We've had our Pluriel since new (5 years old now) and it's never leaked a drop until now. It'sjust hd its 40,000 mile service by the dealer we bought it from (Yeomans off Torquay) and they have changed the pollen filter for the first time. Could this be what the problem is? Please advise me on how I go back to the garage as I am exteremely fed up about this. Many thanks. Christopher Biggs
