I have an 05 Audi A4 3.0.

This week, while I'm driving, I notice that it goes from D to S-mode randomly. The RPM's flare up, and then it calms down after a minute or two.. only to do it again 10-15 minutes later.

Has this happened to anyone? The dealership is baffled.

Thanks!

Did they find any gearbox faults? MIL on?[/align]
