then.... on my car... (alfa 147 1.9 mjet 150 hp), although the series does not have the dpf, if I touch this bit to disable the lambda that was present in the exhaust.... right?? I say so because? no cel, I put.... the framework does not mark anything, but now diagnosis I find the erorre of the lambda disconnected!! do I have to do the test.....
for the moment I'm interested in off the light on the painting of the 159..... no one knows with certainty how can I do???
