Please, just tell me what is it supposed to contain in the lower right corner, with the green cap?

On an Audi 2002 A4.

Take a look at this sample picture I found on the net.


Mine is totally empty (bought the car this way) and for obvious reasons, would like to fill it up with (not sure what it is, double question!) "mineral oil".

Thanks and do not laugh

RiCK!

 

Where is the picture?

 

emmmm, well, right in this page?

For an obscure if you cannot see it, here is the link :

Thanks in advance!

 

It should say on it "use only mineral hydraulic fluid" If thats the case then its the power steering fluid and if you unscrew it there is a dip stick in it.

Please confirm?

Maybe there is a mechanic out there that can also confirm.

 

power steering fluid.

 

Okay, thanks that's I wanted to be sure. Indeed, I confirm that I saw "use mineral fluid somehting something".

That leads to my last question, is an Audi's power steering fluid different that the one we see in each and every garage?

Thanks !!

 

Pentosin 11S Synthetic Mineral Base Audi Power Steering Fluid

Pentosin CHF 11S is a special proprietary synthetic mineral high performance Audi power steering fluid. This power steering fluid is designed for extended mileage interval changes. This fluid is unique in its ability to maintain consistent viscosity in extreme operating temperatures from -40°C to over 130°C.

This is the top line Audi power steering fluid, especially designed for hydraulics of the highest technical requirements
Equivalent to Audi power steering fluid part number G 002 000 (G002000).

 

Simply for reference Audi has replaced their OEM G2000 (green) with newer G4000 (brown). The packaging says the two can be mixed although personally I always flush out the old and install the new.

Ricke666 - are you hearing power steering pump cavitation whine sounds?
