    I got a used steering power box to replace my original one. well, problems solved almost,
no sound and not loose anymore, but there is a brand new problem as my original steering

box has no speed sensor, but the new one has a sensor. without the sensor then would be

a tough job to drive you know. so I took eletricity from the headlight first, then computer

shows fault code is headlight/field vision.  then I took electricity from the ignition coil, well,

the computer still shows the same message. even I removed the fault code via computer.

now, here is the delimma, how do I get the electricity for the sensor and without noticed

by the ECU? is it ok to take electricity from the ignition coil without any nagetive effect?

I assume you've got a steering box with the servotronic assistance when your car doesn't have servotronic?

I'm not sure you'll have a safe level of assistance for high speed driving if you just wire the solenoid permanently on, which I assume is what you are trying to do?.

I would either fit the correct steering box or retro-fit the servotronic module to control it properly (it only needs power plus a speed signal from the ABS ECU.

yes, all omegas are 2.2 elegance imported to china market. I think you're right and that is a servotronic steering box, you just need to give it power then it works. the problem is that I have no idea where to get the power for it without noticed by the ECU. as the car was not servotronic steering box. you meant I should get power from the ABS ECU for the steering box?  sorry for my poor english

[Kevin Wood]

The point I was making is that you don't just have to give it power.

The electrical connector on the steering box is a valve that is normally modulated by a separate control unit according to the vehicle's speed. To use it safely you will need the control unit from a servotronic car, which normally lives under the dashboard.

If you don't have the control unit, you will have too little assistance with the valve deactivated (as you have found) but you will have too much assistance at high speeds with the valve permanently wired on.

I think Kevin is saying that just simply providing power to it will give full assistance at all times rather than speed related assistance.Full assistance at speed is not desirable and potentially dangerous.Sounds like you need to install the other components of the servotronic system so you have speed sensitive assistance as per the original design.

Must type faster................

  Yes, Kevin you're right. but if I dont give power the the valve, then too much assistance for the steering box which is unacceptale, while moves smoothly if connected to the power. if there was no chioce then I have to let the ECU show the message. coz my omega has no that control unit as you mentioned under the dashboard. by the way, is it ok for me to get power for the steering box from the ignition coil..?


 thanks indeed.

if I need to get that control unit for the steering box, so what the code # for the unit? I dont think I can get it from china market as people even in Opel 4S dont know about it. anybody has any idea about it?

I was thinking fixing the original steering box but sounds impossible as no fix parts available in china but only getting a brand new one. too expensive as I mentioned.

No, I think you will need to fit the control unit. Or use the correct steering box.

how it works....

a servotronic steering box is different to a normal steering box.

steering pressure from the pump is about 10 bar. In a servotronic box, the electronic valve opens to waste some of the pressure, the faster you go, the more pressure gets wasted. The result is that you get heavier steering at high speed. Also if the valve stops working, the steering goes to "heavy"

in a normal steering box, the main steer valve uses the pressure a little differently, but there is no electronic valve.

If you use a servotronic steering box without the electrical valve connected, then your steering will be too heavy.

If you connect the valve to a permanent 12V feed, then the steering will be too light.

The servotronic valve MUST be connected to a servotronic relay using the correct wiring.

almost got the picture about the steering box with valve. seems I have to get help from

the opel 4S but really I doubt they can solve it. is it ok to provide the permanent 12V

power to the valve from the baterry?(the steering box works normal and the strenth is

acceptable as long as you provide power to it.), any NAGETIVE to the valve or the baterry

will loose electricty too soon, that's what I concerned about. Getting a brand new/correct

steering box? forget it, it worths almost 2,000USD. the spare parts are really bloody

expensive for Opel in china, geez.

thanks for all

   I wondering if any friend can help me get a proper steering gear box for my omega, brand new or remanufactured both ok.

  really cant get any positive help here

cheers
