I have noticed that the drivers side tailpipe of my 1994 S4 drips water occasionally. Last night there was water vapor coming out of the exhaust after a one mile drive. I checked after a couple of short drives today and there was no vapor, just a few water drops comming from the tailpipe.

The coolant level is steady and at the proper level.

I use 93 octane fuel, the car runs great, no other obvious problems other than the occasional water vapor and water drops coming from the exhaust.

Any suggestions?
