Thanks again John. I sent an email to Pendragon (who i believe 'own' Evans Halshaw) on Tuesday night, explaining the issues i was having and that the dealership were refusing to make any repairs.
Although i've not heard anything back from them, i called EH yesterday to explain that i'm working away and couldn't collect the car until Friday afternoon. Very unexpectedly, they came back to me and said that they have another part on order which is due to be delivered and fitted to the car today.. The delay in me collecting the car is not a problem as it'll give them chance to 'run it and make sure everything's ok.. If there's any problems they'll ring me back'. As i was at work i couldnt question this any further, so i'm very curious as to what's now going on. I'm guessing they'll give me some paperwork to show what repairs are been made when i pick it up and wonder if this sudden repair has anything to do with that email i sent?
