Hi Everyone! When ever I park my car I notice that there is a slow leak coming from the passenger side just under the bumper area. Its a clear oily drip running down the side of the radiator, hits the inside of the bumper then the ground.. Attached is a picture of where i noticed the fluid to be building up from It starts below the bolt in the picture. Still not really sure where its coming from.

I also looked at the PCV hoses and noticed some wetness in that area as well, not sure if its the fluid being blown back to the front of the motor. I stuck a piece of paper under the leak, and it look like a mixture of water and some oil/dirt. It drips as soon as i am parked but only lasts for a few minutes. Leaves a wet area on the ground (about 3 inches in diameter).

Any Ideas?

 

Most radiators on Audi's with an automatic transmission double as a transmission fluid cooler. Could be leaking for the transmission portion of the radiator.
