Thanks All
I have asked him for more pictures to be sure of various angles and of the pipework etc. I'll send them across for closer inspection Bex if you don't mind?
On with the search.
I have found another source of them in the UK but am checking where they source their parts from first to be sure.
Failing that I will be emptying the piggy bank and heading to Audi, who even charge a surcharge for using plastic! I just can't win on this one me thinks.
Meanwhile she sits on the drive, waiting patiently! and I get to know the local filling station girl well as I tank up the Jag
Will keep you up to date
Cheers
