We have a 2007 MINI Cooper S convertible. At its recent MoT we were told the car has failed as both the headlight washers are not working. The probable reason given for the fault was "driving on bumpy roads" or being hit in a car park. There are no marks to indicate the latter - and why both washers anyway? Apparently there is no evidence of a car design fault. We have had the car since new, now 38,000 miles, and only one washer has been operating most of the time. We did have that replaced two years or so ago at a cost of £498. We accepted that as "just one of these things". But two questions: Why is the inoperative headlight washer a "fail" when many cars do not have them in the first place? And are MINIs not supposed to drive over bumps? Is there an alternative to the £1000 bill to be paid to enable our car to pass its MoT?
