ST-0wner

Having a bit of an issue with my 2008 Focus ST3. 52k


Out of no where it wouldn't start one morning, jumped it and took it for a good run. Several hours later dead again. Replaced the battery and it was fine for a week or two, started better than ever.


Two weeks later, out of nowhere, dead again.
Jumped it to get me going, left it a few hours, dead again.


Battery voltage whilst running - 14.5V
Battery after turning everything off (Ignition/Engine) - 12.6V
Battery voltage an hour later - 11.6V and failed to start.


Tried to identify a circuit drawing a current but no such luck.
Now its holding enough charge over night to start every day for the last week or two, sounds as though its struggling but still starts.


'Power steering malfunction' also pops up during every start up, but no issue what so ever with it.


Once the ignition is turned off, a good 5 minutes later it sounds as though things begin to close/open (Vents or valves or something??) and then settle. This used to sound like a whining noise for about 10 seconds, which now seems as though its struggling and takes a good 30 seconds.


Not a clue where to look now. Power steering? Another battery? Alternator?


Any assistance would be great! Cheers
