If running a tune, is it possible to flash it back to stock before dealer service and not get flagged TD1? What else can you do - other than no tune- to prevent ending up without warranty through TD1 identification on your VIN?

Thanks

It can be done.

Make sure no Audi techs plug your car into their big bad diagnostic equipment while you're tuned. This makes service very difficult ;-)

Best bet, from what I've read, is to flash back to bone stock (usually have to go back to your tune's dealer or send off your ECU), then take to dealer.

Or stay away from tunes altogether. Which is no fun, right?

I have seen it on the diesel world, they can tell the vehicle was tuned either way. They will be able to see when the last time the ECU was flashed. I don't know that you will get flagged for sure if you flash back to stock, but if there are issues and they see the irregularities in data, it will get you flagged for sure. I can imagine that audi can do the same. You can flash back to stock and see if it gets flagged.
