I just noticed I have lost 2 plastic caps on the Wheel nuts. Does anyone knows the exact code number for them or where I can pick up a cheap ones as they seem to be very popular on eBay . They are grey and I think 17mm.
17mm is what you need. As you say, plenty on eBay. Pictures often used on sites like eBay often show genuine Audi ones, but the ones you will receive are usually from China, so read the description carefully.
Some of the Audi dealers are on eBay get them from them preferably.
You can get a set of five ( four std and one locking) Or 20
I lost 6 in a week .
Replaced the lot with a different colour look better and fit better.
