I am picking up a 2000 S Type tomorrow to replace my knackered XJR. When on the test drive, the car ran very well but at a set of traffic lights the engine management system warning light flashed on and off twice. There were no problems with the car and the warning light didn't flash again. Was it because the car was cold? It had been sitting on the forecourt for a while. Am panicking, urgent help required before 12.00 GMT.
Cheers
Richard
