Had my s3 for about 1 month now, i was happy with the speed and acceleration but it didn't have quite the pace i was expecting.
Cleaned the maf the other day....had no effect. Cleaned the throttle body and reset ecu yesterday and OH my god it shifts now. It feels like a different car, even the slightly eratic idle has gone.
If anyone has bought an s3 recently and has not done this 10 minute procedure i highly recommend doing it.
Really need to upgrade the suspension now though.
Thanks for the posts on here that helped me to carry out the simple cleaning job.
