Hi Suzie
I am not too far from you and I always use Paul from Crossroads Garage in Ludgvan (01736740880). He is a really nice chap & a great 'can do' mechanic. He has looked after my Alphard and several Bongos before my Alphard. He seems to be able to sorts issues without full main Dealer diagnostics. His only gripe is that he reckons Japanese engine mechanics have very small hands!...as access is very restricted. Worth a call. Chris 😀
