Bought from a forum member without thinking and I need the T87A like anyone with a 2017+. Basically all this is good for is if you have a 2016 A8 and want a trans tune but want to be able to swap back to stock if you have to go to the dealer for a warranty issue (shudder issue and you don't want a trans tune blamed maybe?). $50 shipped.

They will know you have to have the TCM registered to your vin and unless you have a shady af dealer who likes mods your not gonna be able to hide it.

I would assume you'd program your VIN into both just like when you do an unlock through HP Tuners with a 2nd TCM and you'd just slip the original one back in if you go to the dealer.

Mileage won’t match between the modules, I’m assuming...
