Hello all, Would really appreciate some advice. We have a 09 Grand Voyager which developed a fault (engine light and fault code), after it went for MOT in July. We took it to the dealers who said it was gearbox fault and would cost in excess of £5,000. The advised we took it to a gearbox specialist which we did. They said it was not gearbox, but oil pressure sensor switch. We have replaced it at a cost of £500. Unfortunately the light has come on again! At a bit of a loss as to what to do next. Has anyone any experience with similar Thanks Ray
