Couldn't see any bungs. Removed nearest bungs to the a-pillar area under the car and no water came out.

The bungs are under the battery in the plenum chamber, also replace the cabin filter housing seal, search on this site for instructions on how to do!

Oh yes I have done all of that. Fixed the cabin filter seal etc. If u look at the photo i posted the water is accumulating in the skin of the chasis and bleeding through near the floor. This seems to be different ingress point to the typical cabin filter seal. I don't have a sunroof either (which potentially could have been the cause).

Don't know if applicable but the inner doors brose metal panel seals perish in the lower half .

They all need resealing regardless .

Don't have my car with me to check, but is there a blanking plug on the passenger side of the car that corresponds with the bonnet release cable grommet on the driver's side? I say that because I cured a very similar looking leak on the driver's side of mine by replacing that grommet.

Hi, sorry to resurrect an old thread, but here is my problem.
I found water pooling under driver side front and back.
I always kept plenum chamber extremely clean and got rod of grommets years ago.
When i flush water on the windscreen it goes down the hole under servo and battery without obstruction.
I replaced the ecu seal and sealed bonnet release cable.
Got to say, found a lot of rubbish behind ecu case which was not visible.
I dried the car thoroughly.
Now, whilst replacing front driver seat, i lifted the carpet and found it a bit damp.
Passenger side is bone dry.
Tested all other water ingress points and all is good.
Could it be the cabin filter seal which i haven't fixed yet, even though is on the driver side only?
Thanks

Checked the door seals?

**Jimmy2007** · 11-03-2020,03:52 PM

Yes, hosed the doors for 15 minutes and the little water that goes in the door from the glass seal, goes out from the bottom.
Carpet was dry on door sides even when i found gallons of water, so i don't think there's a problem with the doors.
Or should i test them in another way?
Thanks

Try parking with the driver's side up on the pavement, then hose the doors again. This has made door leaks more obvious in my experience. Feel for any moisture just under the bottom of the door cards.
