I have a Jaguar XJ 2001 model. The engine does is not running

Customer Question

I have a Jaguar XJ 2001 model. The engine does is not running smoothly and I think it ha to do with a RESTRICTED PERFORMANCE message that comes up on the dashboard along with the ***** *****ghts. My mechanics have cleaned the nozzle, fuel filter and pump - it goes away for a bit and comes back again. What could be the cause?

Did the mechanic scan the vehicle for the stored fault codes? If so do you have the code numbers?
Customer: replied 2 years ago.
I will ask him (for the codes) over the weekend and revert to you, please

OK yes let me know. It could be a number of engine sensors or systems that can cause this.
