Hi,
I have a problem with my car, it takes to long to start and when it does I put it in to Drive and press the accelerator the car stalls, it feels like the engine shuts off completely but when I take my foot off the accelerator pedal the car stays at idle.

Any help will be appreciated,

Thanks!

Sounds like a problem with the MAF. Usually it will idle just fine, but when it is under load, the engine doesn't know how much air is coming in so starts to go crazy. The meter for the M30 (since it uses a mechanical version) may be jammed/stuck. Could also be a throttle position switch. Something along these lines...

That's my best guess?

Fuelfilters and Fuelpump in the tank are ok?

Fuel filter is new, haven't check fuel pump yet. I need to know where is the fp relay? How can I check the MAF?, electronically speaking, the flap seems to be working fine.:dunno:

Thanks.

I am not so familiar with the english shortcuts what is MAF?I think it is LMM Luftmassenmesser in german?You can go to a dealer and let them put the car on the computer.

Then all faults will come out but I had with my 540I a lambdafailure according to the computer but it was the fuelpump that was the error.

And you can't check that with the computer.I think the relais under the backseat?
