    Hi, My partner has a 4.8l V8 non turbo X5 which runs great except that on colder days it takes 3 or 4 goes to start. Has been serviced recently and no issues were reported. Any ideas about cold start problems? Thanks for any help.

    Hello, I've started experiencing this problem about 2 weeks ago, whenever I start the car in the morning and try to turn the wheel it produces a massive screeching noise. The thing is that the noise usually is no longer produced when the car is running at operational temperature, just when it...

    I am hoping someone can tell me what this noise is. I think it may be a dying alternator but I am not sure as I haven't ever had an alternator die before. The noise happens on a cold start and starts to go away as I rev the engine and it heats up. https://youtu.be/rS5rfbQNanw

    I recently purchased a 2000 328i 5 speed with 170,000 miles. I am not sure if the fuel pump has been replaced by any of the previous owners. The car is suffering from a no start condition in the mornings and after it has sat for long enough to cool down. After I turn the ignition to position 2...

    I own a BMW 323i 2011. My car has been parked outside in the winter for about 2 weeks now in -25 celsius weather since the garage was occupied, when I tried starting it about a week into the cold weather to put it back in the garage it would not start on its own or jump starting it, so I assumed...

    Hello all. I'm brand new to the e90 game. Just picked up my first - a 2007 335i 6 spd. Car was a one owner, has 113,000 miles on it, and has a ton of maintenance done by PO. Here is a clip from a cold start. I have this high-pitched whine, but it's only on a cold start and it goes away...

    Hi guys, I think its time I enlist your help for this problem. My 92 E34 M50 still has problems starting only when engine is cold. It cranks and cranks but does not start unless I play with the gas pedal. You would think its a fuel pump issue but it too has already been replaced and car works...

    Hello, I recently bought a 2010 335D. 400 miles after I bought it an SES light came on. It was something to do with Injector. I had that injector replaced, 15 miles down the road the light came back on. It was too long after this, the first start of the day it started sputtering a little bit...
  13. 7 Series - E65 / E66 (2002 - 2008)
    Occasionally, especially on colder days, the car would misfire right on startup. The RPMs fluctuate up and down, and it gives me a "Engine Malfunction" error and says in the idrive that damage to the catalytic converter is possible. If I shut the engine off and restart it after about 30 seconds...
  14. E39 (1997 - 2003)
    Started my 2002 E39 with 125K on it this morning. It ran super rough and shortly threw a CEL. I immediately thought it was a bad ignition coil as it ran exactly like my 330 did when a coil failed. I was surprised to see that the OBD-2 code was P1620 MAP cooling thermostat control circuit...
  15. E90/E91/E92/E93 (2006 - 2013)
    So today I started the car and everything was fine. I started driving it after it was warmed up, and drove for a few miles. Then the red transmission malfunction indicator popped up, and it felt like the car was not changing gears. I don't really know too much about cars. I pulled into a parking...

    I have a 2009 328i xdrive and ever since i changed my oil to 0W-40 I've had problems. It has a rough idle and when i'm driving and press on the gas the car shakes and drops in rpms and then returns to normal acceleration. I've been told the MAF may need to be cleaned since i just had it...

    So everyone reading i am looking for some help. I have had a problem with my 2009 bmw 328xi, anytime it is cold outside (generally in the mornings when i go out to my car) there is a loud clicking/clacking noise coming from the fuse box, anytime this is clicking i have a substantial loss of...

    I live in ohio where the temperatures have been reaching fairly cold at night (35f-15f). This winter will also be the first winter i drive the car (2008 335i sedan). I don't believe it has ever seen a winter before me either. That being said, for the first time a few days ago as i was leaving...

    Sorry this is so long but this is basically me documenting my experience with replacing my 330i battery. Its not a DIY example nor am I entering myself in the registering vs. coding debate lol this is literally just my thought processes, experience and results to help others who would like to...
