Power steering fault

The power assistance for the steering stops from time to time.If the engine is switched off and restarted all is well, Ideas ? Red light comes on


The car is a 55reg 1.2 petrol about 117,000 miles, I fear the time may be coming to replace it

Re: Power steering fault

I had this but did have the red steering wheel light come on too. New battery fitted and it's not happened again <touching lots of wood>

Re: Power steering fault

Weak battery gets my vote. Fit a cheap voltmeter and see what it's showing when the steering goes astray.

A new main earth lead (battery to engine and chassis) makes sense as they do corrode. Your car does have a high mileage so alternator brushes might be worn. Get the alternator tested.

Battery tests often come up showing ok when in reality the charge capacity is low. Make sure it's properly load tested.

Re: Power steering fault

Yep, its usually the battery, but I have just dealt with 2 pandas with dodgy main earth cables - oddly, both had just got new batteries!
(One owner almost certainly didn't need the new battery, but was Halfords-ed into it. The other looked like it hadn't had a penny spent on it in years, so probably did.)

So don't forget to check that cable too.

Re: Power steering fault

If the earth (under battery box) looks grungy it probably is. You can get new ones with crimped bolt eyelets for not much money at motor factors.

Re: Power steering fault

TBH even if it looks pretty much OK it may well be stuffed. On some you can tell by moving them a bit. They either feel notchy (broken bits of cable grating against each other inside the plastic covering) or produce green dust.

Easy to do on a 1.2.

Much more of a pain on a MultiJet.

Haven't done a 100HP one yet, but almost everything else under the bonnet on them seems to be somewhere between the hassle levels of a 1.2 and a MultiJet, so maybe only 2 skinned knuckles and some moderately bad language.

Re: Power steering fault

A jump start cable clipped to the engine block and battery negative will provide a sure connection that bypasses the original lead. If you can be sure it's solidly attached** you could leave it connected and see if the faults resolve.

** Not necessarily easy to do.

Re: Power steering fault

Battery and earth strap checked at local garage, battery had one dead cell so its been replaced. Hopefully this will cure problem, Battery only about 13 years old and not under warranty ! disgraceful


Thanks for the suggestions

Just noticed how "grungy" Becky's is whilst checking her over the other day after the new clutch was installed. I feel a visit to the Factor's coming on.

Re: Power steering fault

Earth straps look ok and can often be resistance tested ok. Problems show when engine start load is applied. If it's the bare wire plaited type looking rough, assume it's part of the problem and replace.

Make sure you get one with a good current capacity. I bought one listed as 'suitable for the 100hp' but it caused lots of issues and smoked on cranking. Turns out it was well under-rated.
