I know Rob

I got it through car parts conexion for £40 all in instead of £120

Same boat as I am in.

TIS2000 explains, remove plastic engine tray, remove heatsheild from steering box, unplug solenoid, remove 4 screws, and remove filter aswell, replace solenoid with cleaned filter, tighten screws to 2.5 Nm and refit heatsheild.

No mention of fluid loss, unless you'd expect it anyway?

Thinking of swapping mine out myself, as didn't feel any difference after purchasing and fitting new ZF servotronic relay from vauxhall at the weekend.

Will follow your post with interest!!!

If you replace the solenoid, let me know if it can be done in situ as TIS explains.

Cheers

Will do, but it won't be for at least a week now, as I need the car. Although I mite get the chance to jack it up and see if it looks remotely acessable.

[feeutfo]

Given the pics, and the non sheared off shear bolts. I do wonder if somebody's been in there before.

[TheBoy]

Gixer, reckon someone has changed the box? Wonder if an early one went on, and thus needing the earlier style confit programmed onto the ECU/Relay??

[feeutfo]

I can take a pic of the id plate.
Would that help? Not sure we know what to make of the various differences.

Although I am only suspicious of the disterbances inside the car so far. I haven't looked under it yet. It's too hot for jacking up cars.

(although they would have to move most of it to change the box I guess)

have the same trouble, pump broke up,pump changed, fluid changed. after a couple of dry turns assistance runs out.

had planned a look at the filter/ solenoid on the steering box and it looked as if the bits you need to get at are against the chassis/ box out.

edit . relay changed first with a good one from the Bristol boy

Wonder if its worth trying to program an earlier config

I'd need to check if its possible...

Best pic I could manage with a gay phone. Glare off the badge didn't help. Not to mention all the LPG gubbins some eejit put in the way. 


Digit under the rivet, bottom left is a "1"4817  -   0103 on the right.

No idea if this is of any use at all.

I can confirm you can accidently set the 'old' config codes to a 'new' servotronic, run for a few months, then set the correct code with no ill effects (or noticable difference actually)

Mine was at 010 (normal), then set to 007 (old code for min), then finally reset to the correct 009 (new min code)


should add, I have a steering box in the garage if you need any other pics for reference

[feeutfo]

Was aware there where 3 different codes for min med max assist. It is currently set to max assist, unless we have it arse backwards.

Well ya never know.

Thanks Jimbob. Might come in handy at some point.

blown that theory then

This should help you get your head around it.....

Every day's a schoolday! Ta very much for that, 2w - very informative.

Further to this, yesterday, while turning into Kevin's drive i noticed a squish noise from the pas pump, as if it was on full lock.

Except the steering was nowhere near full lock in order to make the turn. Revered back out on the same turning circle to repeat the sensation, and noticed the steering get stiffer, much stiffer, about 90 degrees of steering wheel movement up to full lock was impossibley stiff. This had caused the squish noise fom the pas pump, because the resistance had caused the relief valve on the pas pump to open, and did so long before full lock was reached.

After discussion with Kev we concluded a couple of things iirc.
1 the pump appears to be working fine, as it is generating enough pressure to open the relief valve at tickover speeds
2 the squish noise comes from the breather hole in the pas reservoir cap as the pressure releases.
3 the pas fluid was bloody hot. Only marginally cooler than touching the plenum after a blast. Not sure this normal tbh.
4 need to check we have the right pipes but the steering box cooling pipes where cold. The ones running across the front of the rad, behind the screen wash reservoir.

This is starting to look like fit another box.

[feeutfo]

On checking Opel oem the pipes are feed/return between pas pump and box/box to reservoir.

Odd they should be at ambient, and the reservoir be so warm to the touch.

[TheBoy]

I know on one of my previous cars (can't remember which) the PAS bottle fluid used to get quite hot. Someone explained the reason was because the pump is constantly pressuring it, causing heat.  No idea if this is correct.


Wonder if its worth disconnecting rods from box, and moving by hand, seeing if any tight spots, causing the pressure valve to open beford condeming the valve itself?  Esp as there is a suspicion this isn't the first box in that car?
