2 questions. I have a magical coolant leak, what are the common spots for coolant leaks on these car
 

cars? My doesn't have the belly pan, but I doubt that effects it too much. The other question is obvious but I am just checking, I have a wire in the trunk by the cd player w/ a coax lookin connector. GPS pre-wire?

Any elaboration?

Right here.

Oh, boy....
 

Maybe I'll deal with it when it gets warmer. The leak is towards the front of the car, tad off to the right. I gonna go under there, check the lower hoses. The top passenger radiator hose was replaced a week ago.

or water pump-mine had a dribble so it went to the doc-slow leak

Sounds like X marks the spot.

High point vent o-rings and resevoir cap
 

The guy who bought my car has had it almost four months and no low coolant warning light.....funny. I use to get it once every six weeks or so.

I had been looking for that leak for a long time, and I cranked down on the resevoir cap before selling it....I think the gasket was worn.

If you get under your car and look up at the driver's side of the engine with a flash light, you might see some pink stuff there also....way up at the top. I've seen that on a face lift car also.<ul><li><a href="http://www.audipages.com/Tech_Articles/enginemechanical/coolantexpansiontankreplacement.htm">Pictures of high point vents here</a></li></ul>

oilcooleroilcooleroilcooler - that's a dead ringer for it

I have no oil leak though, and it hasn't been doing it until recently.
 

After audi did some front end body work. I might try to get it out of them, if not I'll just top it off untill it gets warmer and then I'll do it and will probably have questions here.
