Hi,
Mate, driving home last night, 60 mph, all of a sudden he loses engine power, no response from the throttle.
Manages to coast to a safe place to pull over and the engine is still ticking over ok and still not responding to the throttle.
He turned it off and tried to re-start and whilst it turned over, wouldn't fire up. Got it towed to his mates garage (not sure if he 'knows' VW's) who has put some sort of OBD reader on it and it's showing a faulty knock sensor?
What are the chances that is the fault and if so, any idea how easy it might be to change please? eg, Is there failure mode for a knock sensor that is likely to affect the engine like this? If he could disconnect it, would / should that allow the engine to run?
It looks like it's up the back of the block and access might be difficult? ;-(
He's going to try to put a better code reader on it himself in the morning to see if it's showing anything else of if they re-appear when cleared etc, but in the meantime, I said I'd run it past the good folk here for him to see if anyone has experience of such?
Cheers, T i m
