Hi all,
I have noticed that sometimes at low speeds + low engine revs e.g. when parking up, the steering suddenly goes rather heavy momentarily, as if the assistance has cut out. With a few revs it comes back in but can go again. Its fine when driving with any speed/revs. I have checked the fluid levels and it seems fine. Any ideas on what the problem might be? :-/
Regards to all.

Sounds like the power steering pump to me - assuming the fluid level is OK?

Yeah the fluid looks fine, cant see any leaks anywhere either :-?

Mine was the same, a 'new' pump from Marky Mark sorted mine out. :y :y
-
Yup, power steering pump, that's what was up with mine, new wishbones wouldn't hurt too.
-
two questions:
1) Whats the millage
2) Does it only happen at slow speeds when the revs are low?
-
The mileage is 120K.
Yeah only happens when the revs are low e.g at idle and low speeds like when parking up (when you really need it! :-[ )
-
Check your tyre pressures on the front (naturally!).
Low pressures give the P.S. a hard time.

Try changing the servotronic relay in the driverside kick panal, as this is part of the system that regulates the assistanc at various road speeds. It is cheaper than the pump and easier as well. :y
-
I'm having the same trouble with the pas and mine is also really noisy when i'm on a hard lock. Ive looked new pumps on ebay but from what I can make out there are a number of different ones.

RELAY!

How do you identify this? (assuming it doesn't have servotronic relay stamped on it in flourescent pink ;D)

I have just changed one on a 3.2 elite 02 plate and it was red in colour, pm andyc for the part no and correct one for your car year model ect. My memory is really bad at the mo but i think it was the only red one there. ::)

A bit of noise on full lock is normal. if its REALLY loud then mayeb something is wrong.

Good advice will try all the above :y cheapest first!

Strange, the 'servotronic' unit on my 1998 2.5 petrol Elite was/is located up at the back of the glovebox and yes it is 'red' plus it has 'SERVOTRONIC' printed on it, two other relays are near by.
Full info from the top down: C3 ZF Sevotronic 7038 900 210 GM ZR 90 459 301 3x5 624 16/96 (this is a spare) yours if you want it :y

well well, decissions decissions. I have had servotronic relay fail, and only played up at speed,no reason why it wouldnt play up at any speed i guess but with that in mind would tend to think pump, but with a free relay to try i would give that a go first, obviously, if you had to pay for it, (£70 iirc from vx) i would want it verified via tech2 first or you may end up paying for both relay AND pump.
Oof to the rescue, try the relay and go from there. :-)
-
Send me a PM with your address if you want to try this unit and I will post it :y

Thanks, will have a look and let you know :)
Forgive me for sounding a little thick, but what does the relay actuall do to the power steering pump? :-?
-
It controls the amount of assistance that the rack gets at different speeds and lowers the assistance at higher engine speeds.
