Hello. I have a problem and you guys can probably help me. I have a Mk.2 GT 1.8l 8V with digital speedometer and mfa display. All the functions seem to work just fine but there is something odd with gas consumption reading. It always stays between 39-45 l/100 km, it works, but the reading is totally wrong. Is there any way to fix this thing. I alrady replaced the main computer but nothing has changed. Thanks for help.
