CLK 220 CDI 2009
Hi all,

I have CLK 220 CDI 2009 that doesn't want to start when it's warm outside, about 15 C degrees or when I drove it enough for the engine to warm up to regular temperature.
All dashboard lights appear as normal, except for the engine management light which doesn't appear at all and the displays says "Run flat indicator inoperative".
If the engine cools down and it's less than 14-15 C degrees outside, the car starts normally.

I scanned the error codes with an iCarsoft MB v2.0 with the engine on, just after I started it and again when it doesn't start (with the key on).
I used the auto scan feature.

On the second scan the scanner is not seeing the ECM module anymore.

I did the following:
- start the car
- auto scan, scanner shows 17 modules
- record all error codes, except for the ECM, TCM and ESM. I delete the errors for these before recording them, like an idiot.
- delete all error codes
- driver the car for 20 min to warm engine
- stop car
- try to start car, it does want to start with symptoms describe above
- auto scan with key on, scanner shows 16 modules (ECM missing)
- record all error codes

Do you think there is anything that an amateur like me can try to determine the cause of this or fix it ?

And does anyone know a Mercedes specialist around north east London that works in this period ?

Thanks

Sorry, I got the dashboard light name wrong, it's not the engine management light, but the coil shaped (attached picture) one that is not turning on when i turn the key and the car won't start.

You have the same car as me and I'll be interested in hearing how this gets resolved in case it ever happens to me. I know the petrol models can be prone to cutting out / difficult to start when hot and that's caused by the crankshaft position sensor. I'm unsure whether that also applies to diesel models. Good luck with this.
