Common Failure

Jaguar XK8 Engine Performance Limited - Misfire on Multiple Cylinders

You may be experiencing symptoms like non-start or hard-to-start conditions, rough running, and 'engine performance limited' displayed on the instrument cluster. When scanned, fault codes such as P0351, P0352, P0353, P0354, P0355, P0356, P0357, and P0358 are often present within the engine control module. These symptoms and faults may disappear when the vehicle is cold but reappear once the vehicle reaches running temperature. If replacing the coil packs hasn't resolved the issue, this could be because the ECU has stopped sending signals to the coils.

These issues are indicative of an engine control module failure. At VCUS, we have developed a solution that eliminates the manufacturing defects and replaces worn-out components with upgraded versions. We confidently provide this repair with an unlimited mileage, lifetime warranty for your peace of mind.
