Power Steering Fluid

[Redsheep]

I have changed the brake, diff and gearbox fluids, the coolant and obviously the engine oil.

Then one missing is the power steering fluid - which I believe is better changing the complete reservoir (with filter) - Question is is this worth it?
I have checked the reservoir and the fluid seems nice & clean but I would think it’s possibly original so 25 years old. No noises or groans from steering and drives fine.

I changed mine in situ.. good thread here. My post is about half way down. See the difference in the colour of the fluid versus new

A bit of power steering maintenance.

The one aspect of driving my Z3 that I've never been happy with is the steering. Its always felt like hard work and not smooth enough for really confident cornering. I've had an E90 and a F30 previously and these were very good in that respect so I thought the Z3 should be better. In the past...

If the fluid is good it is still pink. If not, it’s ready for changing.

I will take some fluid out in syringe to check colour properly.

As you left original reservoir & filter in place, did you notice any difference with just the new fluid when driving?

Yes it’s a lot smoother and the pump is now significantly quieter on full lock. I also lubed the joints on the steering column..that made quite a bit of difference to the feel. My Zed had only done about 1000 miles is the past 5 years when I got it and it was seizing up.
