I picked up my new 2021 etron this week and within 48 hours it is back at the dealership(so, so disappointing 😞) So I was given a loaner(that was not an etron) as I waited. The diagnosis: (1) wheel speed sensor failure and (2) coolant pump/valve failure. Parts are coming from Germany so I'm looking at 2 weeks until the pump replacement part arrives. I asked for a new car but that didn't work. Anyone here on this forum with experience with a similar problem or advice in how to navigate Audi customer service?
