Symptoms & Diagnosis of a Failing VANOS Solenoid!

[@MingeShagger]

I have an 08 550i with n62 engine, i believe i have the same problem. On my car, it only happens if the car has been parked overnight with temp dropping below 40F, it will misfire until the engine warms up and then no issues after that. I've changed coils and spark plugs and didn't fix the issue. This morning, i disconnected the vanos before starting up and sue enough no misfire and no rough idle. I will clean them first before replacing, great video, Thanks.

[@8020Media]

M - Thanks for the feedback! Hope it helps.

[@friguy4444]

Thank you for your help in explaining the symptoms of this trouble. Well done video! A couple of things to note. The S54 doesn't use those solenoids. As well BMW doesn't Use "P" codes. Generic readers use them and they are fine except when we're using the actual BMW reader we won't know what you're codes mean as we don't get them.

[@8020Media]

F - True. Thanks for the feedback and sharing this insight!

[@sleepydragonzarinthal3533]

but if you are using a BMW specific scanner, wouldn't it define the codes for you anyway?

[@Bandwidth24]

The number one cause of rough idle and vanos codes in BMW is the vanos cage missing from the oil filter because it was thrown away with the old oil filter, the second is low oil and clogged vanos. If you find black fiberous stuff on one of them, your car sucked a serpentine belt at one point and the cams are probably damaged as well or the cam vanos stuck.

[@8020Media]

B - Thanks for sharing this insight!

[@igorcvetkovic2112]

i had a N54 exhaust camshaft sensor / vanos error code. did a liquimoly oil additive cleaner and oil change, also cleansed the two non-return valve metal filters under the right wheel well. seems to have solved the problem. got new vanos from FCPeuro, but have not installed them yet, as i have not had any further issues. i do my oil changes every 10k km.

[@TheNascar991]

I absolutely agree..but bad Vanos will also cause codes for different sensors acting up..ie throttle range..studdering...pressure sensor and so on..also causing you to run in limp mode.

[@MrGhastlyMonkey]

@@8020Media yeap! Used ISTA+ to diagnose , was a intake side cam ledge bearing failure , it wore out just alil which cause vanos not to be able to hold pressure Reason why i kinda knew it was the bearings was because code didnt come up until it changed gears which led me to believe pressure was not sufficient to support the vanos

Good video for the most part. I 100% disagree about not using the BMW solenoid. I own 11 BMW’s right now from E46’s to E70’s. I’ve replaced about a dozen of the vanos solenoids and after the first four Pierburg failed within 6k miles I started only using BMW. Yes you can save about 50% using Pierburg but to state they’re better quality than BMW is a false statement

Is there a difference between the n54 and n55 solenoids? Apparently the n55 is an updated version but i wonder if they're interchangeable..

[@8020Media]

They are different (and more expensive for n55) but I've never tried switching them out. Haven't heard of anyone that has but all of the aftermarket manufacturers too have different part #'s for N54 and N55 so that's a pretty good indication that there is something different enough

[@8020Media]

R - Have you taken it to a shop? What drivability issues are you seeing?

[@Ricys]

@@8020Media basically you start driving even with your foot to the floor and its as if it has 50 horsepower. the revs go up so slow that the ecu takes a second or two to gear down and then i get a high rev jump of speed, that makes daily driving it uncomfortable as i struggle to merge smoothly every single time. also some cold startups struggle and need me to gas it up to keep it starting, sometimes not always. rarely it also has a rough idle, or should i say a jumpy one. i havent felt any misfiring nor do i think it went into limp mode as far as i know but it's too slow and running lean as it is (bad gas mileage). also, manouvering on parking lots going from drive to reverse to drive or whanot has a chance of it stalling. i took it to the dealership for an oil change and coolant to be done, they didnt find the exact leak nor gave me an estimate or told me what to fix kind of useless to get an inspection there. same driving with new oil. if it's not the solenoids and it's some sort of air leak causing this as well as it running lean i am not sure at all where to start looking. else it could be a weakening fuel pump as it is a high milage car with no record of it having been changed

I replaced the battery the throttle body and the maf sensor i just recently put in a new camshaft position sensor. I started the car and it was kinda still fluctuating up and down. Ive been trying to figure this out for a few months now i have a vanos solenoid code but i want to know would the solenoids be the reason of why the throttle codes are being pulled.

[@adasterdezaster2865]

If the 06 is a M54 engine it doesn't have solenoids

[@theoutsider6191]

If oil quality is likely to impact the solenoids getting gunked up, would doing more frequent oil and filter changes help mittigate this problem? BMW have moved to 2 year service intervals for oil and filter now, certainly in the UK and Europe. Although i have never gone over 12 months, and being as i now own a mid 2019 M240i i am considering no more than 6k miles or 12 months whichever is first.

[@8020Media]

@@8020Media Yeah i thought you may say that. When i was looking at cars i saw a JCW mini that had been 3 years since it's last oil service... didn't buy that one, and decided to go M240i in the end....
