It is already biting some people, a friends Golf has had a intermittent bad running problem for a couple of months. The garage who looked into had replaced the air flow sensor with no improvement, a new set of coils and plugs and finally a Lambda sensor. He asked me to look at it and it was obvious if you looked at the live data the cam position sensor was getting an intermittent signal. No fault code but when an engine is spinning at 775rpm and the cam is showing 300 to 350 rpm unless the cam chain has snapped it has to be that sensor.
I have told him to tell the garage about there cr4p diagnosis and see if he can claim some money back that he has spent (£450ish ) as the new cam sensor was only £30.
The Garage is a VW specialist supposedly and my guess is that the parts they have replaced are the usual problems.
