You have had this car for a week and you are already making tutorial videos! 50sKid I hope you know how truly appreciated you are in the BMW community. First e46 - now e90. Thank you so much for all that you do.

don't own an N54, but I´ll still watch! hahah.. great channel

The white bandana...essential gear for BMW repair sessions :-)

hey 50skid I wanted to thank you for all your videos I recently rebuilt my e46s engine and without your amazing videos I wouldn't know what to do keep up the amazing work and I hope one day you reach 1 mil.

I love when there's a car problem and it's not so hard to repair, especially if there’s a DIY video from you. I’m really excited about more videos coming. Thanks 50sKid! 🔧💯

Great video!!!! I dont own an e90, but still watch these videos cause i love watching people wrench on bmw's!

I’m glad to see you with the 335, I’ve learned a ton from watching your E46 videos. Thank you! I’ve had a number of E46’s. They make great first cars for my kids. Now my wife drives a 535 and I had a second one for a few months. I noticed your video wanted to share this trick I found. The boost solenoid should hold vacuum when it is working properly. I used a harbor freight brake bleeding tool to draw a vacuum on the input side. The worn out solenoid may not hold vacuum very well. The new one will vacuum. Recently I had two 535XI’s and the rear solenoids would not hold any vacuum, the fronts would drop pretty quickly, but I could at least somewhat draw some vacuum. If you still have your old solenoids, give it a try. Both my 535’s would exhibit the 30FF low boost code. After replacing both solenoids I no longer got the 30FF even under full throttle pulls.

Great to see you back 👍

Hi my friend , good work thaks for this video very important Good luck Greeting from Italy 🇮🇹🇺🇸 I love U.S.A

glad your back, saved me hours and money, also want to upgrade to a 335, my 323ci is starting to feel slow after driving it for 3 years, Respect from Sweden.

Awesome show !! I did these on my Wife's 2010 535i. I wasn't getting a code or loss of power . I was getting a humming noise. I replaced both of them.

With an N52 engine in mine I'm not sure what I'm doing here... I guess it's just that lore of the 50s kid. Great content and so glad you're back!

This is the best and excellent video about Boost solenoid Valve. I have the same boost problem on my BMW, I have bought the parts and i am going to replace m boost solenoids today. Thank you very much for your sharing. Keep on he good work.:-))

Thanks for the theory of operation and your troubleshooting step. NOT MANY OTHER VIDEOS DO THAT. THIS IS WHY YOU ARE THE BEST. One thing I learned is that when the CEL is red, stop engine, why?

Thank you, finally solved my overboosting issue (30FE + 3100).

50sKid, your videos are easy to follow because you explain everything in detail. Good job! I’ll test my boost solenoids the same way you did. Thanks!

I love your passion and attention to detail and the fact that a non OEM bmw fastener bothered you. Keep doing what you're doing sir. Looking forward to future videos with your new project car!! 😁👍

Hi, thank you very much for an excellent video. I have to do the same job on my BMW 525D Xdrive N47 engine. Now and then I loose power. I have already replaced 1 Boost solenoid and 1 Charger pressure. My next job is to replace the last boost and Charger. Very much appreciated video. It helps me a lot.

So happy to see you back! Learnt a lot from your E46 series and it helped me with my E46 project. Have a E90 N54 - love you started a new series!

Great video. Thanks for giving some love to this car. I own e91 and love it

Love the paper trick. That will save my ass in the future. Thanks 50’s kid!! Btw. I found your channel when you had the e46 and you were solving my problems, then I got an n54 and you get one too!!

lmao i have the same problem on freeway pull after i repaired my wastegate rattle, and at first it really was my wastegate adjusted improperly, so i dropped the frame and readjusted, the code did not came up until i took it to race track, and canyon run, so i dropped the subframe again just to adjust it, now code never came up but boost is no longer matching the boost target. im starting to think that my BOV is not being responsive enough. lol, anyway thank you! now im on my way to change my boost solenoid.=D

Bravo, Jason! 👏🏻 I agree...that non BMW fastener would bother me. In fact, I noticed it right away before you even mentioned it 😝 Who knew you were a golfer?? 😎 I must get me that Milwaukee. I recently bought their underhood M12 light and it's great. Also nice when doing interior work. I'll check out your parts sponsor there.

Thanks for your diligence in all the work you share

I had a boost problem on my N54, I have an aluminium charge pipe with a bov and a Cobb access port tune , the boost would only go up to 16 psi and then drop like a stone with the engine light on and a 30ff fault code on my protool app , great I thought this could cost me anywhere between £2 and £2.000 + , as it was it cost nothing and was an easy fix but not such an easy reason to track , the T map sensor had popped out slightly due to the retaining bolts partially stripping due to being to short , fitted longer one's that I had lying about and now I've seen 19 psi with no problems .

I have the exact same codes and issues with my 335. After searching for some info on this I stumbled upon your video. Thanks for the informative and detailed DYI video. Going to harbor freight now to double check but I’ll order these boost solenoids being that my car has 150k miles. Im sure that is my problem.

Thanks for all your videos I have a 2001 325i I have save so much money looking at your videos thanks you brother

Thank you for the information and video. I think that's what's going on with my BMW. I'll have to test the boost solenoid valves like you did first.

Can the bad boost solenoids also throw a 30ff code? Instead of turbocharger pressure too high 30ff is too low. I'm having similar issues but no half light just misfires on cylinder 5 and 6

Excellent man u make patience essential to working g on these machines

Looking forward to all the things you do to the 335i. In the process of a motor swap

I would’ve liked to have seen some video of the 335i afterwards running sweet and smooth.

Aye guru. I got a 2002 x5 that won’t let me scan the obd port. Checked fuses. Fuasable links. Changed batteries with 2 other charged ones... even had my jumper on there too with extra juice.. I just get low voltage can scan car... I checked the dme and tcs. Car is in motor and trans fail safe prog.

Will this indeed cause a constant buzzing noise from my motor? It even does it for a second after I shut the engine off. I have a 2008 bmw 535i. I’ve never had engine light come on though

Cool vid. They were both leaking by the look of it, #1 wasn't exactly hitting zero either. Evidence that these things are eventually going to leak.

great video! 👍

Life saver thank for the troubleshooting. No wonder 💭 I can’t boost

MHD show a low boost code 30FF. I did a smoke test for vacuum leak couldn't find any. going try replacing Turbocharger Boost Solenoid Valve. Remove top cover plenty room to work on solenoids. no need to remove the canister

If anyone is wondering how these work. Stock boost converter solenoid is normally open. Vacuum is pulling through it and holding the wastegate closed, ECU sends ground to solenoid when desired boost pressure reached, solenoid closes, removing vacuum from wastegate and the wastegate spring opens, bypassing exhaust flow through wastegate. They fail by either leak or valve getting stuck open/closed from what I've encountered.

Please help. My Snap-on scanner threw 3100 and it said Boost pressure control, switch off. Is this similar to yours stating deactivation? I'm thinking so because different brand scanners word things differently maybe?

that milwaukee though 👀👀

Hey got 04 e46 and I only get sound out of the driver side speakers what is the issue is it the amp

Back with a vengeance... Thnx 50....

And another great DIY. thanks...keep posting

Great video, waiting for my solenoids to arrive, went on a first trackday and sure enough didn't have the right power on the straights and got 30FE, 30FF and 3100 with a half check engine light. Driving home at night, the car pulled better in 6th than it did in 3rd and 4th at the track, strange... hoping it's the solenoids and maybe the hoses, will replace them because it can't hurt to replace 13yo parts :)

Ive always assumed that my wastegates are worn due to a tinny rattle that sounds like an exhaust heatshield rattle.After about a minute the rattle disappears as the revs drop to normal after initial warm up.If i do this before driving, the car is fine.If i drive off before waiting , then within a few yards that yellow half engine power light comes on. I then have to stop, turn off, start engine again and all is fine. Ive always imagined that the vacuum pots lose their vacuum when parked up for over 5 hours.Maybe its these solenoids ?

Great Video, as always! Thanks for sharing!

wat about the transmission code wen u gonna fix that nd btw the bolts that hold the expansion tank r 10mm bolts same on my n55 they r not torx fasteners but still oe hardware

Great video man,I been watching your videos for so long.I love bmw and I always have one but I never have a good bmw scanner help me find a adorable bmw scanner i need one thanks.!

Hey bud. Have you done a video on replacing the air intake manifold? Mine craked open

Is it ok if the boost solenoid is wiggling? The round part that has the cut out for the driver to fit on to the nut.

Do you have a video changing the turbos and also a video on roof rattling on a 335i e93 hardtop convertible?

👌

Great video really helped thank you

Hey 50sKid, great to see you back! I have a 30FF code(charge pressure low), would changing solenoids also fix the problem?

I think I’ll stay with my e46 ahaha a lot more simpler to handle

I cringe every time I see an "aftermarket" bolt. Not so much because it's not a BMW bolt, just that it's different from the other(s).

Will this test work if you have a bov blowing air out to the atmosphere?

What's the idea with people referring to these engines as having 2 banks ?

Hi there. I know this doesn’t pertain to this video but I’m posting it here in the hopes that it’s actually seen. Thanks for all the terrific videos. I’m in the market for an m56 valve cover. Do you still sell these? I’d like to buy from you if possible as a kind of thanks for all the great information. Car is a 04 330i looking for a ccv fix for cold weather.

Is that whine normal ????!!! I’m having that

So a boost solenoid can cause a overboost issue? I thought they were mainly responsible for boost too low situations?

Legend

What’s the part number?

I have no codes

Which scanner do you use

Did you rid of your e46 330?

So the car isn’t so bad, and for the money you probably paid for it it’s a freaking performance bargain

Remember! They don't always throw codes, the performance can still be terrible and still have no codes!

N55 do not n have these issues

Get a Bmw e39 540 and make some videos !

make it into a drift car
