Hi Carl
Speaking as one of the unlucky ones who had the fault, went to Audi who diagnosed a new sensor was needed but didn’t have one in stock, then was allowed to drive away with a return booked for 2 weeks hence. 4 days and 19 miles later the ABS ‘bricked’ borrowing a term being used on this forum 😂 I had my car relayed to Audi then had a huge bill, £3600, to get my car back.
My heartfelt advice, contact Audi Assist who have been known to carry these sensors on their AA vans 🙄 and do whatever is needed to have them come out to you. If the dealer says they will cover costs then the small cost of joining Audi Assist £99) should be a bonus to you going forward.
Good Luck Pen
