Title: C3 Power Steering Control Valve
Post by: 69CVET on December 28, 2014, 10:38:09 AM

Hi Guys
Just replaced slave cylinder and all hoses after a blown seal a few weeks back and all good back on the road. BUT...... Still not happy with the Control of the steering at over 90km/h it's like a dead spot where it will drift like the valve spool is fighting for the neutral spot and I have to fight for control in that zone.
Turning has no issues it's only in straight driving lines. Before I go and purchase a new control valve is there some adjustments I can make from that top adjustment screw ????????   Is it a adjust and test procedure ???  Happy to hear some feedback on anyone who has attempted this. Cheers

If you remove this cap from the end of the valve. It’s like a wheel bearing cap, you will find the adjuster.
