You cannot afford to flood the battery compartment, the windscreen motor is in there and the Engine Management, so take out the battery, and below it is a rubber grommet with a drain tube in it. Take it right out so there is a bloody great hole so it cannot be blocked by leaves and other rubbish. Road dust might get in but that it preferable to a major disaster when water gets past the seals and into the Engine Management Computer system. That WILL spoil your day.
It happened to me, but the seals held on the ECM, but it cost a Wiper Motor and the alarm sounded half drowned for the rest of the summer. Various intermittent ECM faults showed up for the next week or three (i.e. Fault Code 17655 - Stroke Sensor Nozzle Needle - G80) but eventually full power came back. Sometimes disconnecting the battery for a few minutes (or a few hours) will reset spurious faults, particuarily after a nearby lightening strike. = regards = Supersparks +
p.s. Maybe there should be a Service Bulletin to check the battery compartment every time the bonnet/hood is raised and if water is present then remove the grommet. It is not an easy job to lift the battery because various bits of trim have to be moved, but if the battery is changed - then take out the drain grommet. = Would be nice to hear VW comments on this = Supersparks +
