Disco 1 Foaming steering fluid reservoir

Georgeblade said:

Hello,
My pre face-lift 200tdi has loss of steering fluid from the reservoir due to foaming.
Checked all connections - all tight with no leaks.
Steering pump makes a whining noise under load.
Is the pump a goosed?

Thanks for thoughts snd opinions.

The fluid is full of air, hence why it makes a noise when under load. Air is getting in some where, hose breaking down
oil seal or damaged header tank/cap seal ect. Now the pump is noisy its gandered.
Replace the all the old fluid & check the hoses an see if they are soft or cracked.

If air can get in then the fluid can get out, try bleeding the system, I understand its as simple so undoing the bleed nipple on the top of the steering box and then turn the steering one way to full lock, then the other way to full lock.
Anyway Ive never had to do it, even when replacing the fluid which I did a couple of years a go for the first time, but the full/ correct bleeding procedure is stated in the workshop manual.

Does the D1 PAS reservoir have a built in bottom screen like on the D2 PAS reservoir? If so, it might be clogged and foam up like on the D2.

The inner liner of the hose can break off due to age and clog up the screen.

I've never had that issue in my 36 years of using an identical system in my two LRs. Luck or what?
