Hello there wondering if anyone can help me, I have a Seat Leon 1.4 TSI and I have been having performance problems for example when driving up hill it looses power and the car jerks, I have taken it to a mechanic once and said my Cam shaft position sensor is faulty, so I have replaced that, but the car is exactly the same, have checked the fault codes which read 00769 (which I think is either spark plugs, ignition coil or injectors) and then this one 00308 I can't find anything online about it. PLEASE HELP!
