    Hi all, long time no post. I have basically parked the car for the last couple years but dusting it off and getting back into fixing it up. Pretty much limited driving the car over the last couple years as I had to have the drive shaft rebuilt as the joints were having issue tearing up the new...

    Yesterday, I installed new rotors and brake pads on my 330i. After lowering the car and taking it for a test drive, I noticed something was wrong. When I turned the car on, it sounded fairly loud especially when I accelerated. The car was also sluggish, and stumbled. I went to go get gas, and it...

    Introduction It took me a long time to understand fuel trims, despite excellent videos by 50skid and excellent posts by JFOJ. I think I have a handle on them now, so I thought I would try to explain them as I understand them, and either help someone and/or get corrected. Here is my shot. Theory...

    2002 330ci 5 speed w/ 205k miles Alright I've got an interesting one today. While almost home from a ~50 mile drive on the interstate, my car suddenly lost all power, and stalled when I pushed the clutch in. I was at about 1/4 tank of gas but it acted like it ran out. I checked the oil, made...

    Hi, can anyone help. I've purchased a new fuel pump by Bosch. I checked part numbers on real oem using the vin and ensured the specific numbers matched yet the new pump is significantly smaller as you can see in the first picture. The car is a 2002 330 ci. My question isn't so much what do I do...

    Hi all. So the fuel sender attached to my fuel pump is malfunctioning. I'm getting the usual symptom of my fuel gage reading completely wrong. I ran the built-in diagnostics at the instrument cluster, and my numbers confirmed this (left unit reporting fuel, right unit reporting a constant 13L...

    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...

    Hey guys, I searched the forums already and saw some issues similar to mine but nothing 100% similar. About 4 days ago, I got a P0102 code. I decided to grab some MAF cleaner and hit my MAF up a little bit and clear my code too see if that fixed it. So no biggie there. Following this, about a...

    Hey guys, so last week I returned from a trip and had my car sitting outside for about 2 weeks. When I came back, I turned the car on and saw that the gas gauge was reading empty, but my display had four hash marks. I knew for certain I did not leave my car empty. After getting gas and putting 4...

    Hello all, I have an '01 325i (12/00 production) which is currently experiencing an issue with the fuel gauge. After a 600+ mile drive over the holidays, the fuel gauge needle started to fluctuate and slowly drift around while driving or even at idle. This was intermittent and occasional at...

    Hi. I have an E46 325i that is "idle-hunting" The idle goes up and down. I've replaced and checked alot of different things to fix this such as Vanos seals, DISA-valve, intake boots, ICV and some more parts, but I haven't been able to solve it. Now I'm suspecting a bad fuel-pump. But...

    Started the car up new years day after a night of sitting, it didn't sound or feel like the normal startup, I could tell the cold weather had some effect on the battery. The battery light came on and went out after driving for a couple minutes. Then I noticed that my radio had shut off and all...
