[ba] Mystery fluid leakage -- '04 A4 1.8T

[Brian Devlin]

Coolant feels oily sometimes- have you tried to mix it with water? I usually 
just get a bit of any mystery fluid on my finger and then drip some water on it. 
Oil repels water 100%, coolant mixes, DOT 3&4 brake fluid mixes slowly. 
I don't think any other fluids are pink on that car - maybe the gear oil, if 
it's synthetic (a lot of Redline oils are pink).

Folks,

My son's 2004 A4 recently started doing two things, which *might* be unrelated:

* Dripping clear oil 
* Losing coolant

Both of these things started happening soon after he changed the oil and 
replaced the stock exhaust with a Magnaflow. 


The oil seems to be very clean, almost clear, but with a slight pinkish tinge to 
it. Is manual transmission fluid pink? Never heard of it leaking.

We've checked for obvious leaks (engine oil, brake and hydraulic fluids -- none 
of which are pink anyway), but found none.  None of them are particularly low, 
except for the coolant.

The timing belt was overdue (96K), so I had it changed along with the water 
pump, but it looks like we're still losing coolant.

I'm baffled. Any tips would be appreciated ...

-Arun
