I bought a used 2009 c2s pdk with 17K miles on it. The car drives beautifully,  except in the m-mode, when I shift from the 1st to 2nd gear, the rpm would go up to 4K before the 2nd gear is engaged. I am used to(2003 tiptronic)  change gear around 2500~3k rpm, but this c2s seems like having a mind of its own and takes the rpm to 4k every time. This only happens from 1st to 2nd, all other gears are fine.  Is this normal? Should I have any concern over this? Thanks in advance!

I think the first thing to do would be to have the car scanned with a PIWIS or PIWIS 2 tester.

It would seem there may be fault code(s) or other issues that the diagnostic routines can pick up. Even something as simple as low fluid.

Are you sure you mean m-mode? In M-mode you need to upshift unless you hit the computer max. Perhaps you mean auto-mode?

yes, m-mode, manual shifting from 1st to 2nd at around 2500~2800, the rpm would jump to 3800~4k before it comes down to a 2k's level.

I think you need to get the codes read for the PDK. Sounds like it is slipping between changes. Mine doesn't change that way. A PIWIS is best for codes but a durametric will give you codes also.

      Went to the garage, started my car, pulled out of the garage, braked to stop to check that my garage door closed (5 sec max), applied some gas and nothing happened. When I tried to change the gear selection, the gear indicator in the tachometer didn't show at all.  Pushed it back into the driveway as best I could. I have tried it several times with no luck. No fault lights have come on!!  I looked here in the forum but didn't see any postings that were similar.  Five days previous to this event, I returned from a spirited, three state sampling (1900mi) of the twistys and mountain roads, only smiles as a result.  Anyone have any thoughts?
