Hi all,
I heard some noise (at the passenger side of engine) when turning, so I went to dealer and bought 1 can of ATF, to try to add fluid. But I couldn't open the green cap at the reservoir of the Automatic Transmission Fluid.
We are the original owner and we've never opened this cap before.
Our car: 2003 Audi A4, Quattro, 3.0 liter, B6 body, 48000 miles.
Please show me how to open the cap. And how much of fluid to add?
Help is appreciated for this stupid question.
Thanks.

 

there's no place to fill the trans fluid, and no dipstick either. Is this green cap close to the front of the car? If so it's the power steering resevoir.

 

as far as i remember the green cap covers power steering

 

That's right. The atf fluid is checked at the inpection plug (similar to the way manual transmissions are checked)

Now you said you heard a wierd sound while turning, which sounds like it probably is your power steering. You also need to buy that fluid at the dealership. That would be the green cap you see, like stated above. It should just screw off. If its hard to get off, try using a pair of pliers to get some additional leverage on it.

As far as how much fluid to add, there is a dipstick attached to the cap that tells you how much to add.

 

But dont use anything but the fluid from the dealer. You cant use ATF as power steering in these cars like you can most others.

 

You're right, this is about Power Steering, nothing related to ATF. I'm sorry I confused myself. I actually bought 1 bottle of Power Steering Fluid, not ATF.
Car is in body shop now, because of a door scratches. When getting it back, I'll try using a pair of channel-lock pliers to turn opening the green cap, which located next to windshield washer reservoir.

 

you heed CHF 11 or something like that

 

It is P/S fluid. If you can not open it, drive by the dealer and ask them to open and fill it up for you. I don't think they charge you any money.

 

nm....

 

just use a little muscle twist twist
