please can you help, i have a mercedes clk 320 w209 a 2003 model, i seem to have an intermittent starting problem, i can turn the key and the car starts straight up and runs fine but if i switch off and then try to start again the engine will not start. It seems i have to wait a good 10 minutes before i can get the car to start, i have had the cam shaft sensor changed and have no fault lights lit or any faults held in the memory. Has anyone had this fault before can you please help. :lol:
