My A4 has the SE alloys like in this picture:

I need replacement centre caps but the genuine parts are very expensive. Where can I buy decent replicas?

I have searched eBay but there are many different varieties and the listings I have looked at all require you to check yourself.

Is it simply a case of making sure the diameter is correct?

I am in UK.
