I work at a VW store, and any ECU alteration throws the TD1 flag and is grounds for a warranty claim denial by VW if the issue can be connected. The dealer has no way to hide it or force VW to honor a claim, even if they are the ones who installed it.

Now, APR has just recently put out a flash that dealers can do in accordance with VW that does NOT void the warranty, but it's nowhere near as aggressive as their Stage 1, and my understanding is going to be well over a grand.


EDIT- It's called APR Plus.
