Had a typical rear leaky drivers side footwell. Plugged a leaky pipe from the sunroof drain which was front left, bu that leaked into the dash. Dried carpet and underkay out. A month later its wets again. Not around the edges of the footwell, slapbang in the middle? Couod this be a whole?? Didnt feel one. Heard about a vent which sputters into this footwell, just wondered how you check this to be the culprit too Cheers people
