just had my 230 clk serviced at mb in nottingham and the guy there was telling me that he cannot get my ecu to talk to their computer, apparently hes only ever had the problem once before and that was on a car that had been chipped, im new to the car and i was wondering if there was any way of finding out if it has been chipped or if its possible to remap them at all, mb say that they think they can sort it but it might take time and turn into a bit of a wallet emptier, any help or advice would be appreciated
