Just to update you...
Took it back to the dealer who said he'd hae a word with the service department to organise getting it fixed... No hassle, no excuses, just a "no problem, sir" attitude...
If all goes well getting it fixed, I reckon they'll deserve a listing in the Good Dealers post!
Thanks for all your speedy help and advise! E-beers all round!
Cheers,
Doug
