I just spoke to my local dealer (Bristol Street,Nottingham) and they said they had never heard of or been asked to do this before. They called another branch (Leicester) and they told them the same thing "What are you talking about?". Is this an education problem with Midlands dealerships or is there some secret way to ask that will get the right answer? Can someone who has successfully had there C3 updated please tell me where they had it done and what they asked for to make the dealer understand them? Many thanks...
