I've been having a problem with my 3er Golf TDI (1Z) recently. When I need to accelerate a bit in certain traffic situations, it almost stalls, doesn't respond to the gas pedal for about 2 seconds, and then revs up smoothly again. This only happens when I quickly release the clutch pedal and press the gas pedal at the same time. Otherwise, there are no other issues. Could the LMM (lambda sensor) possibly be weak? VAG COM is present.
Thank you for your help,
