That is the power steering fluid reservoir. Even though the Caddy 2K is PQ35 platform like the Golf 5, some came with conventional engine driven hydraulic power steering, the fluid is green mineral fluid... what I call Citroen blood.
Thanks for your reply. The reason why I asked is that when I went in to my local auto store here in Australia and they did a search on their computer and there was no reference to this vehicle having hydraulic steering .
So you are pretty sure that it has hydraulic steering and not electric?
Do most caddys have electric steering and why did they make this model hydraulic?
Just need clarification. Thank you very much for your time taken to respond.
