The PAS pump on my facelift 2.5 is dying.  Almost no assistance at idle revs, but ok when at 1000 rpm+.  Fluid level ok and it's not F14.

The questions are:-
1)     how much of a messy pig is it to change
2)     Are all V6 pumps the same ( and is it the same as a 4 pot one?)
3)     What would I reasonably expect to pay for a good used one and has anyone got one?

If your pump is bolted on from its front face it's messy but straightforward, there is no need to remove the compressor.

Some pumps have threaded holes, these will need drilling out to clearance size for the bolts.

The pump I bought for mine had its inlet stub at the wrong angle, the pipe could not be fitted.

The stub is push fitted with some kind of adhesive, quite a lot of heat was needed to soften the bond and rotate it.

Have to say I was quite concerned about that, a pal tells me this a common way of realigning pipe stubs on Rotax aircraft engines and not to be feared.

It all works well with no leaks.
