    Hi Everyone, I was hoping to get a hand in diagnosing a cold start issue. After a few days in the garage without any use my 330xi struggles to turn on. Here is a video of the problem. This time it was pretty mild, sometimes it takes many more "cranks" before it finally turns over. Note I...

    Hi everyone, I have a M54 2003 330i. The average would be 5 degrees when the cold weather in Turkey. When the weather is cold, my car starts shaking on cold start and this situation does not improve until I turn the car off and start again. The shake is so much that I think the car is dancing...

    Good day! I hope everything finds you well, (brief history 2002 325ci) I've had the car for almost 2.5-3 years, got it at 122k miles, it is now at around 145k miles. When I got the car, I replaced spark plugs (no coils), did complete coolant system refresh, fluids(brake, tran, diff) and lots of...

    Is the air intake on the 323i more efficient then replacing it with a 3" pipe and a high performance filter? It looks like sucking the air out of a huge box instead of a pipe seems worse or am I missing something. Will it improve my performance on a 2000? This morning the ignition cranked for...

    When my 330ci starts after a few hours of non use, it makes a deep "whale" noise that lasts for about a second each time. It makes like 3-4 groans then continues normally. Very strange as it does not seem steering or speed dependent. Looked through the threads and I haven't found a satisfactory...

    Hi everyone, I have done my research in terms of my problem but nonetheless found inconsistencies so essentially I want to ask what to do next? The Story: I have a project-ish e46 sitting in the garage that I am turning into my summer daily. The car has o2 sims (which I'm still trying to...

    When my car is started cold, it makes a weird high pitched noise - I can't decide if it's a whistle or a mechanical squeal. I read lots of threads describing similar issues and it seems most are either caused by pulley bearings or vacuum leaks. Armed with that knowledge I had another look and...

    I apologize - I know there's too many of these, but I didn't want to hijack another poster's thread, and the resolution to my issue may take a different direction. I've read every thread I could find here and elsewhere, and have eliminated many of the common diagnoses for my Lean Code...

    My car's service engine soon light popped on about 3 weeks ago. It was around -10 on my dashboard. It had a loss of power/rough idle, until i shut off the car and started it up again. The light went away after a few days and came back on a week later, also very cold temperatures. I cleared the...

    Hey there. I have an automatic 01 E46 that I bought about 9 months ago. It was all fine until recently. My service engine soon light came on. When I cold start my car it will shake pretty bad and the rpms will drop and rise from 1k-3k. I'll let the car warm up a bit before driving and when I...

    I have a 2001 330XI automatic with about 160K miles on it. It is my wife's daily driver. About every 2 months we will have a cold start issues. It either idles really rough with the roughness disappearing after 30-60 seconds warming up OR it won't idle at all and I just crank and crank with...

    I bought my e46 around a month ago and have been having absolute nightmares. It's a convertible 330ci 2001 and in the morning most mornings it has been misfiring and when I press the accelerator it's very limp and sometimes just dies. I generally hold my foot until it sits at 2000 revs until it...

    So I've had a rough cold start idle since I bought my car back in January 2014. The car had 88,000 miles on it. It now has 96000 miles. I figure I inquire about this before there is any serious issue. My car has no check engine light, EML etc. When I start it up in the morning, it has a rumble...

    I have owned my 2001 BMW 330i for two weeks now, the first two days of owning the car there was no noticable mechanical or electrical problems. No more than three days passed before I learned that the Tempurature Sensor had been completley sheered off by some sort of low curb impact before I had...

    Ok, so I've been doing a lot of research on this, but I'm stuck. I have a 328i and any time the weather is below 80 F, my car does a rough idle at start. It lasts longer in the winter, but the symptoms are the same - about every 10 seconds the RPM gauge goes lower and lower, until it ultimately...

    My car has developed a problem where on a cold start the engine will idle around 1100 RPM before slowly dropping to around 1000 and then after a few minutes to the normal idle. When the engine's warm it idles normally and I've scanned it but it's not giving any fault codes. :thumbdwn: Here's a...

    I have tried to replace a lot parts for my 2000 323i and the cold start misfire problem still happens. I am very positive that the more cold the temp is (around 32F), the misfire seems worse. I got only random misfire codes, a strong feeling of car shaking, and a big smoke out of the tail...
