VW breakdown cover is only free for the first year and nothing to do with manufacturer warranty.
VW used to do what they called the "mobility guarantee" if you got your car serviced within the VW dealership, up to 5 years old (the length of the standard or extended warranty). It was never really sold as a perk to dealership servicing but it used to be anonymously placed towards the last few pages of the brochure for your VW car.
You didn't get cover for putting diesel in your TSI or having a flat tyre, but if your car broke down through parts failure/leakage, they'd come and get it FOC and take it to the dealership to be fixed under warranty.
They might still do it, but just not shout about it.
