Thanks for Everyone who’s posted on this topic, Same issue apart from my car is used every day. I ended up buying one from an Audi dealer £100. As I had a week of long journeys, poss could have risked it and waiting for the e-bay delivery but I’ll never know. Anyway in my head I’ve still saved £150 fitting it myself instead of thinking of the £80 difference of the same part. I still ordered one from eBay and now I’ve a cheap spare. Thanks again for the advise I can’t imagine there are too many sensors on a modern car you can get to so easily 😊😊👍
