Forum rules


When you put a new thread up in the Workshop please put your car's year and model in the post subject/thread title, along with just a brief indicator of the problem.

Car Year - Car Model: Brief description of issue. EXAMPLE- 1999 9-3. Problems starting when hot.

For Tech II issues or help requests please state the following in your title ''Tech 2 help required - state issue and your location ''.


Please also add as much information as you can about the problem, to your post.

This will help us to help you, without having to ask basic details such as what car you have.


Threads with non-compliant titles will be moved to The Pit Lane (in which no replies can be posted, but the OP can edit the thread - upon which the thread will be released to the workshop forum, note compliant threads will be moved back when the mod/admin team next visit the Pit Lane. if your thread has been sat in the Pit Lane for 24hrs+ after editing, pm Tech II to request release)

Nb. Generic thread titles for truly generic issues that genuinely are not model or variant specific (such as "how do I change the spring in an forge wastegate actuator") are acceptable

**The first 5 posts for new users require individual moderator approval (which they will only get it if they are in line the rules of the forum). Please be patient and allow time for that to happen, and avoid duplicate postings.**

Guys,

Seems like steering is flavour of the month for me just now. My Diesel 9-5 estate has very heavy steering when the revs are low. It's fine once I get above 1200 RPM but below that, assistance is non existent. I guess it's either the pump on the way out or the rack by-passing somehow. Any ideas ?

Starting with the easiest and cheapest......

How's the fluid, may be worth changing and seeing if it makes a difference.

With the assistance coming in at higher revs I wonder if the pump pulley may be partially seized and not turning some of the time (this is a pure guess!)

wgl2014,

Fluid has been changed ( three times ) by removing as much as I can with a 'turkey baster', refilling, running for a while and repeating. Fluid lovely and clean and clear. Pulley turns easily by hand and the belt has been replaced.

Was it changed for the correct viscosity fluid?
The viscosity has a direct effect on the weight of the steering.

Thanks,

I'll look into that. Don't have a diesel 'spares' car yet so it's a trip to the scrappy once the weather improves.
