and how to if poss on a 2003 s3.
Via the Engine 01.
Its in kph.
Not sure if the cluster & ecu share the same reading as such on your car tbh, but the 8P 2.0 tdi has cluster mileage & ecu mileage, so if someone clocks it, the ecu will differ from cluster, ideally you need to ask RT with your engine code & an autoscan as cant be sure for all engine codes & years I'm afraid.
None of my cables retreive milage from the ecu, but I can change the milage on the cluster.
Separate names with a comma.
