Wet Cab Floor Insulation Ducato X2/50 2007 (1 Viewer)

Hi

While fitting a Sterling B2B the other day, I noticed that insulation under the cab plastic matting was wet. I noticed this while I had the engine battery cover off - you could see the wetness in the foam. The insulation is for sound-proofing rather than heat retention - its the green speckled stuff.

Anyone got any idea's where this might be coming from? I have a few ideas:

- Condensation running off the inside of the windscreen down the back of the dash and into the floor

- Poor sealing around a wheel arch meaning that driving in wet weather forces water inside

- From the void under the wiper motor?

- From the heater matrix

Van has no air-con so its not condensation coming off the air-con pipes.

Anyone else suffered similar and located the source?

I had a similar problem on an older Ducato many years ago. It was eventually found to be due to a badly fitted windscreen. 'Luckily' the screen cracked and after refitting no problem.

just an idea.....

i had this problem on a car a few years ago.
it was water leaving the windscreen scuttle via the drain tube which went into the wing area.
this was running onto the radio aerial coax where it entered the cabin through the inner wing.

the rubber entry grommet had dislodged and left a 1/2" hole allowing all the water to run down the coax into the footwell.

also worth checking the drain tubes arent blocked and water is filling the scuttle void to a point where there may be a cable entry point or similar into the cab.

I think I found it

Hi

I think I have located the leak, but if I am correct then I am surprised that others have not had similar. Its been very very wet this last couple of weeks here in Scotland, resulting in many road-side ponds. Looks like driving through puddles has forced water up, and through the wheelarch where there are some wee plastic bits sticking down. The plastic bits are used to secure cables and provide a fixing for some interior trim.

I'll test it with a hose, dry it out, seal it up and check that it does not return...
