Wondered if anyone had the same problem got a Jaguar XF 3.0 diesel 2010 keeps going into limited performance mode had one plastic intake changed as it had a crack but still have the same problem took it to a garage and they said they think it’s DPF as it’s blowing out the side of the gasket now aswell anyone else had the same issue. With the DPf being blocked, the car has also done 140,000 now so is likely it could be blocked many thanks for any help
