So got a call today, the dealer has re-checked all the logs, done compression testing and "could find nothing wrong" :freak3: they test drove it twice but on the second outing detected a hesitance at 4500 rpm. Following a discussion with Subaru the ECU was reset. On the subsequent test drive the mechanic reported improved response.
So after frightening the living daylights out of me with suspect ringland failure I now have the car back relatively unscathed, if I ignore the scratched duracon gear knob and center console it took me an hour to polish out the knob scratches... you can just imagine the comments from my other half never realised how hard it was
Anyway I'm told I have got an un identified fault, the ECU memory has been cleared an I've been asked to go back as soon as I experience any hesitance so they can check the logs. I have also been told to keep a close eye on the oil level, but I check that every week without fail so that's not a problem.
