not sure about the mode change, but twice, maybe 3 times in 4 years, my X SST has done something similar, let off the accelerator (say as you go round a tight corner), press the accelerator and nothing, but every time, press again it works. Only a guess here, but i think it maybe related to the fly by wire accelerator pedal sensorNo increase in revs, the drive just fails, I have noticed it's gone to manual mode when I havnt touched the paddle shift.
I'd start by checking for stored fault codes, engine and gearbox, could easily be something simpleThanks Stu, a couple people have said solenoid problem which means refurbishing the gearbox, which moneywise doesn't make sense. So if I can't cure it easily I'll sell it. A sad day after 11 years awesome driving !!
Thats handy, so if faults have been cleared previously recently, the faults shown now should be relevant, definitely make a note of all codes stored now. Maybe worth saving them for someone with MUT tool (Mitsi or specialist :mitsi to make sure you get all codes. Chances are that will point you in the right directionThe first it stopped it was checked over by the AA who found a load of random faults, so cleared them and it was fine for 1000 miles !! But will get it cleared again, thanks anyway
Had diagnostics done and showed no faults apart from rear speed sensor ( ABS ) which I knew about and that's all !
How annoyingShould have mentioned it was a full diagnostics check
