Does anyone know how I can reset the service indicator on my A3? I've just had a service and I've tried what it says in the manual - pull the button under the speedo for a few seconds and then again to reset but it doesn't work, I still have a spanner showing all the time. It says the number of miles to next service is -8600, so I'm guessing it wasn't reset at the previous service either (before I bought the car).
It says in the manual that it can't be reset if there is a priority 1 fault detected? How can I tell if that is the case? Or do I have to take it back to the garage?
