  1. E60 M5 (2006 - 2010)
    for reasons, i had to let my '08 m6 sit outside over the past yr ;-; some rodents made a nest and chewed the wires going to the vanos system on bank 2 only damage i've found is (what i'm pretty certain is) the bank 2 vanos / cam position sensor wires, a few inches from the front of the motor...
  2. X5 E53 (1999 - 2006)
    2005 X5 w/4.4l N62 engine I had an issue with oil loss due to the alternator bracket gasket giving out. That has been repaired, but the engine was running very rough. Codes pointed at VANOS so we cleaned the VANOS solenoids, which improved it quite a bit, but not enough to make it drivable. So...
  3. E90/E91/E92/E93 (2006 - 2013)
    Hi all, Today i decided to to the following on my E91. I replaced: Valve Cover Gasket, Eccentric shaft sensor and seal, Valvetronic motor seal, spark plugs and coils. The job itself went very well aside from your typical struggles with wrestling the valve cover off and putting it back on and i...
  4. 7 Series - E65 / E66 (2002 - 2008)
    Hello, this might be a long shot. I replaced my valve cover gaskets and one upper timing cover gasket. I watched a few videos and I'm also very mechanically inclined so I figured it wouldn't be too difficult. I was wrong. First I'll start of with when I pulled the valvetronic motors out they...
  5. 1 Series & 2 Series
    Hi all, My car was rough idling, and was rough between 1500rpm and 2000rpm when driving so I put my code reader on it. At first it was showing vanos intake 2a83, 2c55 oxygen sensor, 2f08 intake air temp signal. I changed a vanos solenoid. And the car was still lumpy. The car then got...
  6. General BMW Questions
    Hello everybody. I have done a lot of maintenance to my E92 over the past few months, and I haven't reset the ECU (as far as I know) at all. I have replaced VANOS solenoids and changed the oil multiple times. I have also changed the air filter and replaced MAF. I was wondering if any of these...
  7. E90/E91/E92/E93 (2006 - 2013)
    backstory: car used on Turo and checked with INPA reader all the time. car gets side swiped and pushed onto curb (passenger side) and a week later codes start firing off. Basic code reader says misfires in 4,5,6 bmw dealer scans and sends this attached invoice. 2 questions: a) can an impact...
  8. E90/E91/E92/E93 (2006 - 2013)
    Hi guys, newbie here! I am having an issue with my wife’s BMW. It’s a 2008 328xi 3.0 litre inline 6 engine with 219,000km I guess I’ll start from the top. Last summer the car kept throwing an oxygen sensor code (can’t remember which one) I reset the light and it would stay off for a long time...
  9. E39 (1997 - 2003)
    i have a 523i 1997, non TU M52, with 110k miles i noticed sometimes at around 4000 rpm to like 5000 it hesitates, loses power, and then suddenly at 5500 it has a burst of power all the way to 6500, and also when i start it after sitting a while, it cranks quite a bit, cold starts are fine, but...
  10. E90/E91/E92/E93 (2006 - 2013)
    I have a 2011 e91. Looking around it would appear there was a recall issues for the Vanos bolts. Mine have failed as confirmed by the BMW service department. They not only need to replace the unit, but remove the oil pan to remove the bolt fragments. I contacted BMW NA and they told me there...
  11. E90/E91/E92/E93 (2006 - 2013)
    Hello, so randomly yesterday, I took my 2008 328i out to get food. Upon driving about a mile I experienced a the car stuttering and a great vibration. At this point i knew something was wrong so pulled over to find my scan tool which, i realized I left at home, so i headed home. I eventually...

  15. E90/E91/E92/E93 (2006 - 2013)
    Hi everyone, my e90 (2008 328i) was giving me the exhaust solenoid stuck code, so I decided to service both the exhaust and intake and just replace them. I swapped them out with new ones and gave it an oil change, started the car and the car would have a lot of rpm jolts and serges. I then...
  16. E90/E91/E92/E93 (2006 - 2013)
    My car will start perfectly fine then after a few seconds it will either catch a sputter or a high rev and drop back down to about 600rpms, however after this happens my car then develops a weird diesel like ticking and i have a engine code. Generic code comes up as P052b once i placed it on a...

So, a few months back my valley pipe started leaking so I decided to take that DIY and do it in my garage, I am pretty knowledgable and handsy when it comes to cars. Along the way, I also changed the backplate that is...
  19. E60 / E61 (2004 - 2010)
    Hello, So here we go... I have a 550I 2008 70K Miles. I changed the VANOS solenoids, purchased SMP from Rock Auto. I stupidly switched the harnesses on bank 1, and my car was erratic. I drove for a little like that, because when i pulled off to test, it wasn't all that bad, thought oil just...
  20. E60 / E61 (2004 - 2010)
    Hello, I have a 2008 E60 N54 with 220,000 miles. A couple of months ago the car basically tripped out on the road (all warnings went on, screen went black, etc) after the weakest start it ever had and went completely dead. My shop replaced the alternator and the battery. On my may home from...
