I found 2 nickel sized drops of oil under the back of my 09 PDK S with 525 miles on it this morning. The oil is definitely green, I am thinking that it is power steering fluid.

Anyone have any ideas?

 

If it's mildly fluorescent green then it could be coolant. Don't let your dog into the garage until you have cleaned it up. It's poisonous and they love it.

 

Does Porsche use the green coolant or the pink/orange type?

 

Well oil is amber or brown if old, power steering fluid is almost always red. I just assumed that it would be coolant.

Unsure if Porsche factory uses green or pink.

 

Last gallon I bought from my dealer was pink.

 

The coolant is definitely pink. When I look under the car I see nothing! No visible sign of leakage??

I hope it's not the PDK fluid?

 

Has this happened more than once?

 

This is the 2nd time I have seen it. It does not happen all of the time...weird!

 

The coolant is certainly pink. Its probably PDK fluid =(

 

Perhaps power steering fluid?

 

Yes... you are correct. I did a little further investigation by removing the fill cap on the power steering reservoir and by looking in with a flashlight I can clearly see that the fluid which is Pentosin is bright green. I guess I will call my dealer tomorrow and have them take a look at it.

Also the fluid level is now a Min, just touching the bottom of the stick. I hope they don't have to change the pump. Maybe it is just a loose fitting etc.
