Today I discovered another problem. The manual steering wheel buttons for the gearchange don't work consistently. This morning they wouldn't work at all. They were OK on the way home. Then when I went out again I could change up to M3 while stationary, which is correct, but I couldn't change down with the other button.
If I leave it in D and drive the car, it's fine and when I choose M it moves OK and the correct gear shows, but when the buttons don't work, I can't change it, but it will drop down the gears as I slow and select M1 at rest. Then driving off, it stays in M1 and I can't change it - sometimes.
All the other steering wheel stuff works. Well the dashboard SID stuff. The radio buttons are not connected to the replacement head unit.
