Hi, thanks for all the replies.
Yes, I am aware that the diesel version has an electric pump but that still uses significant amps & all power usage is an issue for me, so don't really want t use any PAS.
Didn't realise that PAS systems use a different caster angle. I could change that, but I guess there'll be no data available as I think all Mk6's were PAS & that would mean a lot of trial & error. Then there are other variables - I'm also looking for 4.5 or 5.0J steel wheels so as to fit narrower tyres. Less rolling resistance, lower noise & hopefully reduce steering effort further.
Currently I have removed the pump & connected the rack hydraulic in/out together. This avoids pushing the fluid through the pump but still has to push it back & forth through the valves. I was going to remove all the hydraulicy bits, but then wondered if the rack & pinion would get lubricated ?
