Went out in the car tonight, and straight away it felt slightly odd. When spooling up from low revs (when planting your foot quite hard) the car seems to surge almost too hard. Almost if its over boosting. If you are doing 50-60mph in 6th and floor it by comparison you don't seem to get anything like the surge I used to. However if I drop a gear it is quite a bit better, but somewhat inconsistent. Seems to be no issue with getting to high speeds, and no apparent misfires etc... Only other thing I have noticed is a fluttery sound coming from the drivers footwell. Aiming to get the car on VAGCOM tomorrow, but any thoughts from anyone as to what is sounds like. Car is running 98RON, not long serviced, and a new revision OEM DV, so don't see these as an issue. Could it be MAF related? Many thanks in advance.
