Hi Richard I 'discovered' this is France when an over eager petrol attendant washed the back on my +8 with petrol he overfilled it so much and then much arm twirling and throwing buckets of water over the paintwork. All was fine until the next day and about 3 miles in to a day out the thing just cut and reverted to tickover, ticked over a treat until I tried to drive then cleared and did it all over again. I could smell fuel and started to look and found the EVAP pipes full of fuel, a massive struggle got the carbon canister off the car (tucked up alongside the fuel tank) and I poured half a pint of fuel out then let the thing dry in the sun, after that I left the car ticking over for half an hour to dry the pipes.
I actually managed to do it again, my fault, when over filling on a long run back to the ferry....never did it again after that! Glad it was a simple one ;-).
