When driving the EPS light on the dash board come on and the sterring become stiff. when i turn off the ignition and start the engine again the EPS light come on and off normally and the every thing return to normal. The problem now occur more frequently. Please what can i do to solve the problem ?

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.

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.

i have just had this exact problem driving home did you find a solution ?

Most likely needs power steering fluid.

First you have to check power steering fluid level, and if it's ok then you have to check power steering pump. If you have a EPS light on your dash, then you have to plug a ODBII diagnostic tool to read code and then interpret what the problem is.

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

My EPS on my mitsubishi colt 2006 stopped working about 8 months now, I changed the electronic box,but it started to work for ten minutes and then stopped.I carried it by some electricians and they put the computer on it, but it is not getting through.Could someone lend some assistance!!!!!!!!!!!!!!!!!!!!!!!!1

start by getting a code read,it could be cranksensor or a fuel related issue,give me the codes and i will be able to help,the pd engines are very reliable and dont give many problems

Make sure the battery terminals are secure. Other than that I would guess there is an electrcal fault on the vehicle. I am not familiar with the beetle but think if I were driving your vehicle I would make sure all electrical connections were as they should be.
