Richard, yes, the old memory failed me :roll: :oops: Must be getting old.. Indeed my V6 gets it's act together very rapidly. So quickly you'd almost think there was a problem...

Will, no the V6 pump is unique to the V6 due to the different steering rack fitted. Memory again fails me but if you fit a V6 pump either the steering will be incredibly heavy or your steering ram will take off into orbit or vice-versa... Whichever way, it's not recommended :lol:

Electrically driven. Possible but it might need a fair old motor and a way to shut it off when up to pressure. Not worth the hassle really I'd have thought. Besides, waiting for hydraulics with a quietly idling engine on the first start of the day is doing the engine a huge favour...

Just thought a small electric motor could power the pulley and leave the pump to do its work and as it would kick in when the door is opened with the electrovalves the suspension would begin to rise and it could set to the pumps optimum revolution as well for best pumping power.

This would then leave the PR to do the normal work of pressure managment and the rest of the system to do its own work as well bar the hydractive rams which are controlled thru their own ECU IIRC which likely on powers on when the ignition is set to run position??

That "small electric motor" will have to be able to pump to a minimum of 150 BAR as the pressure regulator cuts back in @ 140 then out @ 170 BAR, ever felt the pressure required to pump up tyres using a manual tyre pump and even then its only up to say 3.0 Bar maximum so the electric pump will have to be very powerful.

The only way you could do this is to cut into the pipe running from the pump to the regulator with a "T" piece and run the pump from there, do you really think its worth all that? Its not as if Activa's aren't complicated enough already :lol:

Possible, yes, desirable, not in my opinion when all you have to do is wait a minute.

Im with Dickie on this, if it aint broke dont fix it matey. I agree its annoying waiting an age for the stop light to go out, but its a lot of work to even attempt to sort imo.

Ahh htere is some confusion i think here.

I do not mean replace the current pump. I mean hav an electric motor drive the current pump. This way it could be located closer to the PR valve and out of the way of the alternator as well. IE a motor that would bolt onto the flywheel of the pump :)
