Hi all,
I have an intermittent starting issue with my '03 CLK320.
About 25% of the time, when I turn the key to start the car, all the "position 2" stuff happens like normal (the steering lock comes off, the dash powers up, the seatbelts come out etc.) but when I turn it to position 3 to start the car, the engine doesn't crank or it cranks for a millisecond - almost imperceptibly. If I hold the key in this position it will often crank totally fine and start a few seconds later, or sometimes won releasing the key it will then crank and start. Even rarer still I have to turn it all the way off and then try again. So far it has always started after one or two goes.
So far, I have charged and 'reconditioned' the battery (which shows healthy readings), changed the battery in the key, changed the starter relay.
From the searches I have done so far, this doesn't look like a common set of symptoms. No warning lights are shown and no codes are stored. The tacho doesn't show any revs when it refuses to crank.
Does anyone have any thoughts on what I should try next, or what the problem may be? Any help appreciated.
