Hello,
My '03 A4 1.8t Qtro 66k miles has a leak. I see the leak on the ground about the size of a CD when it's parked overnight. Now I'm not sure what fluid it is. It's not red, black, green or orange. It's more clear with hint of pink to it, it's almost watery than it is thick as motor oil. I can tell that it's coming from the center, passenger side of the vhicle. Anyone have an idea? Thanks.

 

Animal, mineral or vegetable.

There are very few fluids in a car...motor oil, coolant, power steering fluid (driver's side of the car), or condensation from the air conditioner (water).

check your fluid levels. Dip your finger in the fluid. If it feels slightly greasy and tastes sweet when you lick your finger it is coolant.

If it feels like water, and tastes like water, it is condensation from the air conditioner, like every other car with air conditioning.

 

Tasting it may not be a good idea.... Yes it does have A/C and I do know that condensation can cause water to drip from under the car; this occurs only if the A/C is used. I don't use my A/C and that thing still leaks. My guess maybe the power steering. I'm taking it to a Euro specialist tomorrow. LEt me know if anyone else may have a better idea waht it could be. Thanks.

 

My guess is sill condensation from the AC.

 

+1 for condensation....you can really tell oil apart...coolant smells like coolant and yes...does taste very sweet...hence why so many cats die every year from licking up coolant in the garage! power steering fluid is red but it feels oily!

 

Sounds like you aren't very intelligent when it comes to cars Mr. Jon. Just an observation.
