Angry Engine warning light on and triangle light on ...
Hi everyone, I have a problem for two months to this part: engine warning light on and triangle light on. The engine does not match the 3000 rpm, I did manual regeneration of the DPF with both OBD2, on the road but nothing. I've replaced the lambda probe, the gas pressure sensor, the common rail fuel pressure regulator and the rail fuel pressure sensor, I checked the intercooler sleeves and are full and swell normally in acceleration. The lights continue to stay lit even by resetting them with OBD2.
What else could be? Has any of you ever experienced such a thing?
Help me, please ... I'm crazy !!!
Meanwhile, thank you in advance for any answers!
Regards to everyone from Italy

I answer myself: I had to replace the ECU. Now everything is OK!

On ebay there are used to 500/600/700 USD, the important thing is that with the same original code, you make a clone from mechatronic for about 250 USD and finally reinstall on your Star.

Thanks, but I have already solved! I have already replaced and cloned the old control unit. The problem was that a driver was short-circuited, just the one that managed the Y74 valve regulation.

Glad to hear it is fixed. A working car is the most important, and the most fun to enjoy. :
