy the BMW OEM one. I've tried the Gates ones before and they survived for a bit, but after a while the codes came back. Spared no expense replaced with an OEM BMW part and no problems. I dont know, these engines are so electrical sensor sensitive sometimes you just got to run the OEM part -The O Ring can make them a pain in the ass to install. Make sure to put a bit of oil around the O ring. I personally had to take a little rubber mallet and tap the solenoid back in to get the O ring to seat properly

[@mathewanderson9330]

[@ecisnerosvivas]

More tips: good idea to lube the seals with o’ring silicon grease or engine oil before putting them back on, good advise replacing the solenoids at 100K miles, be extremely careful not to swap the electrical connectors, the engine will get crazy, my advise is to remove, clean and reinstall them one at the time. With the engine off the base settings of the camshafts is as follow: intake camshaft retarded and exhaust camshaft advanced, this is also the safe position in case of electronic control failure. When the engine is started, the camshafts remain in this position until the ECM detects the position of the camshafts from the sensors (50 rpm’s or 2-5 seconds) the ECM makes an initial timing based on oil temp, oil pressure and rpm, the solenoids are a very important part of the engine controls.

You should pull the anti return valve bolts out of the side as well. Mine were terrible and that was what was throwing the vanos code.

[@fishonnelson2353]

[@NeoNacho]

There is also a bolt on the left side of the motor that has a filter grate on it that also can get closer clogged up and dirty. It also relates to the vanos system.

[@jrock865]

Another side note when doing this also clean the one way valves they're located near the tensioner bolt They're t40 i believe and pull them out ...taking the passenger tire and the inner fender plastic out will give you better access but take them out and clean them off to where you can see through the screen filter. Also check your oil filter to make sure it's not broken or damaged these things along with vanos throw vanos codes.

Running perfect, overtook a lorry then it started to run bad, so your telling me a mechanical system" wore" out in 200 yards? " once he had stopped squirming and going red he asked me to leave it with him. Two days later he said he had adjusted the valvetronic motor clearance 0.4mm and it" was a lot better". It was acceptable but not perfect, put with this the struggle I had changing the aircon hedgehog and the alternator and auxiliary belt tensioner and idler I sold it to some chav family who subsequently wrapped it round a lamp post some 6 months later and writ it off. I was put off by BMW but about 4 years later bought a two owner 2006 44k 320d, absolutely mint, se model, I then read about the swirl flap problem even though mine were the much improved plastic versions not like the e46 and how they can blow the engine up "if they fall into the engine". due to the corona virus lock down, the decision I don't like driving around in a time bomb and I only did 200 miles in it in ten months I flogged that as well. I read about the petrol engines on my year and problems with cylinder walls crumbling, one with the timing chain facing towards the rear of the car which believe it or not has chain problems so it's gearbox out to fix it and I've made a vow never to buy these pieces of overpriced bits of junk EVER again, add to this the clowns who claim to be specialists who can't fix them. I've still got my e30 I've had for 25 years (last ten years just sat in the garage) it never gave me any trouble. BMW? = big money waster

I had two misfires after doing a DIY carbon clean up. I ran Red Line fuel system cleaner and after a few more fuel up I ran a 20oz of Techron. My '13 X5 35i had had brand new plugs and coils so I blamed it on the injectors (I got over 100k miles), the misfires didn't reoccur even after driving the X5 pretty hard! Gonna have my mechanic to clean the VANOS solenoids on my next service (coolant flush+new serpentine belt).

This will b helpful down the road. Thanks👍🏽

[@chrisneil862]

Another way to make room is to take the fan out. Like 4 bolts and an electrical clip. Gives you way more room to work.

[@michaelvoorhis9555]

For me taking the fan out was a LOT EASIER than getting it back in ... plan for a bit more time getting the fan back in correctly.

[@atlantajunglepythons1744]

100% agree that his job would have been lots easier by pulling the fan! Learning how quick and easy it is will take a lot of the burden off doing any of the jobs needed on the front as the n54 ages; for instance replacing the mickemouse fitting and any hoses that cross the front; the serpentine belt and idler pulleys; radiator; intercooler; etc.

[@dsolo3250]

There are two oil screens that supply the solenoids on the turbo side below the valve cover you can clean them too. They are part of the screws that you remove in the head.

[@kitana3977]

Before replacing the solenoids always worth checking the two filters located to the left of the solenoids (under the exhaust pipe of cylinder one. These are only accessabile from the right wherl hub by taking the wheel off and the coverplate. Need a torque driver and patience as pretty hard to get too. Mine were nearly all blocked so will check them again before next oil change. Good luck

[@thebavariancircle5105]

Cleaning is a band-aid. I can’t tell you how many time I have cleaned them for the issue to come back. This will help you save a little to get them and replace them.

[@jblvxk]

I cleaned mine today car was running perfectly fine then half check engine light came, car still runs perfectly fine and idles fine no misfires. Should I go ahead and replace them? Would a full oil change help as well, cars 06 3 series 130k kms

[@m00seknucklejohnson45]

Is there any risk of the brake cleaner damaging the part?...would mass air flow sensor cleaner be a better option since there is plastic?

[@atlantajunglepythons1744]

I think MAF cleaner probably would be better. I bet most DIY-mechanics have a mostly full can laying aboot

[@Likadees]

Well explain and the details of how DIY! New Subscriber! Cheers.

[@colinpadley1897]

Your site is a great help to many, I'm sure, I think for all your time and trouble, you should set up a patron connection. Are seem to know these cars inside out? Are you BMW trained?

[@AZTECPRIDELOCOS]

My son owns a Bmw 3 series and damn this cars look so nice but when it comes to do some jobs you cant even put your hand in it 🤟🏽🤟🏽 thanks man doing that for my sons car

[@sammyjames1929]

Imagine how easy that would be with the engine out 🤣🤫 coming along though will be nice to see the numbers once your tuned👍🏻

[@VehicleVirals]

Honestly at the time I didn't think about the Vanos Solenoids lol!

[@rosewd2]

I saw a 2aaf error on your scasnner, you may want to replace the low pressure fuel sensor. If the pump is actually getting weak it could damage your high pressure fuel pump. And usually that tasked a few injectors with it when it fails. BMW does cover the hpfp under the extended emissions warrenty - you have to point that out of course, but not the injectors.

[@kenbina]

Great video and thanks for sharing!

[@ColeBender]

Fun fact: today when I popped the hood on my N55 my coolant reservoir cap was sitting 3 feet away from the reservoir and on the alternator. No idea how it got there.

[@VehicleVirals]

[@rskrks]

Hate those vanus selenoids Also i hate the essentric shaft sensor, the oil filter housing gasket, all the water hoses, those bosch coils, the weak control arms and bushings that cannot handle nyc. Other then that i miss my e90.

My car ran fine(with proper maintenance) for 2 years. I slapped a tune on it and all those things started popping up.

[@kurtgoar519]

Excellent job on this video... Thank you sir.

[@robertoquintanilla4757]

I have a 2003 525i is running good but this video it's very helpful Tha thank you i do appreciate thanks again

[@javianjohnson8746]

You just listed 2 of the codes that my car is throwing at me. I’m DEFINITELY going to try this out first. Wish me luck... 🙏🏾

[@emmanuelperez7946]

Any update on the results? Did it work out?

[@emmanuelperez7946]

Also which 2 codes popped up for you?

[@homerthompson6028]

@@emmanuelperez7946 didn’t work that’s why he’s quiet

Funny how my check engine light went away once I cleaned these out lol

[@unL33T]

Sounds like what is expected...
