Excellent car with no problems until just prior to expiry of 3 year warranty, I found standing water in driver footwell following long round trip Bristol to East Anglia and back. There was one day on which very heavy rain and lots of standing water.

On 3 year serviced they were unable to find cause - I elected to see if it was one off incident rather than put in for 3 day "leak test". Following return from trip to Yorkshire 2 days ago - water ingress to driver footwell as re occured.

Is this a leak in floor - or as someone has suggested possible a leak from air con?

Your comments would be much appreciated. I am booked in with VW garage for water leak test
