Is there no power steering fluid in Audi A7?
I know Audi A7 employs electromechanical steering but does that mean it has no power steering fluid or a pump?. I can't see to find an reservoir tank for the fluid - if there is one.

The electro-mechanical power steering does not have a traditional fluid reservoir since there's no fluid.

Tenspeed, that's interesting to see. Maybe it's only on the newest cars. I don't know what model year OP's car is.
From Audi website (Germany):
The differences among model lines stem from the technique used to generate the servo power. The A3 and TT families and the A6* and A7 Sportback all have an electromechanical solution on board. An electric motor generates the steering assist, and the system requires no hydraulic components at all. It consumes no energy when the car is traveling in a straight line, saving as much as 0.3 liters of fuel per 100 km.
The electromechanical power steering is integrated with the sensors of the ESP stabilization program. To mitigate the danger of skidding, it automatically makes slight corrections whenever the car is at risk of deviating from course during braking. It stops the driver from making steering corrections that would make the situation worse by temporarily reducing the power assist. Accurate corrections, on the other hand, are facilitated with increased servo power. Using the electromechanical power steering and attendant ultrasound sensors, the A3, A6 and A7 Sportback all back autonomously into the parking space during reverse parking.
In the A6 and A7 Sportback, the electromechanical power steering can also be equipped with Audi active lane assist, which helps the driver to stay in the lane. The park assist system in the full-size models is also a particularly powerful function.
The compact A1* makes use of its own technique – electrohydraulic power steering. Here a map-controlled electric motor delivers power steering fluid to the steering gear. As speed increases, the speed of the electric motor and thus the power assist decrease. With high steering angles (when maneuvering, for instance) the volumetric flow increases, and so does the power assist....

Also, I'll be removing and installing the rack in my garage - any harm in removing the cross brace while the car is on ramps? It is only option that works for me...
