The extending aerial on my A4 2.8 cabriolet (R reg) has broken and needs replacing. The nylon drive strip which runs inside the aerial is toothed. Audi no longer supply this so it is neccessary to get a complete replacement.

A new one is some £166.00 - no thanks. So it is a matter of looking for a second hand one, or something similar. For example there is an item on eBay (http://cgi.ebay.co.uk/ws/eBayISAPI.d...:X:RTQ:GB:1123) but will this be suitable. Alternatively can anyone please suggest where I might buy a replacement unit at a reasonable price.

Thanks in advance for any help.
