got a vivaro high top,spent a bit on it lately,having problems with the red service light which debilitates the engine when it comes on,i switch engine off whilst im going along,although the light comes on again it then runs ok.
my mechanic has tried everything with the ecu unit which tells you whats wrong
we are now sending this unit away to be tested if at fault they can be fixed or replaced at a large price
anyone had similar problem?the renault traffic,nissan primastar are all the same van
basically french made by renault
