My 5 month old 2.0 TDI S line has been in the dealership for almost 2 weeks! It started as an intermittent fault, poor idle not always starting first time Then while driving along the motorway I thought the car was about to take off. Road side assist came out and said it was misfiring and got it towed to the garage. They have so far replaced an injector the fuel pump and are carrying out some 'tweaks'. I don't feel the garage is keeping me fully informed! Has anyone heard of any problems like this with these engines?
