Recently bought my 3rd Abarth, my first 595 Comp. great fun but I seem to keep getting the check engine light a few miles after I start each morning. The error code is P209716, something about the fuel trim being too rich in bank 1. Spoke to 2 mechanics and have been advised not to use supermarket fuel, to use 98ron and see how it goes. Does anyone else have any experience of the check engine light coming on when using standard fuel? I’m able to reset with a code reader, so it’s not a huge issue but would just like some more piece of mind.
Thanks in advance.
