Td1 flag

[A6S]

With all this chat about remaps and chip boxes I was wondering is there a way to see if the car has a td1 flag? I have access to vcds and other diag tools, is it a case of checking certain bits on certain modules?

It doesn't really work like that. Audi send the data to the mothership and if variances are found it sends a flag back. There are 3 flags

So there's no way to tell if you were buying a 2nd hand car?
Can the dealers reject a trade in or lower its price if it's flagged?

You can find a flagged one but it will only be flagged if audi have done it if that makes sense.

A lot of audi dealers will not accept modified cars. When i traded in my RS4 the contact specifically said the deal was subject to it being checked for engine management changes.

So if you're thinking of buying used, can you ask your nearest Audi dealer to check a cars reg to see if it's flagged I wonder...?

Yes. Remeber this is a specific action. It doesn't just pop up when you get the oil changed at at an audi dealer. Its normally done on trade ins and to reject warranty claims

That's what I was thinking. I'm quite friendly with my local dealer so I don't think that will be a prob if I was gonna buy one.
I always thought it was stored on the ecu somewhere

It is once it's flagged.

If you never take your car to a dealer for servicing after a remap then it will never get flagged.

Car gets flagged even with VCDS mods when dealer attempts the software update. Basically Audi's VAG soft checks the car's config against what it supposed to be. It flashes the car with the update wiping the VCDS mods. In the same time it sends a flag yo the central evidence system. There is a thread on audizine or some other forum with the screenshot of how the flag works. I have only 3 VCDS mods and I disable them when I go to the dealer.
