C180 Kompressor mystery miss fire

Hi All,
I have a 2003 Mercedes C180 Kompressor. It's done 43,000 miles and is serviced annually by my local independent.
Last autumn it developed a miss fire and put on the orange engine warning light. By the following day, the light had gone off and the miss fire had disappeared.
Then a couple of days ago, it did exactly the same thing, with the problem and the warning light disappearing the same evening.
I've just taken the car to my local garage today and they can find nothing wrong with it. We're just about to head off to France for a couple of weeks and will probably do a couple of thousand miles, so I thought I'd put a post in here to see if anyone had had a similar problem or could give me any advice.
Thanks in advance.
Paul

Hi Paul,
It sounds like you bescribes my car! Exactly the same behavour. I had mine into service to read the ECU. It says somelike low voltage at air-mass sensor, ignition coil error on cyl 2., ECU fault.
Without doing anything more, I had them reset the ECU fault.
Next day, the orange light came on, and this time it was the same errors on cyl 1!!
I replaced the coil on cyl. 1. But it still miss fired now and then. Now the orange lamp has gone off for a week, and the engine looks good so far, but I don't thrust it to stay like this.
Did you sort out your car problem? and what was it?
