Thanks for the information. Audi are due to call tomorrow. We will see what they have to say. Sadly ...it is never very warm in Scotland..apart from maybe 20C in July! Other parts of southern UK are less cold and wet.Sorry to hear that NF1. But you’re not alone….globally. Audi is blaming the delay on replacement parts on the chip shortage, but they haven’t said anything about why the high voltage heaters are going out on all their EVs all over the world. Of course they’re mostly reported in cold climates. in addition to using the seat warmers, my wife has added a heavy blanket to my 2022 GT, so she can cover up. When does it start warming up in Scotland? Our son and niece are going on a UK vacation in April.
