How can you recall secret menu checking real kms or miles in car on 2000 Jaguar S-Type V8?
It could be in the engine computer... but your Jaguar Dealer
would need to access it, IF his computer has any forensic ability.
I know that Police accident investigators can go into the computer
and access information about the way the vehicle was being driven,
speed and so on, immediately before an accident... but I think the
computer needs to be removed from the vehicle and it's memory
tapped using special forensic tools.
Speed freaks beware!
