Hey

i have a focus that is causing me no end of trouble. 

First didn't idle right and would cut out now and again. 

The intermittent power steering on cold or dam/wet days 

Then all the gauges would fly up and down no power steering, turn it off and started all fine again. Then cut out all together rac called out restarted it.

Had a new battery & alternator. That worked for a week, but engine light was on.

monday loss of power steering while driving, all haywire with the gauges again. Power steering wouldn't come back on. Left it an hour all was fine. 

Next day went to start it all dash lights flashing, multiple malfunctions and it's died. 

Garage are saying it's down to the pcm! 

Any advice?? 

 

Anyone??

all i can recomend you try is check the body control module (fusebox in passengers foot well) connectors for corrosion/water ingress.
the garage you took it to was a ford dealer?

Yes it was a ford garage. The alternator is not charging the battery now and it keeps dying. 

Friend at ford, said they are not 100% sure changing the pcm will fix the problem. It's a lot of money for it not to work. 

Thinking of taking it to a auto electrican. It's arking out somoewhere too! 

Haven't even had the car a year either 

the control for alternator is via pcm, but the command comes from the bcm and the bcm relys on the battery monitoring sensor that should be attatched to the battery terminal. could be any of those 3 items at fault.

Thanks will give it a try! 

Hi I've been having something simillar happening with my 2012 focus my battery light comes on and off intermittent then all my warning lights come on i lose power and i break down but once jump started everything ok i was told the fault was a software issue but since arnold clark have been dragging they're heels i was told fault light had to be on took car in with light on found problem said nothing was wrong with the part then turned car off which cleared light now I'm left driving a car i don't feel safe in untill it happens when I'm near a garage for them to carry out a 2 hour diagnostic check fault code is U012d88 does anyone know anything about that 

Hey Lesley, ur problem sounds very similar to mine. I am to like you very wary of driving it. Thinking of taking it to another ford for a second opinion.

my light isn't on when u start the car, just while driving on and off. I had a software update back in march.
