Hello all. My first time on this forum, and I could do with some help please. It's a P38 2.5 DT Auto that I got a couple of months ago.
There's some sort of fluid coming from the floor level vent on driver's side on the transmission tunnel. It's odourless and colourless and I can't see any levels decreasing in the various reservoirs under the bonnet. There's not much, and I can stuff a bit of kitchen roll in to mop it up every week. Looks like it's been doing it for a long time as the carpet was full of it when I got it. Got that dried out now, but where's it coming from?

+1 to O Rings....

These little bastids seal the incoming pipes from the engine bay into the Heater Matrix manifold. Over time they go brittle and leak. They are located on the drivers side of the heater box which is why the tell-tale is wet carpets on the drivers side transmission tunnel and footwell.

Now heres the kick in the pants....they can be a total sod to replace!!

Plenty of shortcuts to get to them, but is not a job for the faint of heart it can get very frustrating!

Good luck!

Er, if its odourless and colourless as stated, is that not water? Especially if coolant level is not dropping. If rainwater, I'll post you some pics of where it is likely to be leaking later, too knackered to find them at 2am.

I did see a post that said that if it tasted sweet then its coolant. Don't know how true that is?

The screw that's in the picture just off centre was the cause of my rainwater leakage into the footwell. It can do it either side. It can really pour in here, bypassing the pollen filter cover, straight down the filter duct. Needs over sealing with silicone as a quick fix.

It sounds to me like the the air-con drains are blocked. If you get underneath and have a look above the gearbox, there are two drain pipes coming through the transmission tunnel, they are black rubber and have a crossed opening (you will know what that means when you see them) push a screwdriver in to open the 4 flaps, if lots of water comes out, you have found the issue. Once drained, clean the inside of the pipes, I wrapped some rag round a screwdriver and wiped them clean, do both sides. I check them every time I have a need to get under the car.

+1 on the air con drains. I had to blow mine through with an air line. ****ed loads of water out after that. Now just a gentle trickle

Yep - Bitter sweet is coolant
Soapy is washer fluid
Slimey and slightly burnt tasting is Engine Oil
Slimey and a hint of fishy is L322 ZF Gearbox Oil
Slimey and Red coloured is Autobox or Powersteering fluid
Bitter and sharp is Battery Acid!

Thanks for all your replies! Looks like I've a bit more research to do... It's not rainwater coming in for sure. And I haven't used the aircon so not the drain either. Don't really fancy doing the taste test for anti-freeze but it might come to that... It doesn't evapourate like plain water - is this a sign?
Thanks again, I'll let you know when I find out for sure.

Yuck! Yup, it's anti-freeze alright. So thanks again to Saint.V8 and everlatesparky for hitting the nail on the head right away. Now to see about those O rings ...
Saint - you ever done any wine tasting?!
