Noisy PAS

[Drummer87]

Just been outside to start car up after its been laid up for winter.

And I'm greeted by a noisy pas pump. Is this common with our cars?? Would tightening the belt help or the pump seen better days??

Yeah my new Avant makes a bit of a fart like noise when turning the wheel left at low speed, I take it this is curable?

pump rebuilds well documented on here although youl have to be brave!

[Drummer87]

Hmmm mines on idle could be cold. Sounded alright after a 15min warm up

[QuattroFever]

I used to get a clatter/rattle from my old one when cold

Mine also makes a groaning noise only when turning left..

Mine too, although it seems to happen more when going uphill, when you have to add a small amount of throttle. Actually, you can provoke the groan by accelerating very gently and turning left slightly... never fails...

WD40 + belt = hapiness

[Drummer87]

I read wd40 you shouldn't spray as it eats into the belt over time shorting the life span

Can't say I've had any issues in 8 years...

it also eats whishbone bushings ect.

My pump has been noisy for 140,000 miles, especially when cold but is still going strong.

probably just needed a run to let the oil thin down and lubricate the bits and pieces. Wouldn't worry

[Tonybolony]

I changed the PAS oil, and it made quite a difference to the pump noise when cold, also gave more braking and steering assistance. (I'm sure it's not my imagination)
I also tried WD40 on the belt,(and it worked) careful to keep it away from the cam belt- not sure I would want wd on that!!

steering pump

I had a coupe for 12 years and in the winter pump was noisy,and summer it was quite. +sprayed with wd40 which works.Always said i wanted to replace when it died but it lasted the 12 years i owned it with no operational issues.changing steering fluid helps too.
