Does anyone know a good source for these? I'm seeing "Genuine BMW" on ECS for $350, which feels obscene but I guess I'll do it if that's what everyone recommends.

Hello. I have a problem with my e46 320ci. The car wont idle and it feels like it doesnt have any power at all. It also runs very rough when i press the throttle and the rpms jumps up and down. I diagnosed the car with an OBD scanner and it said it was a bad mass air flow sensor so i changed it...

Hi guys, I've just picked up a e46 325 Compact in the last month as a bit of a project. I've been wanting to learn how to work on cars and I also needed a bigger boot as my last car was an MX5. I got this car cheap and it came with a couple of faults which I've been working through. I've got...

My 325ci has had the p0411 code for a while now and I'm trying to fix it. I already checked to make sure that the pump is blowing air on cold starts. I just cleaned the secondary MAF and the connectors and the secondary air filter looks fine. All the hoses are in good shape so my problem must be...

I'm new to the forums I tried searching but no luck. A little help please my MAF may be going bad but don't know. Coming to a stop my cars rpm will go up and down between 500 and 1k rev. Sometimes when I hit the gas it shuts off I unplugged the MAF and seems to be okay then I plug it in and the...

I have recently been having problems with my 2003 330ci. It seemed to be a transmission issue, as the car seemed to be slipping between shifts, but I took it to a transmission shop, and they told me that the transmission was fine. The car has been shooting codes for a while now, and they all...

Hey guys, quick question, is there an aftermarket Mass Air Flow Sensor that is actually worth the money? I know its a pretty crucial part of the car (04 330Ci) but im also on a budget, anyone had any luck with a cheaper alternative to the 350 dollar OEM replacement?

So i have an issue with my 2000 323Ci. The car once in a while idles a little odd (goes up and down but has yet to stall) However driving it for a couple minutes it is alright But it does not happen all the time but i would like the fix it before it becomes any worse. I get the following...

:eek:Hey the little wire clip that holds the MAF electrode to the sensor bounced off when trying to take off the Massive Air Flow Sensor to clean it....Can you help???? Where Can I get one? :yikes:Its the little silver clip on top of this electrode connector held by the hand If someone...

Hi im driving a 318Ci 2002 Manual that has developed the 'rev hunting' condition. Ive been all over the net looking for help/advice on possible fixes for this problem but there seems to be no sure fix as the problem varies depending on the symptoms? With my car it struggles to start but then...

Hi All, I have been suffering from power loss for a while - i put my foot down and its like driving a slug and expecting acceleration... I have been reading a lot on this problem as many 3.18i owners seem to have it. One of my major suspects is the MAF after trying/replacing some other...

I had a CEL and Red oil light and was told it was the MAF and the oil pressure sensor. Replaced the OPS and all is well except for now I get a yellow oil light at start up and then it goes off after a few minutes or so. Was told it was a oil level sensor. Had that replaced. Still comes on...
