Peugeot 4007 with parasitic battery drain - unknown cable? Sign In

Hi,

So I have this 2009 Peugeot 4007 which has been struggling with battery drain over the last few weeks. My first quick fix was to buy a new battery, without any help.

After following a couple of videos on YouTube, removing fuses and so on, I found the problem area - or problem cable&wire if you will.

It is not a fuse, but a cable attached to some kind of box on the positive on the battery.
See pictures, where the last picture I have marked the cable:

When disconnecting this cable from the +, my multimeter dropped from about 1.256A to 0.

I then bought a service repair manual for the car, trying to find what this cable is. All I could find was that it is shown is this picture, without any further explanation:

So the big question is; how can I find out what this cable does?

This vehicle isn't sold to the US leaves us limited. Just at a glance, last pic that would show: Nope, too big.
Anyway, there's a LOT of stuff on that cable! Just one question since you seem to have some clue how to find a drain is when hood is closed is there something that can touch all that stuff? If sound insulation or able to ground it might only drain with hood closed.


If wet would be faster.
There's a broken, red shield for a purpose and another IDK thing suggests there's aftermarket something installed in this. Whatever it is, is much more likely the source of trouble if only routing wire that finds a place to rub or plain touch ground?


This battery may not be under the hood (it's not sold here) so whatever covers it wherever it's located for the first guess,

Ah - I didn't think about that. Maybe I can try a UK-forum. Norwegian-forums are pretty limited I'm afraid :-)

Yes - on that white "box" that is supposed to be covered by the red plastic, there are a total of 6 cables. 4 of them comes from underneath and is secured in the back of the white "box" with separat fuses, and then the 2 cables - which is mounted on each side.

Nothing is touching it when the hood is closed.

The only aftermarket equipment installed on this car is a DEFA WarmUp kit. However, this is not the cable for it.

So from what I can tell, the connectors on the white box are original, also when comparing to the PDF-file from the service manual.

Those are all main fusible links, usually for complete systems. Of course it will drop the draw. You are basically disconnecting the whole battery supply to all the systems.

You need to get to the smaller circuits to actually find your problem.

I understand, but it is only one cable that is acting this way. The other 5 does not show this level of amps drawn at all. Shouldn't this be the case with the other cables/links also?

And further more, the reading of almost 1.3A is way higher then it should be, even though it is for system components?

I have tried every fuse in the car, and this specific cable is the only one that has made the multimeter drop when unplugged.

I'm not surprised that at least one fusible link shows large current draw. Each one supplies current for multiple systems and until you isolate which specific system, you haven't found anything.

You also are not giving any of the timers sufficient time to expire.

Here is the proper way to look for a parasitic draw in the electrical system. This is a standard means of isolating a drain but as Tom advised you, we have no info to supply you on specific circuits and what specific fuses may operate.

There is a procedure for finding a battery draw like that.

You will need a digital ammeter and a jumper wire with clips on the ends to do this.
First rig any door switches so you can have a door open without triggering the interior lights and unplug the hood light. Remove one battery cable and attach the meter in series between the battery cable and battery post. Take the jumper wire and also attach it the same way. Leave the jumper wire on for at least 30 to 40 minutes to expire all the automatic timers. Now remove the jumper wire and read the meter. Anything over 50ma is too much draw. The way you locate this is to start removing fuses one at a time until the meter drops to normal level. This will be the circuit with something staying on. Determine what components are part of that circuit and check them individually until the problem is isolated.
Note that the act of pulling fuses will often restart some timers so you may have to wait for them to expire if that happens

MrGregert: You said back a few post ">The only aftermarket equipment installed on this car is a DEFA WarmUp kit. However, this is not the cable for it.<"

What triggers that to work? I take it that this is a diesel and it warms engine block so it will start.

No info but those type things are used where I am most OE to house/land power not use the vehicle at all or the ones I've seen.

There's the trouble, most likely, never sure but disable that bet you find you drain.

Hammer listed out what is a nightmare to hunt down even if you can isolate the reason. Reason #1 is near always some junk added after the machine/vehicle, car or truck was made.

HT as called also said you need to wait between checks for items to power down. What a nightmare finding these things are if only taking lots of time for some silly wire or how it tapped power? Might find you can do without that and really end this. It's been ages (not my thing meaning diesel anything) as it's cold for a few months where I am they stink and always did better if newer can't be solved the fuel goes to a gel doesn't move,

Resetting the modules and equipment, or letting it go to sleep rather, is something I missed in the YouTube-video I watched.

I just did it, and made sure every amp was going from the terminal, via the multimeter, to the post (- battery).

I started at about 1.017A after the car had gone to sleep. Then I started pulling fuses. No reaction on the fuses located under the hood.

However, when I started on the fuses under the steering wheel, I found the faulty ones. It is number 7 and 8.

7 indicates:
Audio Equipment, telematics, multifunction screen and bluetooth system.

8 indicates:
Remote control key, air conditioning control unit, instrument panel, switch panel, steering mounted controls.

When I pulled fuse 7, it went from about 1.000A to 0.600A. When I pulled 8, it went from 0.600A to about 0.001A.

So, I should now have located where the drain is coming from, but how does this work now? Do I need to replace every switch, instrument panel etc.?

The DEFA needs to be connected to an electrical socket for it to work, so it is nok like for example Webasto which uses the cars power and diesel. In addition, there is also an on and off switch on the coupe-heater inside the car.

This was actually the first thing I checked and was ready to tear it out, but since it's not the culprit I may as well let it be Laugh

My thoughts were strong guesses because you didn't say it was a diesel. Petrol or Gasoline fueled engines also come with heaters new OE.

You ruled it out? Now I ask if you use this device and please say what DEFA really stands for? Is that using a 220V line to plug into?

It's still in the game if plugging that in still IDK maybe it's causing a hot wire to touch another then quits it?

I'm trying to find this as much as you are seriously blindfolded the name Peugeot hasn't been sold here (it was) in freaking decades now for a vehicle nor a machine that I know of?

Don’t forget, you pulling fuses can restart the timers on some of the circuits.

Yes - it is ruled out because I have disconnected the 5A fuse for it. So as stated earlier, I have narrowed it down to fuse 7 and 8.

Hehe. Peugeot are maybe not as big over seas I suppose. DEFA is just a brand. They also sell in Canada, but is by far the biggest in Europe when it comes to car equipment like heaters, chargers, charging solutions for electrical vehicles and so on :-) This is the cable that is used If I want to turn it on:

Thanks for the tip. I did figure it may function like that, so I went to the garage and plugged in fuse 7 again to see how it acts after some time without fuse 8. Maybe smart to do the same thing reversed also.

Now seems you are on to or down to just 2 circuits. Great. If you do find which if in fact it is on 1 of those next find out all items that fuse covers.

If either of those has zero power when this thing is parked IDK where they have power from. Hard to know which of a zillion things have power or none would be helpful for owner's manual or serious wiring diagrams.

Places that can draw maybe more US luxo vehicles moreso is wiring through door jams and lighting that turns on automatically for vehicles even glove boxes, trunks, hoods many have power to sun visors it's nuts!

Tom

PS: Peugeot? Many makers just would re-tool up to US specs are difficult for crash testing, fuel consumption and of course emission controls whole engine types couldn't be just altered the 1970s were tough!

Re: Peugeot 4007 with parasitic battery drain - unknown cable? Sign In

Update.

I removed all of the panels and starting removing electric components.
To make long story short:

I disconnected the instrument panel (cluster?) and was hoping to see the amp drain drop. It didn't. However, for some reason, when I plugged in both fuse 8 and the instrument panel later (maybe 30 min), the multimeter read 0.40A and after 20 seconds, it dropped to about 0.003A. So I really have no explanation for why the solution was to un-plug and than plug in the instrument panel, but now there is no parasitic draw on fuse 8.

Regarding fuse 7, it was not the multimedia screen/radio. Then I noticed that in the Norwegian user manual one component is merely described as "handsfree". In the english however, it is also described as "bluetooth". This is when I saw the bluetooth-modul under where the multimedia screen/radio was placed. I disconnected this, and the multimeter dropped from 0.40A to 0.003A again.

When I plug in both fuse 7 and 8 now, with everything besides the bluetooth modul, the multimeter reads from 0.001A to 0.006A.

WOW! I think you found it? Good approach to isolating the problem spot or item.

Laugh - I have ONE (of 5) vehicles with "Bluetooth" don't dare put a thing in that expecting some explosion if I did so don't. It's also in a vehicle that pre-dates such things because no OE radio (new) was available in the whole world! :-) Tom
