Hi
I recently acquired a Fiat Punto Evo 1.3 MJT, with the highest trim level, which i have been looking for for a long time.
One of the hoses going to the differential pressure sensor was faulty when i bought it, casuing it to run in limp mode. I replaced the hose and thought it would all be good. After approximately 200 km it entered limp mode once again due to the dpf exceeding blockage level. Around this time i noticed it used a considerable amount of oil aswell.
I put an OBD 2 scanner on, deleted the fault code and it started regenerating the DPF. I can't seem to understand why it would only start regenerating when it is clogged beyond 100% and i delete the codes.
I am planning to open the engine to see if it salvageable and change the piston rings - would the oil consumption cause the DPF to clog without the ability to regenerate on its own?
Other than this i am experiencing rough idle on startup. I tried changing an injector, which had fault code tied to it, but it changed noting about the idle. The EGR-valve seems to be in good shape and pretty new. I am thinking the rough idle might be connected to poor compression.
What are your thoughts?
Kind regards Sune
