Godiag GD801 ODOMaster customer problem:
May I ask why the Mercedes A and B CLAS 2005-2007 first changed their readings, and everything returned to normal after 2 seconds? The original mileage was 201951 km, and I changed the new mileage to 165007 km.
Godiagshop.com engineer replied:
Install an MB CAN Filter (i.e. Yanhua brand) to your car, and then correct mileage with Godiag GD801 again.
The filter will shield the communication between the instrument and the vehicle.
