Another update for anyone interested sorry for all these posts but if it happens to you it might be worth the info
I have spent most of this afternoon trying to source the part for less. I have lodged requests with a number of breakers to see if there is the right part lying around somewhere. So far nowt!
I even contacted a chap on EBay who had also bought his from the German chap and left bad feedback his pumps was for an A8. He said the part wasn't OEM as described and he had returned it he suggested A8parts or a breakers
Tried all of them now!
However I found a site based in Ireland that links dealers part stocks and liss them with contacts.
I found an Audi dealer within the UK with the part who has offered to ship it to me for 960. Main agent so comes with the 2 year warranty etc etc
Best offer so far !
Watch this space as my credit card may take a hammering shortly!
Cheers
Glyn
ps Bex are you still on for the fitting guide ??
