Here's the problem:
My 08 M3 stalls only on right turns. It doesn't matter if the tank is full of gas or not. Just had the fuel pump replaced about 6 months ago. It was running fine until now. It just started "bogging" when I turn of the car. I have replaced the battery and checked the connections to the battery. That only seemed to help for a few days. Then it starts stalling on right turns again. Also the grounding wire is secure and good to go. Please help!

 

did you allow your ecu to re-learn idle after unplugging the battery? do this -;

unlug the battery
leave it for a few mins
connect it back up
jump in the car, turn the ignition to "ON" leave it for a minute
turn the ignition to "OFF" leave it for a minute
start the car normally, let it run until it gets to "working" temp or cooling fan kicks in(15ish mins in 10c weather)
turn off all the electric bits, lights, ac, radio etc and leave it running for another 5 minutes.

and that should sort it out.. if not, you might need to clean your throttle body with TB spray/cloth(carefully) and re-do the above!

make sure your battery is disconnected when messing around with throttle body!
