I have driven a 2008 CMax 2.0 TDCI Powershift for 70k miles without issue and really enjoyed this car however over past few weeks it is running really roughly. On acceleration it bumps and bangs and cannot appear to find appropriate gear. It is hesitant and "hunting". It is a dry gearbox and so should not require any maintainance until 100k plus. If I put it into semi auto it continues to rev erratically especially under pressure such as accelerating quickly, on motorways or going uphill. There are no fault codes and I am hopeful that someone may be able to suggest what is happening. thanks in advance
