Power Steering Grunting

Recommended Posts

Hi Guys,

Just a quick check, i don't have a leak on the PAS unit but i do get oil coming out from the breather cap on the reservoir thru that tiny hole there.

The thing is that it only grunts when turning left and not when turning right.

Is this an early warning to the box going to fail?

Thats funny we have the same problem on our P reg Discovery. It has done for the past 2 years and our mechanic has said its nothing to worry about. he said its like the layshaft bearings if they make noise they will make noise for ages before they completely go.

I had the very same thing happening on my 90-200 tdi I was told this was the return valve on the pump that makes it do that, I changed my pump over for one I had spare and it stopped doing the oil out of the reservoir thing
