I've had my V60CC in to Volvo today to investigate and fix the error messages which have continued. The systems involved were the Turn Indicators; Brake Lights; Wiper Failure; City Safety; Driver Support System; headlights; Sat Nav; locking system; cruise control; speed limit readout. Volvo said it was the DCM module which was failing to communicate with the other systems and that they'd seen the problem previously on other cars. They were a bit vague on what they'd done and said if it starts again they'll need to contact Volvo to replace it as it's a pricey part. Can anyone throw any light on this? I've searched on DCM module without any sensible hits as to what one is in relation to a V60
