i've had my R for nearly a year and i have had nothing wrong with it so never really had to do a diagnostics in it, but i decided to do one anyway. And to my surprise i get 2 errors, AFM and knock sensor. FUnnily enough the has feels fine, power, driveability, boost, everything is beautiful.
On the manual it says you will get an error not only when the sensor is stuffed, but when the ECU gets a lower or hiegher than usual voltage. What im going to do is re-ground the AFM, hopefully this should clear up the problem and improve my fuel economy (a OZ member got an extra 80kms per tank just grounding his AFM). As for the knock sensor im gonna pull the connector out and clean all metal connections and replace it and make sure its nice and tight.
