We always assume main dealers keep everything above board.I know different,things are pretty tight for all of them at the moment.I wouldn’t trust a main dealer any more than the guy that buys out of farm sales to sell on.Especially regarding engine emission equipment .Aircon has to be part of the warranty for me end of story.My dealer replaced faulty spool couplers under warranty and another local dealer wouldn’t,sounds like they make things up to suit,one things for sure my dealer was excellent.
