Anybody knows where the AC water exits on the R-Class (maybe the same on ML and GL?)?

Thanks!
 
If you are referring to the air conditioning fluid, it should be removed and stored in a tank, it is supposed to be bad for the environment and carcenogenic, bad spelling :D The drain plugs are usually under the bonnet and have plastic caps on them, usually black and mounted on the metal parts of the air con pipes.

I think he means the (inert) water produced as condensation by the aircon - it usually forms as a puddle under the car when parked, leading passers-by to rush up to draw your attention to the huge 'leak' you've (not actually) got!

I don't know the answer unfortunately! :dk:

I was concerned that I wasn't seeing a puddle under my w221 S-class. When I looked for the pipe, thinking it was blocked, I couldn't find it. I had it pointed out to me by the merc specialist when up on the ramp. You have to take off the undertrays to find it, directly below the evaporator. It drips into a pool in the undertray and evaporates from there. Hence no messy puddle. I assume the R class will be the same....

That makes sense - the amount of heat under the bonnet of my R500 would boil a gallon off in the blink of an eye! :eek:

Yes, that is what I'm looking for - the water produced by the AC system and which drips off underneath the car, I need to know the where the drainage pipe resides and the water exits from the car.

Thanks again!

That answers something I've noticed on mine too, never saw any water puddle under mine either.

Bump the bump...

Bumper...no one knows this? Possibly the same on X164 (GL) and W164 (ML).
