I had a new Volkswagen Golf delivered on 11 April with 120 miles on it. Four hours later with 200 miles on it, the car went into limp mode. It was taken to a Volkswagen main dealer and I was supplied with a hire car. Two weeks later, the ECU and injectors have been replaced but they still don't know what the fault was. They've now replaced the cylinder head and said that has fixed the car, but I have no trust left in this car and rejected it. They have now come back to me saying they would like me to take the car back and will offer goodwill, although didn't give any idea of the goodwill offered. It's on finance and the finance are fully aware of the position. I'm worried that the car will be faulty again soon and then out of the 30 rejection period. Should I keep the car or reject it?
