Ihave a 2000 xj8 and the airbag light is coming on and off. any thought on why and how to fix?

 

You're in the wrong forum. You want the X308 forum. Even there though, you should provide people with the diagnostic trouble codes. There are generic codes for all cars and then Jaguar specific codes. SRS warnings are usually found to be Jaguar specific so you will need those codes using a Jaguar code reader. Without them, it's just guessing. Again, though, go to the correct forum.
