Hello, I have a tricky one on my hands if anyone could help. My e46 wants to start and die when I’ve already ran it for a while and the engine is heated up. I can’t even keep it going with the throttle. I know the check engine light has been on the entire time I’ve owned the car, but I never...

Hi Everyone! So i just went out and drifted and had some fun for a bit on the snow, i span around on the ice and my car turned off. When i went to start it it started rather unusally, it took him 2-3 sec to start up and then it was running odd like something is clogged or something like that...

Hi guys, new to the forum but I've been lurking and reading for a few weeks. I've just bought an 2003 e46 318i, and I'm having major issues getting it to start. When I got it, it was throwing a cam sensor code - I replaced both cam sensors, and the crank sensor - but still no start. I turns...

Hey All: So new week, new problem :p My set of keys to my e46 died (or so I think) usually I put the key into the ignition and the car doesn't start whatsoever. So most of the time I sit in my car turning the key on and off for anywhere from 3 turns to 5-10min. The car always eventually...

Hello, My car (automatic 2001 325i, my first car/first bmw) was sounding rough, like an old boat. It was driving fine, just sounded terrible. Reading the CEL, I had 2 misfires, so I replaced the misfiring coils and all the spark plugs because they were overdue. This is where it gets fun- it...

My '04 325xi won't start. Jump starting did nothing nor does charging the battery. All other electric seems fine. The starter does not engage when i turn the key. Had a few slow start ups in the last 2 weeks but assumed battery related.
