Also the reason why no one has any hard answers on what triggers a TD1 is because its not suppose to be open. Its a tool for VW to use to detect aftermarket tunes. If the algorithms they used for detection are published then tuners can just get around it.
Sucks for tuners. But makes sense for them.
But, people who have had TD1 flags raised have been saying that it can be anything thats different from stock settings.
I.E someone used Vagcom and activated needlesweep on their Audi A3 in the UK (audi-sport forums) and they had a TD1 raised and checked against their "instrument cluster". Ridiculous sounding but apparantly it happened.
Thing about TD1 is its not just end-all of warranty, if a warranty issue arises its "supposed" to be investigated to see if whatever raised the flag is causal of the issue, and is judged case by case basis rather than. You have a TD1, peace out warranty replacement.
