Karoq 2020, 4x4, 2l diesel, fsh and c50,000mls, no warranty. Cam belt shredded / frayed recently at 70mph on M4 middle lane, engine stopped effectively seizing as was now mis-timed. I made the hard-shoulder safely. Not a pleasant experience. Skoda Customer Care defending their position with little concern over the incident and possible consequence. They require the car be taken to a Skoda main dealer for analysis and diagnosis before any consideration. They will not consider a 3rd party independent report. Not for me at their main dealer labour prices plus they'd throw the book at the car wanting a total belt and braces renewal of most ancillary components. Frayed / shredded cam belt thought to have snagged causing belt to jump / slip causing mistiming event, what else could it have been ? A complete top end of engine required which I've instructed a local firm to undertake. Financially most painful. Replacing cam belt is no longer a service item beyond changing at 140,000mls. Any advice is battling uphill against the mighty Skoda / VW Group please for what can only be a faulty, defective and not fit for purpose belt ? Thanks Fred
