It's driving me crazy!
I hope you can help with this really annoying problem.
I bought this 2005 M5 3 years ago, all seemd really nice, but the car started rough idle and stalling at lights, losing power when driving at highway since last year. Everything happened rather occassionally, and always when engine was warm and hot weather.
I took it to a garage and dealer had it thoroughly checked. Spark plugs
, cables, air and fuel filters
etc, though nothing was found.
I also changed the all o2 sensor, maf, throttle actuator, alternator with regulator, etc......
People from the garage now think it is probably the Air Flow Sensor
fault, which apparently is very difficult to find the reason.
I'm not an expert and don't really know what the problem is, but I have read a lot on the internet still no finding.

I hope somebody with knowledge of this car and experience, can give me some advice please
Thanks in advance.
