    So my car has been stalling when it idles. I finally ran codes today and got back P0102 Mass or Volume Air Flow Circuit Low Input. I noticed my MAF is chipped on the top where the wires connect to it. Could my MAF be the cause of all of this, and just need to be replaced? If not what else could...

    Hi everyone. I have a 2008 X3 manual transmission, 3.0. My Mass Air Flow Sensor is causing the service engine soon light to come on. The reading when you hook it up also says cylinders 4, 5 and various are miss firing. Once I get out of first gear, the car runs like a top it just at idle and...

    Hi, I have a 2001 320ci with maf problems. Runs rough like its going to stall at start up. Removed maf and it runs better so I guess i need a new one. my question is, if i buy a new one do i need to get it reprogramed on a 2001 or is it just plug n play? Thanks in advance.

    My car began to have a rough idle one morning and now stutters when I drive. It sounds like I can hear air or a puffing sound when idle. Reminds me of a bad muffler but not as loud and comes from the front . Can anyone give me an idea as to what these symptoms may be?

    The local BMW garage is stating I "may need" a new MAF sensor and they're quoting me a price of $700 plus... I noticed a replacement MAF sensor online for my 2006 X3 is roughly $300-$400; can I replace this myself? The garage is stating the vehicle will need to be "reprogrammed" after installing...

    Hello! I'm having difficulties pinpointing a problem with cold starts. The engine will take 5-7 seconds before turning over. I've hooked up a fuel pressure meter directly to one of the hoses and it stays steady at 40psi. The plugs have been checked, injectors cleaned, fuel filter...

    Hello I was changing my airfilter on an 2002 320i when I went to disconnect the wiring harness, the metal clip flew off and is no where to be found. I was wondering if anyone know where I can get a new one, besides the dealer. This is for the clip that secures the wiring harness onto the mass...

    I was experiencing some issues with my 2003 530, 120,960 miles, not responding very well when accelerating from a complete stop. The car seemed to hesitate and in some instances completely shutoff and then the whole dashboard lite up like a Christmas tree. So, I took it to the BMW Stealer and...

    I posted earlier today, but was a reply to a thread, so here is a new thread on this. My 01 E-46 with new head gasket runs great, but turned on the MIL (service engine soon light) and has code P0102, Low voltage at Mass or volume Air flow sensor. I checked all the hose clamps they are tight...
