hello Errecinque thank you so much for the support, I tried, in diagnosis does not appear the error, but is the MIL on, without giving me any error in diagnosis

Then with winols display, 16-bit hex Search for the value 0403. You'll see that just before the first Bit cleared to me there is another one that refers to the lamp light. Now, unfortunately, I do not have the pc, try you should still be able

hello R5, unfortunately, I followed your advice and I cleared all the 0403 hex, but nothing to do, thanks again for the support and best wishes for a merry christmas

sure here it is p.s. I have copied your advice on the file that I have in the ecu now

You should try file ori only with the bits 0403 reset (at the bottom of report it ori nothing to do with the area of dtc), because, according to me, the light will turn on for other reasons related to the mod, you have touched some strange things

ok tonight when I come back from work, I feel, because if I try to just connect the actuator to the egr I will turn off the light so I think it is inherent in the valve itself, possibly put a resistor of the same ohmic value so I should resolve
p.s. what are the strange things? in such a way so that I solve it once and for all

Hello Errecinque I did the test and the result is not changed, light is turned on and the diagnosis no dtc

Solved by inserting extra resistance that are found in lamps to the canbus connector on the egr
thank you all for the support

Good and simple solution is good, the value of resistance?

From the digital tester gives me about 60 ohms
