I bought a 61plate vauxhall astra in feb2012. It was nearly new and only registered in dec2011 with only 30 miles on the clock. I have been having problems with the ABS light and traction contol lights coming on also the engine diagnostic light is on. I have taken it back to the dealership where it was bought from and they said it was a faulty sensor. I have taken it back today to be repaired and they are still having problems and can't understand why the lights are still on. Obviously I have concerns that they will tell me there is nothing else they can do. Anybody now what my rights are?
