Focus Power Steering Assist Failure!!

16 posts in this topic

In need of some advice guys,

I was driving home and had the warning lights on the dash go off! then the following message "power assist failure" then my steering locked up and was crazy stuff, i really struggled to get to a safe place. I turned it off, then back on after five mins then drove some more because i was so close to home and made it to the last corner and it locked up again?

i was looking around her for a while and finally discovered that the battery light came on which prompted me to look at the fuse box in the engine bay and there was a a badly corrosion fuse which happened to the the battery smart charging fuse?

so i know in the 1.8 TDCI the power steering runs of the alternator not the engine belt, so would the crap fuse cause my battery to drain due to poor charging and there for cause me power steering to mess up? getting some new fuses tomorrow when the shop open!

Really hope this is a easy fix!

Any advice would be sweet!

P.s my power steering fluid levels is spot on lol :)

Anyone got any other ideas? The steering seems to work fine for a while then just lock up?

Thanks

are any of you using an OBDII adapter? if so remove it, I had exactly the same issue on my CMAX, I started the car with the phone listening to the car through the OBDII bluetooth device, warning lights, car juddering, refusing to accelerate, steering locked. Disconnected the battery (thinking it was an ECU fault) took out the OBDII and started the car with no issues. Recently it happened again on a garage forecourt, I just took the OBDII adapter out and everything returned to normal...

Its a basic, so check it if you have one of these adapters :)

most mobile mechanics will come and have a look for free, but you probably will need a tow at least. If you have a friend with a tow rope and can roll it to an appropriate garage, thats your best bet, but it does sound like pump or pipe is the issue unfortunately.

I thought the power steering on the later Focus diesels was partly electronic, so any battery or charging issue may be linked.

well i have sorted mine now............. i got a friend to clear the error codes then took it to a dealer and swapped it for a brand new zetec S,

But on a more helpful note ford said they couldn't pin point the problem! is was costing me a small fortune to just find the problem!!!

Then a friend of mine suggested a home mechanic who looked at the car and advised me to sell it due to a list of error codes longer than my arm, the guy knew his stuff and he had some amazing computer that ran tests and he got stuck it the old fashion way to!
