The eps light comes on in my dashboard and the steering is very stiff to turn, am told that i need a computer for the electronic power steering could u help me to source it, have searhed the net and cannot locate this part

It won't hurt to drive it. Steering will just be stiffer without the power steering. Once you are moving, it will be easier to steer.
Don't know the problem, a shop will have to check it out. But it is okay to drive it.

electri power steering assits is bad.. needs looked at...the motor that helps turn the wheels is not working..

EPS is Electronic Power Steering.

When the light comes on, it is a warning that the Electronic Power Steering system is having a problem.

The increased force you have to use, is because the EPS is not assisting you as much as it was before, if at all.

Here is a link to a video explaining the basic operation of the electronics at youtube.

Check the alternator,make sure that you have a good charging system,there is a fuse t the battery (+) inspect and make sure that the fuse has not opened

EPS indicates Electronic power steering warning light.---------The power steering needs to be inspected.The power steering pump, the power steering fluid, the power steering hose ,power steering belt and pulley. Get your car scanned by the dealer or at local car garage.That will be much helpful.As you will receive codes, as per codes you can replace the part or get the part checked.A fault in the wiring loop causes it to short on the steering column.This problem is very much noticed in Hyundai cars.-------

This will solve the problem or point you towards the cause of problem. Thank you for using fixya.

EPS stands for Electric Power Steering. Hyundais have electric power steering instead of belt driven pumps. But they still require power steering fluid, Check the fluid to see if it is low. That would trigger the signal to come on.

Most likely needs power steering fluid.

vauxhall charge 47 pound to look at the car for you sounds like the steering rack but i cant be sure, i would take it to vauxhall cause a backstreet could get it wrong and it would cost you more

EPS is activated only when the driver steers the steering wheel, thus reducing energy loss compared with the hydraulics. Its modular design allows for easy assembly. EPS consists of motor, electronic control unit (ECU), torque sensor and steering gear.
Our unique control algorithm allows for improved handling. Compact, light weight. Capable of controlling motors from 25 to 80A. Standardized column integrated or stand alone ECU.Basically its a electrically power steering to assist the driver to turn the steering wheel. Check the electronic control unit(ECU) for any short/burnout and the wiring should be pliable. If not then proper amount of current is not reaching the motor.
The light can light up if there a failure of the motor or any sensor is activated when this circuit has any problem.
Get i checked & repaired from their authorized Dealer and also get a service warranty for the part replaced as per norms out there.
However repair immediately otherwse you might find the steering wheel turning in haphazard manner or it could get locked while driving! .........................................sodeep
