Hi 

I have 1.6 tdcj focus 2014 

I recently been away for 2 week then returned home drove the car 50miles then when I woke up the next morning battery was drained to nothing no ignition lights or anything.

So got the car running but when i turned it off there is a high pitch noise coming from the egr valve which i understand is normal for about 5mins. So left car a couple of hour then went back lifted the bonnet and it is still making the same noise if I unplug the electrical plug to egr noise goes to a lower faint pitch but when reconnecting  it is back. I have also noticed that when I turn the ignition off the engine carrys on running until I open the drivers door.

I have spent hours googling and reading but nothing.

Any help/advise would be much apreciated

Thanks 

Sorry if I have posted this in the wrong place but I'm just new to this 

Update so far I took the car to auto electrician tested battery all fine.

Tested alternator said alternator is not putting charge into battery.

The thing is I have no warning lights coming on and I drove the car last night with lights on and stopped for half hour then it started straight back up. Could it be intermittent fault on alternator?

Or should I just get it replaced 

Thanks bri

#update 

So had alternator replaced no change.

This morning took drivers side wheel arch cover off to reveal the window washer bottle unplugged the top wires to check for water and yes there it was wet through left it unplugged. Returned to car to check the BCM and the water has leaked through onto the BCM I will upload some pictures so u can all see.

Hope this helps somebody out has it has drove me potty 

I have cleaned up as much has I could very gently with electrical cleaner just hope it hasnt gne too far

This is common problem with the 2012-2014 Mondeo, never seen it on a Focus before.

 

When u read into it all it is common upto 2016 on ford.

Another update 

I've  cleaned it up put it back together now the engine stops without issue and this morning it hadnt drained my battery.

1 thing I did notice was seatbelt warning wasnt working apart from that all seems good 

Haven't replaced washer motor yet so left it unplugged for now 

Been a month since I started this topic still not replaced washer motor yet but no problems since I cleaned the bcm and plug seatbelt light sorted itself out after a couple of hour.

So so far all is good just need to get round to replacing the screen washer motor 

Hope this saves a few peoples heads hurting

Brinsky, just what is a BCM?

Bobsparks

BCM = Body Control Module.

It's integrated with the passenger compartment fusebox.

Thanks for the suggestion.

This noise is intermittent, it seems to have gone away for now. I don't use the car much, only check it when my wife has issues. I was just re-parking the focus and noticed the noise. I am persuaded: "if it ain't broke, don't fixit".

Thanks for your help
