Not a good sign for an APR tune, car only had 6k miles and 300 of those on the tune. Some are speculating that it could be a factory issue and that VAG is constantly revising the factory turbos. Definitely a reason not to get tuned during the first couple thousand miles, especially with a new platform/engine.
