The Drivers Handbook say it is located on the left upper front of the engine block close to the lifting hook. I have tried to locate it but so far no success. I also saw I think it was in my Chilton manual that it is stamped on the pan rail close to the oil filter location. I will try that when I change the oil.
Reason I need this is I'm sending the card to Jaguar out of the Drivers Handbook to register as the new owner.
