mine does this, i always notice when i drive off to work in the morning so it must be a cold engine thing
i've got an untouched 210 LCR with no vag com faults
I'm suprised more people havent noticed this though
Maybe its because it only happens when you accerlerate gently ;o)
I would like to hear other peoples views on this,
its when you are on a slow steady acceleration in 2nd, when you get to 2k revs it should loose a bit of power (try when engine is cold)
