Hi guys wandering if anyone has had this dilemma, car put itself in limp mode (didn’t know that existed) took it to a garage and they plugged it in and it was saying air blockage, so they did a carbon clean on the dpf and sent it to a specialist, the specialist said everything came back all clear. The garage spoke to jaguar and jaguar told them to disconnect the battery and touch the terminals to hard reset the ecu. The car was fine for a few days but then it did the exact same thing again, left it overnight and now the car is fine but I feel it’s only a matter of time before it does it again, car is a jag xf 2.2 diesel 14 plate, any help would be great guys
