hi i had a guy come and do a diagnostic on it he said it was the fuse box under the glove box. its a 1.4 v8.petrol and its a 2002. just wondered if it has to be the same key as mine as i am not sure what the different keys mean. car went into eco mode tried to reset it but no luck. he said its the body control module if that helps. any advise help would be very much appropriated. thank you.
