Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
Hi, I'm Chad ,Welcome To JustAnswer, I'm reviewing your question and I will be be posting a replay ASAP
the most possible causes is the ABS pump itself based on my experience on those xk8 ,especial if you let it set and come back and everything went back to normal.
but testing is needed since the system consist of several sensors other then then the pump, you need a diagnostic scan with a jaguar scanner or equivalent to retrieve the fault codes from the abs system, just a simple code reader want do since it can not communicate with that abs module .
