good day, I ask advice on a problem that occurs repeatedly on my 159 170 hp. 30,000 km is turned on the yellow light "check engine" without any reduction in performance. The service imput? the cause of the lambda probe. Replaced this, after 2,000 km of new the same problem and the other replacement of the probe (not the same). another 10,000 km new episode and the service alpha was provided to turn the power off and reset the error. Last week, new ignition.......? the case that intervene radically to eliminate the hassle. I have to say that I alternate?? the city, highway....that I provide to run the engine occasionally runs, high average, etc....certainly, there are episodes that annoy you and make you lose time. I would like a motor pi? ready, then the elimination of the dpf egr and remapping. I live in Abruzzo and, if you would like directions to someone referenced my area (the area of Rome) which is able to intervene. Thanks to those who wanted to answer me.
