I wish I'd read this two days ago! Just paid ?70 for the regulator and my mate ?30 for investigating then fitting it (better than main dealer, they wanted ?140 fitted).
I shall be calling the dealer ask a 'new' customer to ask about the metal clips though.
And I certainly wont be paying them ?256 for a 60,000 mile service, even tho its overdue. This might amuse you......I asked what they did for ?256 and was told that they changed the oil, and checked all the lights, etc..........my immediate reponse was: "f**kin ell for ?250 I can check the lights myself"
