Hi hope someone can help, have a 2007 A3 2.0TDi trying to reset service on the dash. Using VAG Com 704.1 all upto date, using the SRi function unable to reset mileage to next service, keeps coming up 1300miles left. The days change depending if we try long life or fixed BUT the mileage always says 1300 mile !!!!
Also tried the adaptation route, channel 2 to zero, this was on 2 which I`ve not seen before. All other as per ross-tech guides are right.
I guess Im missing something just cant see what :-)
Thanks for help.

I realize this response will be of no use to the OP given the time passed since the question was asked but I just now did a bunch of searching looking for the same info and couldn't find it. I too have a 2007 A3 and the instructions in the owner's manual for resetting the interval did not work.

So here is what I believe finally did the trick. (I say "I believe" because I tried so many different things I can't be 100% certain but I'm maybe 95% )

1. Start the engine (may not need to do this - perhaps just turn on the ignition ? )
2. Pull the reset **** to the right of the trip computer display. The display should now show you the miles/days to your next service, or in my case by how many miles you have exceed your service interval.
3. Release the reset **** and then pull on it again, holding it out until the interval resets. The display should now read something like service in --- miles/--- days.
4. Restart the car and the service warning should be gone. To double-check you can again pull briefly on the reset **** to show the remaining miles/days to service. It should be reset to 10000 miles/365 days assuming your service department correctly reset the interval at your 5k service. Mine did not and I had it done via vag-com.

I hope this helps and please respond to let us all know if it worked for your A3 also.

 

Worked perfectly.
