First of all i'm new to this forum so hello everyone!
I've found a 2010 S3 with S-tronic I really like but when I was out on the test drive I noticed when changing gear there was quite a bit of lag. Best way I can explain it is flat out in 3rd the gearbox changed to 4th and it took about half a second for the turbo to kick in again. Surely at 5k rpm the spool should be nearly instant with that load? I've watched a few youtube videos and it seems instant.
The dealer says they will fix it but has anyone heard of this before or got any ideas what it could be?
