I had my 2 near side Doors fixed last week..(Handles sticking open) It was in for a new Heat shield and i happened to mention it.They fixed there and then 20mins max..No big deal..! .. Our on board Comp always warned us if any door was open so we never drove until it was put back in, Yes a little inconvenient..but no big whoop..!!! .. You have to rememer its a relatively new Model..Things always get sorted in the end. So far i have been back to the Dealer 6 times for niggles, Every little correction and Modification to my C4 makes me feel like i have a Bloody good bit of kit around me..... :) ..
