Hi all Wonder if anyone can help? When locking my 2002 C220 CDI using the key fob the indicators flash 3 times as normal and then proceed to flash quickly until turned off, if I repeat the process 2 or 3 times it will eventually set and be fine, occasionally I come back to it and the indicators are flashing, no alarm noise though! I have checked all doors etc and they are all shut properly. HELP!!!
