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 drive it enough for the engine to warm up to regular temperature.
When I have the issue this happens:
- I turn the key to position 2
- all dashboard lights appear as normal except for the coiled shaped one (diesel prewam light ?), which doesn't appear at all
- the displays shows "Run flat indicator inoperative" message
- after a 4-5 seconds, the engine fan starts running at full power
- when I try to turn the key further, nothing happens, engine doesn't crank

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

 

Its gotta be a fuel system fault. Or do you think your car has plugs!! Get the car properly scanned for faults!!

 

Hi, thanks for replying.

These are all the error codes that I get on the second scan (when the car won't start):

ECM: not showing at all.

Clear all the faults--------then restart------what comes back

 

Was this problem solved? I have a 2004 CLK320 with similar symptoms: no start, C1038 and C1022 errors.

Thanks
