Steering Assist Failure Warning

[Ben90]

Hi,

I have a 2007 Ford Focus 1.8tdci. Last week I got an intermittent message displayed on the dashboard saying 'Steering Assist Failure'. I didn't see it for a couple of days but then, at the beginning of the week, it came on again and hasn't gone off since.

I've topped up the power steering fluid and had the power steering pump checked by a mechanic and he said he can't see any problems. He also plugged it into a computer but couldn't get an error code because the engine management light wasn't on.

When I'm driving it under 20mph the steering feels heavier than usual. Above 20mph the steering feels lighter than usual. The mechanic said it's probably a fault with one of the sensors controlling how much power steering to give relating to your speed.

Has anyone had or heard of a problem like this and how should I go about resolving it?

Thanks in advance.

I had the same problem a few weeks ago. The message was displayed for around 10 sec. It never appeared since and I have driven 700 miles. When i did the dashboard diagnostic, I got a dtc: E196. Look at my post:

I have the warning message constantly on now, as soon as I start the engine.

I took it to a Ford dealer and they said its a problem with the angle sensor which tells the computer how much assistance to give to the driver. They're going to look at it on Monday.
