Hi. My five year old 1.2 VW polo, 50K approx fully serviced by VW has suffered a serious problem resulting in the timing position moving. I have been told a new engine is required and no guarantee other parts are not damaged. VW is not interested as car is out of warranty even though they have looked after the car since i purchased it new. Unbelievably this damaged happened when the car was stationary/at start up. How can I take this forward as VW are blocking and saying I need to speak with the retailer. Thanks.
