1997 VW Passat - water in cabin - Wee Willie Winkie
Afternoon all,

Long time no see! I?ve been away for a while, but now I?m back!

My 1997 Passat has a water leakage problem. Whenever it rains heavily, water finds its way into the cabin from behind (as far as I can tell) the glovebox. This causes no end of issues as the heater blower motor is situated there, which I?d already had to replace once.

I few months ago I did have a prod and poke around the drainage hole, which I believe is around the area of the pollen filter, but the problem persists.

Please could someone tell me the exact location and procedure to check if my drainage hole is blocked?

Many thanks in advance.

DB

Hi DieselBoy, how's the bug doing?

There is a cover over the polen filter that is oftern not replaced correctly because the battery is in the way, oftern it is just sort of placed in position rater that properly clipped into place. To check this undo the 8mm bolt in the top of it, if it lifts away easily then it is not fitted correctly, whilst the cover is off have a look at the drainholes down in the plenumn chamber and clear out as required.
Putting the cover back on should be a bit of a faff as the lip that goes around the battery gets in the way of sliding the cover into it's guide on the under side of the scuttle panel.
This probably makes no sense reading it here, but should do when looking at the car.

Cheers

Howdo!

Getting quite a collection now! Sold the Baja and bought a 1303, then a 1970 1500 and the girlfriend is about to get a fully restored 1970 1300!

Thanks for the tips. I'll have a stab on Saturday when it's actually light (winter nights are drawing in)!

Cheers.

Hi. just tightening the pollen filter housing won't work, If you remove the pollen filter then the three 10mm nuts holding the pollen filter housing remove the housing and you will see a foam gasket and a kind of foam/gasket type seal in a resessed appature in the pollen filter housing, this gasket splits and this is what leaks! you need to remove this gasket and replace it with a thick bead of sealant, If you go to your VW dealer they have this sealant on a roll and normally sell it for about £5 a metre this is what you replace the seal with. Make sure the join of the sealant is towards the windscreen side of the pollen filter housing e.g. the higher side of the housing. Clean the surface the pollen filter sits on then refit the housing!! and hey presto should be the end of the leak!!
