Get in writing that the dents in the undertray will not be an issue for an HV battery warranty claim in the future. In the US we have an 8 year warranty. Make them show you the voltages of all the cells are even. Ask if the car ever had a battery cell change or a whole battery swap out. My car...
Are you able to scan the car from the OBD port to see if any steering associated errors are present?
I've seen these three sporadic errors on my 2020 4 S that could be present:
U112100 Data bus missing message
U13D500 Function restriction, directional stabilization assistance
C135DF1 Steuergerat...

I've had a few problems with my 2020 4 S. Several are known issues. Heater (2X), AC servo motor failed, HV battery (Replaced with a 2023 version). Late last year the rear motor failed and was replaced, paid for by the aftermarket Porsche EV warranty. There have been many software updates along...
There was no push back from Porsche as my car was out of the new car warranty. The dealer had to provide evidence to the aftermarket warranty that the repair was necessary. They then approved the repair.
Be aware that there is a bit of different pedal behavior from an ICE car as the Taycan transitions from regeneration to the hydraulic brakes. My 2020 4 S is not as slick doing this compared to a 2026 Macan EV I had as a loaner. Your car should be current with it's brake fluid changes as the 111...
