Today I noticed some water dripping from under my C5 Aircross, decided to get under and have a look as I’ve always just thought it was the aircon but there are two small pipes that run through the bottom of the car and one is leaking at the nut, I’ve attached a picture. Any ideas what this pipe serves? It’s not fuel or oil, I’m thinking UREA / Adblue….

Correction, I’ve been under, it’s not the pipe that’s leaking but water coming out of the body plastic hole above. Anyone any ideas? Maybe where the aircon is discharged perhaps or water that’s built up in the rain

If it's coming out if the body it's the air con condensate run off. On the C3 Aircross it's under the drivers seat UK.

As said, probably just the A/C evacuating water. If at the rear and it's a diesel, then if you've overfilled the UREA tank with Adblue there is an overflow.

Thanks, yea pretty sure it’s just aircon run off! It confused me as it had been dripping onto the pipe and made it look like the pipe was leaking until I got right under it and saw the water coming from the plastic outlet in the body (bit of a silly place to have it but oh well!)
