Durametric DME "Total Distance"

Recommended Posts

My 2004 986 has 32,571 miles on the odometer. It had 29,861 miles on it when I bought it. Durametric reports the following info:


Instrument Cluster K21    


VIN      WP0CA29874U62****

Total distance      6215            


Bosch Digital Motor Electronics Motronic 7.8    

Number of ignitions range 1      2581 / 1104.8h

Number of ignitions range 2      0 / 0h

Operating hours counter      1126.2

Vehicle Identification Number      WP0CA29874U62****

Data version      0041610046303404

Type ID DME control unit      __986US31

Order type      986310

Country code      C2

Transmission type      - :)

Transmission number      A8605

Interior equipment      AA          


Doing the math on the hours gets 29mph. But the instrument cluster "Total Distance 6215" converts to only 3,861 miles. I've driven the car 2,710 miles since purchase. That leaves a difference of 1,151 miles.


Does all this mean that something in the instrument cluster was changed? Or, what does this mean?
