So, I took on Project GT TDi, a Mark 5 Golf which has it's very own river in the front. Some say that ducks can be found bathing in the foot wells of the car, all we know is that if it doesn't leak then it's not a VW.
It comes as no surprise as 100% of VW's I've owned have all leaked, some in similar ways.
So, this Golf is a 5 door, no sunroof. The water appears to originate up behind the dash. The foam sound deadening behind the dash is soaking and dripping wet on both sides. Apart from taking the dashboard out, I've not worked out how to remove the deadening under the dash to dry it out.
I've removed the scuttle panel to see how water can get behind the dash, the usual suspects, bonnet release grommet, access panel and on the passenger side the cabin air inlet vent. Under the scuttle panel it doesn't appear wet around these areas, though the pollen filter housing is where my MK4 was wet on the passenger side.
Photo, shows the drivers footwell, it's soaking far left and far right. Far right, bonnet release leak? Far left, water coming into the air ducting perhaps from the blower air inlet?
The white stuff is talc which helped me trace the flow of water.
So, have any MK5 owners here had a similar leak with similar lines of diagnosis and fix?
