Another electrical blip....maybe
The Spider has developed another little fault, three times now Ive had it but it resets.
First two, for no apparent reason its gone into limp mode with he usual warnings of VDC, ASR and Hill holder not available and 'get engine checked'
The first time was a day before its service two months ago, Laurence at Autolusso deleted the warnings and its was fine but a week ago it happened again, I tried the usual battery reboot several times but no good so I phoned Autolusso, Laurence said to try an overnight battery disconnect but instead I plugged in a MaxiScan OBD 2 reader, it came up with Throttle/pedal position sensor switch B circuit.
I reset the fault codes and it was back to normal, no apparent problem until yesterday when I hit a big pot hole quite hard and it knocked everything out again, same as above, limp mode, ASR,VDC etc
I plugged the reader I and cleared the warnings and everything is fine again.
Anyone have any ideas, could be that somethings loose, could be an actual problem with the sensor but it seems strange that it clears the problem simply by clearing the warning.
