Total distance travelled by the vehicle can be read from the malfunctioning 
instrument cluster or determined by vehicle service history.  

z

Total distance travelled display of new instrument cluster must not be 
more than 100 km (63 mi) before adaptation.  

z

Total distance travelled to be transferred to the new instrument cluster 
must exceed 100 km (63 mi).  

z

Adapting total distance travelled is only possible once and only in a 
positive (upwards) direction.  

z

Adaptation can be interrupted with the "C" button of the VAG 1551/1552 
Scan Tool (ST)  

z

Correcting a false entry which has been confirmed is not possible. The 
instrument cluster must be exchanged for a new one.  

z

For US models, the country code must first be changed to "Canada" 
before entering the adaptation value.  

z

Adaptation value on instrument clusters must be entered in kilometers. 
For US models, adaptation value must be converted from miles to 
kilometers first (miles x 1.609 = kilometers).
