Bought a 2018 Golf in October. Had a few small issues, knocking from suspension and brakes.  Took my car in under the VW 2 year approved warranty and CRA 2015 for it to be repaired. Not fixed, car came back damaged. Mechanic drove it like he stole it with me on a test drive. Denied all damage until I showed a video I took when I got to the dealership 15 min prior. 
It since went back again, got more damage and told it was test driven and it’s a normal noise(metallic clunk from suspension). 
They’ve now said they won’t look again, the warranty isn’t worth the paper it’s printed on. VW are useless as support and this dealership is even worse, lies, lack of communication(even to VW Support) and a complete Joke. 
If there’s one thing I can say, DO NOT BUY A CAR FROM THEM - AVOID AT ALL COSTS.
