Trip computer reading low miles
My 1.9JTDM's trip computer has gone silly just after the car was in for a service .. though I really can't think how fiddling about in the engine bay could cause this: The mileage it counts up is low compared to actual (as reported by the odometer) by a factor of 5/8. There's been some threads on this before but no answers to the mystery:
It seems more than a coincidence that 5/8 is the conversion factor between miles and kilometers. If both devices get the elapsed distance from the same sensor then it tends to point to a software problem - which I really would like fixed as it makes my mpg look terrible! Has anyone any insight into the cause?
Edit: Found another link with lots of responses .. it seems I'm not alone. Mine is a 55 car so perhaps it's got some bits from those Alfas on the ship that hit the rocks (I'm not 100% convinced the story is kosher though!)
