Hello all. New here and hoping someone can point me in the right direction please. I've been trying to get to the bottom of a parasitic battery drain issue. Here's where I'm up to:

Car is a  2014 Zetec S 182.

Radio part number is BM5T-18C815-HN

Central display part number is EM5T-18B955-BA

Battery went flat, doors wouldn't even unlock. 

Brand new Yuasa EFB battery fitted, as at the age of the car and that fact that it stands a lot I just assumed it was the battery at fault.

Use car daily for 3 days on only 3 mile commute, no issues.

Leave car stood 3 days, new battery is flat, doors won't even unlock again.

Charge battery, test alternator is charging at 14.5 at idle and 14.8 when revved.

Test for battery drain and there is a ~2A drain when the car is stood, everything off and locked up.

Sat inside car with everything off, I hear the CD motor goes every 20-30 seconds as though it's trying to take a disc. So then I suspect the radio is faulty.

Remove the radio, the drain drops to ~300mA, even after standing over night. So still too high.

I leave everything plugged back in but remove fuse 67 which is "Information and entertainment display, GPS, Bluetooth phone voice control connectivity", after 12 minutes when everything shuts down the drain drops to a more normal ~10mA.

So now my theory is that the Bluetooth module is faulty, and is also keeping the head unit awake. I want to unplug only the Bluetooth module and see if that resolves the battery drain, but, where is it? Is it even a separate module or is it part of another one? Googled this to death and can't fine anything useful about mk3 battery drain. Any pointers of what to look for or disconnect much appreciated. 

Yes the bluetooth (or SYNC) module is separate. On the fiesta it is above the passenger footwell. Remove that trim piece (2 clips holding it up I believe) then the module is attached to that trim piece. The focus should be the same since the radios are the same. Don't see where else they'd hide it.

Thanks for the reply but it's not there on the Focus. I've actually found it, it's behind the header control panel, and now I've been able to unplug it my battery has gone.

For anyone following this later, the part number fitted to my car is D1BT-14D212-EB. A new one from Ford may have a later part number, and the price quoted today is £287.14.

Sod that hahaha. They're £50 tops on ebay last time I checked.

D1BT = Sync 1.1 module (adds music track info and a couple other minor bits). This was fitted 2014 onwards. 

AM5T = Sync 1.0. Fitted pre-2014.

Both parts are interchangeable just obviously a little more functionality out of the 1.1.

Bought a D1BT for under £25 off eBay 👍🏻

Fingers crossed it works when it arrives. 

Reading this post is such a relief. I have a 2014 Kuga with the drain issue. It is most noticable in cold weather so i've been testing with Fuse 67 removed for months now and i am 100% sure i have this issue.

my plan is to buy the D1BT part second hand from ebay and try to get one from a much later vehicle so that its less likely to have same issue.

Does anyone know where in the Kuga it is located? ive watched some videos which suggest behind the radio but im not sure.

any help would be great. and THANKS so much for the above posts... its so so so helpful

Same issue on Ford Fiesta 2014. 25k miles only.

3 batteries and Ford dealer repair later, and nearly £800 down - I have my fingers crossed.

The Bluetooth sync module is connected to the central media console. It also powers it, so you have no choice but to replace it.

The module is a small black credit card sized piece near front passenger foot well.

Whether you use Bluetooth or the media center or not it is a dodgy component that needs replacing otherwise it will drain your battery within days when your car is off. 

Very unreliable and shoddy engineering here. 

I had no choice but be ripped off by the dealer as they need to program the module. Otherwise you could keep on buying new batteries or charge your battery nightly like a mobile phone.

Bizarrely the Replacement costs £110 more if you dare ask for the broken one back to examine. A surcharge?? Are they hiding something here ?

Its really poor show. I'll never buy a Ford again. Shame as the mustang looked nice, but I'll look at other manufacturers now as a result of this experience.

Yes, I have lost £800, but Ford have list a £50,000 sale and all the servicing etc.

Bye

That's not true.

Neither is this.

Replacement modules are around £30 on ebay and take minutes to fit.

I don't get why people go to the main dealers and then moan when they get charged over the odds.

I doubt it us true too, but what I am advised by the official dealer. At the risk of having several more issues and being left stranded by mysterious flat batteries, I took the hit.

Note an independent garage were also quoted over £300 for a new bluetooth module. Then it needs programming. 

The independent garage turned the job down, saying let Ford do it and when you get the next weird issue go back to Ford.

Getting a 2nd hand module on ebay could lead me to needing a new battery again !! Ford have by short and curlies here.

Its odd that many people report issues with this 5p bluetooth sync component, but Ford refuse to acknowledge it is a poor quality component or issue. I never even used bluetooth! 

Like I said , I have been mugged for £800 in replacement batteries , diagnosis cost plus replacement Bluetooth sync module. 

But Ford have lost out on a £50,000 + servicing sale as I was interested in the Mustang.

They lost out solely because of a Fiesta bluetooth sync module 🙂 I'll  ho to Tesla instead.

HI m8 did you ever get to the bottom of this issue i.e. did you replace the Bluetooth unit and where was/is it? Any and as much info as you can give will help many owners  with the same battery drain (parasitic drain) on FORD KUGA (I own a 2014 model too).

 

cheers...

Hi,

I have D1BT-14D212-CC fitted to my car, would changing to D1BT-14D212-EB make any difference?

I have a similar battery drain problem on my car, has killed 2 batteries so far. For some reason when I do parasitic drain test it only shows 100-110mA drain though and I can't find a fuse that drops it. My theory is after I remove the battery cable, it resets/puts to sleep whatever was causing the battery drain. And then eventually will drain the battery again.
