Solution for famous P0010, P0011
I want to share my experience of a half-year struggle with the AR official dealership and other "specialists" who told me from the very beginning to change my timing chain. My argument that these codes had been intermittent were neither answered nor addressed. I checked with guys from Vauxhall possesing GM1.8 chain engines and they were shocked that so many Alfas change timing chain before 100 K. So, after all I found out that the exhaust solenoid itself was faulty. I ordered it from U.S. ebay GM 12655421 (intake solenoid available as well) for $50, delivery inclusive, whereas in Italy it costs 100 euro. All errors are gone for now. I'm not saying our timing chain is good (although I understand there is a special P0016 code for that), just be sure to change solenoids first.
