Yes, thank you Wigwam. She didn’t mention that about diesel either. I remember now that my previous car before the one I have now (Mini Countryman 2.0 SD) had problems and the garage said it was due to a build up of carbon (I think?)
If I change to the petrol model and I can get 35 mpg or above, I will be happy with that. Did you have the sdrive petrol or the xdrive petrol?
