I hope this is how I reply to you. The letter is very helpful but the faults have all been different, apart from air suspension, which they said was fixed with a software update but was not. This had to be replaced.
The car was bought on 21st June so I'm beyond 6 months, just. Still worth pressing to reject I think. The dealer would be happy for me to drive it until the fault code is back. As a lone female I am certainly not going to drive it and get stranded.
