Hello! I had to change the engine of his Omega Caravan for a friend. (X20XEV, Bj 10/95). After the complete installation the engine ran, but the MKL lit up and the engine ran in the emergency program. Now I have read out the error memory, there was the KWS as a cause in it. I changed it for a new part and also the exchange for the part of the old motor did not bring any improvement. Since in the error memory there was no speed signal I have safe First for the old part, then for a new original from Siemens. Now I wanted to start, the starter also turns busy, but it doesn’t seem to ignite at all. It can hardly be that the new part is now also defective. Do you have to learn the new NWS? What else could be the reason that the engine only runs in the emergency program? Must write that I had to change the harness from the KWS to install the KWS from the old engine. The plugs did not fit. together. Ignition module, idle control, throttle valve unit, AGR, NWS and KWS have been exchanged… What’s left? Am really desperate… Many greetings from Steini
