Info:
Vehicles with long life service intervals (some Audi/Skoda/Seat/VW) cannot be reset using these procedures, only cars (some Audi/Skoda/Seat/VW) with fixed interval servicing can be reset. It’s a VAG thing.
I take No Responsibility over your actions whatever may happen, you reset your service light at your own risk
If your service light wont go out on your first try have a few tries sometimes its hard to do.

Please note where “– “is shown, this means tested up to year 2002

I hope you find these procedures informative and useful.

Disclaimer
resetting your service light is not a substitute for servicing your vehicle. Obey your manufacturer's suggested service intervals
