I bought a brand new diesel Volkswagen Golf in January. There was a series of minor problems at first; tyres at the wrong pressure, pulling left, a burning smell next to the front passenger wheel arch, the motion sensor switch hanging out the wall and it using a lot of fuel. The thing that scared me most is the engine, while slowing down, cuts out and restarts itself. The garage can't find a fault and aren't happy that I've rejected the car. I have driven Golf models for a very long time and they've all driven well except this one.
