Hi, New to the Forum. Just bought a 2011 C70 II D4 Geartronic (with 51K miles) in the UK and planning to take it to France where I live next week. I've noticed that the drive selector has started to jump when selecting Drive from any other position. The problem is not apparent at start-up, only when the car has been running for about 30 minutes.

There's no major work showing in the service history, no timing belt etc or Geartronic oil change/flush. Would an oil change/flush be the next step, are that other components that could be changed/changed at the same time? Thanks in advance for any advice.
