There's two extreme opinions here: cover nothing, and cover everything.
In actual fact, it falls somewhere in the middle. The most expensive failures are what we most want covered, and they are the least likely to be covered.
Most important thing to keep on mind: Dealership service departments want you to maintain a factory warranty. Full warranty cars bring them business for everyone little squeak and rattle. Non warranty cars might not show up until there's a fire.
Servicing major failures and billing VWOA is a dealership service depts best case scenario for profitability. They're incentivized to receive cars that need repairs, which is why they started selling aftermarket software, and tuned them aggressively... which is why VWOA started encrypting and keeping track of the number of times a particular vin's ecu has been flashed.
Stasis tunes for audi were literally sold as "Tuned with full warranty so long as it is maintained by the dealership you bought your car from. A one stop solution. RS line performance at 1/10th the cost to you" etc etc. VWOA found out about it by just analyzing anomolous patterns of part failures, and googling dealership names. Vw/audi implemented the same ecu flash count program that BMW had.
VW won't cover major failures without a scan. If it's something that went wrong with the OE equipment, then they can learn lessons and fix manufacturing processes to waste less money in the future. If you've altered the parameters of how the OE equipment operates, there's nothing for VW to learn. You know better what software to run on the car, so obviously you know better how to repair it.
If it's a "push comes to shove" scenario, you just can't push as hard as the largest auto maker's legal team, and it's laughable to think they'd let you.
You will not wind up as aftermarket software's Rosa Parks of warranty coverage.
Pay to play. That's the system we have now.
Fuck the system. BMS JB4. (marketing gold, right there)
But anyway, dramatic word walls aside.... Don't chip the car before knowing you're going in for anything that could potentially be a major warranty repair.
That's like taking your driving test immediately after taking a half shot of scotch while wearing a "Fuck the DMV and their teet suckling commie labor union" t-shirt. While it doesn't technically mean you won't pass, it actually definitely means you won't pass. Lol.
