335i Engine Management light - Vanos, solenoid valve, bearing ledge etc.
I've had the engine management light (reduced power) light come on twice now and it says it relates to a blocked pipe or something, can't remember the name
The previous owner took it in and they flushed it & adjusted the timing, and now I've just done that, I suspect he took it in more times than paperwork suggests and that's the reason for selling? I found a good topic on N54tech that said next they replaced a bearing ledge, and then solenoid valves but the light and reduced power was still coming up after many trips they eventually replaced the whole Vanos unit & he's never seen the light since was wondering your experiences and if it did stop after a few repairs or just asking BMW to replace the whole unit is best and will save everyone's time? I just renewed extended warranty with £0 excess so makes no difference to me! |

You need to read the codes.
It could be any number of things. Dont worry.

BMW read the code and said it relates to the blocked vanos unit, so they flushed it & sent me on my way
I only fear this will keep happening without any resolution

Drive the car hard everywhere until the VANOS faults flag up again
Go back to dealer and say the car needs sorting as it has been botch fixed unsucessfully by them a number of times.

about 52k, and yeah it normally triggers when accelerating hard in 3rd gear, like over taking or something, maybe 20 mins into a drive ?

another one bites the dust....
In your list....maybe replacing the coil packs might be worth it?... But you have to read the codes and find out where the problem lies... |

2) If you dont have a code reader go to a dealer/Independent, you could spend thousands replacing things which dont need to be replaced! much cheaper to just get the codes read and replace the correct thing..

my car is AT. When i press full gas, after change gear, halk engine light come on! i said them " dont replace anything without inform me, especially chack the vanos solenoids " and i learnd another thing from philip; Mine was a small plastic nipple on a hose that connects to my wastegate, it was cracked and so the monitored boost didn't match up to the expected boost and it shut off the turbos to prevent any problems. The replacement metal part was less than 2 dollars and took about an hour to diagnose and replace. I don't think the HPFP problem is as prevalent nowadays, simply small vacuum leaks. __________________ -Phillip Wilmeth BMP Design - BMW Parts Headquarters since 1983 www.bmpdesign.com - 1-800-648-7278 Also be sure to check us out on facebook! |

http://www.realoem.com/bmw/showparts...67&hg=11&fg=15 One for the intake and one for the exhaust. Same part number. They are fairly easy to replace if you have a few tools and are not afraid of a bit of DIY. It probably took me 45min doing it carefully. My exhaust one started to stick at Brands Hatch, so I just replaced both. INPA was able to read the sub code that the cause was stiff/jammed VANOS, but without reading the codes you are really guessing. If it is the VANOS solenoids, then you can probably clean them and get some more life out of them but eventually they will fail. For the sake of faffing around for £160 I just replaced both of them and it's be good ever since. |

Thanks to all friends...
i solved the problem. Thanks Allah... Service thinked to change vanos solenoid But i didnt because when now it doesnt have any problem. İn my opinion the problem is little petrol. Fuel. When i got the car from dealer. İt has very small fuel Reason of "half engine power" is that When i got completely full fuel After 200-300 km everything is ok. Again thanks for all interest friends ) Best regards... |
