we were offered this when we bought the wife's A3.. sounds good but there are only so many times you can claim and as with any insurance you have to tick all the boxes before you can claim and it wasn't that cheap.If if you were to have four damaged wheels then this would be classed as four individual claims.as I can remember each tyre was covered If they were slashed or the Tyre fell apart no if Audi could and would prove it was the tracking...too many if's involved ,think it was about £450 ?? over 3 or 5 years.
hope this helps,
