Hi Guys,

I started the car at the weekend with the steering on full lock and there was a real racket coming from the front. It was a definate tap/rattle and was relative to engine speed. I gave it a rev and it cleared, but as soon as I straightened the steering it made the noise as I turned the wheel. I reversed off the drive and after 10 yards it had gone altogether.

Every morning it makes this noise now and will clear once revved up a bit. This to me would indiciate the PAS pump?

I have had a small leak from the reservoir for a while, but the level is good.

Does anyone have an idea as to where I should look next? Do PAS pumps normally expire in a noisy fashion?

Any ideas would be greatly appreciated.

Ta, Platty

Mine did, but then I ran the engine without fluid in the reservoir

Electro-mechanical devices fail in whatever fashion suits them at the time.

it could well be the pump!! however i thought mine had gone screwy the other week(rattling and clanging and jerky assistance etc, turne out the belt was lipping under full pressure!! check it very carefully mate especially for wear in the tensioner bushes as this wil allow it to slip!!!

I will have a check for this OT, although the belt and tensioner pulley were new last year. I'll see what the tension is like and take it from there.

How much of a job is it to replace the pump?

Not too difficult, I think there's only 3 bolts holding it on. Remove the bagpipes from the induction. Drain as much ATF from the reservoir before you start, you'll still have more than enough left in the pipes to make a mess of your drive.

did mine on street neighbours went spare about the mess

just try bleeding it first.

jack it up and cycle between almost full locks about 20 times

then gradually move to full lock

then remove jack

don't try it on the ground.

hitting full lock takes the system from a normal running pressure of 50-100 psi straight to over 2000 psi
