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.

YOU JUST MADE MY DAY. literally been misfiring for a year and a half, upgraded to index 12 injectors, coils and spark plugs three times, and i was still misfiring. watched this video last night and did it today and she runs beautifully! appreciate it man!

[nikos.k]

DUDE! Just after watching your video randomly, my father called me and told me that his e93 went on limp mode. He went to the dealership and guess what?! Faulty vanos solenoids! Thanks man!😁

[fredfrederickson]

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.

I love people like you. Helping others without asking for anything. Thanks!

It’s funny that I started having these problems today and lucky enough this video came out at the perfect time

[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.

I've had misfiring for the last 5 years, and no one has been able to diagnose it. Had turbos and injectors replaced under warranty. 2 sets of coils and plugs.
Found this video, pulled the vanos, and cleaned, and after warming up the car, made 3 hard pulls. No misfires! No codes!
I have JB4 BTW. Thank you so much for making this video!
Should the issue return, I will replace vanos myself, because now I'm a pro!

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.

The level of detail he leaves for us is like no other youtuber

I have a 2009 Mini. Replaced these twice myself. Thank God for guys like you that put this info out there for us home mechanics. I was going to replace the timing chain on my Mini. I was lucky I saw a video a few years ago that said to check these Vanos first.

[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!

My car it's 335is, feel a strong sound and slow acceleration, and the engine may feel tired. I watched your video 🎥 right a few days ago and was thinking to do it. The results are impressive 👏 I can't believe what I'm see the different it's amazing 😍 I swear to God, man thank you so much 🙏

[stevensims]

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.

Dude. I just did this and it fixed my misfires on 2 and 3, INSANE. THANK YOU!

[skyy]

Thanks so much dude, was totally getting misfires, changed everything and still was throwing them. Tried this trick and drove the hardest I ever have and it was smoother than ever.

[jacks.]

I was quoted $3000 with labor to replace my entire vanos system at southwest bimmers of las vegas. I refused service and did some research. Come to find out some brake cleaner was all i needed to pull it out of limp mode. You made my entire week bro, Thank you.

[rodrigovelasquez]

Thanks for the video bro, I bought my 2008 E92 335i because of you, couldn’t be happier! And everything I needed to fix/replace was on your chanel, thanks :)

[Dafonso]

Bought a beautiful e92 335i off copart and fixed her up nicely, but was having shaky start ups, hesitation after throttle and the whole works... was almost ready to just sell the car and grab my profit from it, until i tried this man. you’re an absolute life saver, been watching your videos for a while now and they’re worth every minute! best bimmer guy on youtube bro keep it up

[chavezwalden]

You have no idea how happy you just made uh brotha... My car has been hesitating like crazy under heavy acceleration; so much to the point I actually took it to a local shop to see if they could tell me what was wrong. Coil packs and plugs have been changed recently. (they didn't know to tell me) I think you just solved the issue!!!! Much appreciation to you! Keep the videos coming!
