Our local Audi dealership sent it out for TACS testing, which is what other dealerships have done according to others on this list, so I doubt another dealership in our area will do anything else.
As to selling it, we only have 22K miles on the car and it usually works well, it is fully paid off, and we only use it around town in EV mode. We have no desire to purchase a new vehicle. If we replaced it, we would likely buy a low cost used BEV. Our 2018 Tesla Model 3 works perfectly, has had only 2 minor issues (repaired under warranty: glove box replaced and running lights on driver side replaced), and we are at 45K miles. We will keep it forever.
Problems:
1. Decreased electric range.
2. Starting failing once every few weeks, even though the brake pedal is fully depressed. We have to turn it off and push as hard as possible again, so that it starts. It does not occur all the time, and the dealer was not able to make it happen in their testing.
3. The car occasionally changes to battery hold setting, even though it is ALWAYS set for EV. Turning it off, doing something for 10 minutes or so, and it starts up in EV mode again, so there is a software flaw, but our dealer was unable to get that to occur during their testing either, which is not unexpected, because it usually happens only once every 3 months or more.
4. Audi USA has poor customer service after you have already bought the car. Tesla service has been excellent. Our local dealer has tried to support us, but has been left hanging by Audi USA, so no battery pack replacement, even with California’s 10 year 150K mile PHEV battery pack warranty.
Final solution is to contact the CA Attorney General’s office.
