Great thanks to nemiro and viper-666 helps.
Done :
* Immo of the SLK works :


* Seems the ECU don't have the information when I'm pressing clutch pedal. Keep inactive, whatever I press the pedal :

* Control Clutch pedal sensor + wiring to ECU :

Pin 4 of the ECU to the mass. Open when we press the pedal = OK
* Viper-666 give me EEprom file from an Mecanich gear box (with my key): no change. Setting must be saved in the Flash or other ... Many thanks to him
* Nemiro confirm my last problem could only come from gear setting. Thanks to him
As I don't have MB Star, i decide to confirm to try to start with pulse relay :
I push the relay of the pulse modul.
It's start. As Nemiro said, I need to configure my gear setting to solve No start.
In the same time, acceleration was not good. Few minutes ago, go down, and I've got a Throttle error (P202E = P0120 ?).
I will have a look on the Throttle end of this week... the car don't turn since 1 year and a half ..

Lot of works on this car ... but good news, I learn lot of things on this car.

Thanks to all

Nicolas
