Anybody know how to reset the service display on the og1 service.

QG1 that would be variable, only through VAG Com or dealer equipment, usually done by resetting channel 2 on 17 instruments to 0.

Switch off ign ->press trip reset and hold ->switch ign on ->release trip button ->turn clock adj button to the right, should reset.

If it doesn't do the above but hold the trip down while turning the clock one to the right. hth.

That will revert the car back to fixed service (10k miles) not the variable it is currently on,

fordfan is correct it needs either VAG-COM or dealer equipment to reset it on variable service.
