I got an s320 1998. Is it normal to see a small land after a trip from aircondition usage? Its found under the car between the front wheels. The liquit is not water or oil and leaves a small stamp every day on the ground.
Should I worry about it?

If you drive with AC on and stop the Car yes ,it is Normal for a little Paddle of Water to be underneat the Car where you say ( like a Handfull ) ,all Cars do that .
If you Drive with AC off and then it leaks Water then it is not normal ( you can start to be worried and look for another extra Job to pay for the Repairs,lol ) you would have a Leak then somewehere there ,just in Case make sure that the little T Waterpipe behind the Engine is good (upper Engine right behind it, near the Back firewall ),they seam to leak after a while (Years ) if not check't , if it leaks you would also see a small or big Waterpatch near there where you say but the Engine would also Overheat, making white smoke.
Ciao :thumbsup:
Upps ,just Noticed that you mention that it is not Water or Oil ,what is in then ,Bier/Wiskey or Wine .
W140 full of Surprises,yep,it even leaves a Stamp where a W140 has Parked,what Class,lol.

Anyway what colour is the Stamp or Stain ?

With the a/c off there is no paddle of water. I did not worry about it until those stamps appear. I am not sure what is it? it looks like a pee. A cat or a dog may pee under my car...for sure I I'm not used to get drunk in my garage, only when my wife throws me out of the house. Never mind it looks closer to water. Do u know from where is that water coming out during a/c usage? Is there any specificy pipe that the water should leak out?

LoL,Since you say its a Yelowish coloured Stain i can only assume that it is the Freon Gas from the Actual AC , you could have a real leak there ,when you use the AC while driving and stop ,the Water comes out from the Pipe underneat the Car that you can see if you go underneat,the Waterleak would dry off without any Stain onto the floor ,that's just the condensed Water from the AC operation and nothing to worry about but Yeloowish,ooh ooh .
I havn't come across a W140 with what kind off Symphtoms it shows before the AC Evaporator goes off (brakes/fails) ,i hope that this,your Case , is not how it starts .
If i where you i go and take the Car to inspect it at a Air Conditioning Service Garage ,spend 5 Minutes just to be sure ,unless someone here on the Forum knows and has experienced this ,maybe its just a loose Pipe or a cracked one somewhere near the System ,i hope for you .
Ciao :thumbsup:
BTW: I think the Specialist's who work with AC Defects have some sort of a Dy and with special infrared Glasses (not 3D loL ) they can see where it leaks out from .
I think you have a tiny hole in one of the Pipes since you still get cold Air,thats my Guess .

The w140 has "drain tubes" on the sides of the transmission where the water from the AC condensation drains out. If it is clear, it is normal. If it is yellowish or brownish it might just be the dirt or oil on the underbody mixed with the water.

What colour is the coolant in your car? Some coolants are yellowish too, it could be a busted heater hose. (unlikely I would think).

In my Car the AC Freon is off a Yellowish colour but i think that this Freon Gas also comes in a Bluish colour as well but m not to sure ,i saw it in the Refill Machine but it could well have been the Dy .

Ok, I'll take it somewhere for check. I tried myself to see where the water comes from. For sure I can see a little padle of water on the front side under the engine, on the engine plastic cover. I don't know where's the "drain tubes" on the sides of the transmission but shouldn't they drive out via a pipe?
