Hi,.

I am super locked out of my L320 2008 TDV8 and I have seen on other threads that I can charge the battery via the white 7 pin tow socket. I plan to use my battery charger to get enough juice in to the battery so I can open the car and pop the bonnet to replace the failing battery. I have purchased a 7 pin plug and suitable 3 core cable but can't figure out what pin numbers to use. Some user Doo has said use pin 3 for live and 7 for earth just to get the doors open when others have said use pin 4 for live. Can someone give me a definitive answer and a photo if you have one please. I also am not sure whether to set my battery charger to 12v or 6v to do this as I don't want to blow any fuses.

Thanks,

Adrian
 
I belive it is 3 for negative and 4 for for positive.
This is the normal for the 'supplementary or caravan' 7 pin socket.

Voltage doesn't blow fuses, current blows fuses.
Use a battery charger set to charge a 12V battery.

Thank you I will give this a try. I assume I should be able to unlock doors straight away?
 
If you search for the socket it will show you a view off the socket so you can see. Make sure it’s the face they show and not the back.
You need the permanent live not the switched.
If you just wire a good battery to the live and a jump lead to body from negative you will be able to pop the locks with the fob.

My intention is to put crocodile clips on the other end of the 7 pin cable and connect to the battery charger + and - connectors which should do the same as you are saying.

Not with a domestic type battery charger connected, you might have to wait up to 30 minutes for the battery voltage to rise enough.

Power is now obviously getting to something as the lights front and back are flashing away as if the alarm is going off so I guess this is part of the battery getting charge.
 
You could have just put the + of a multi meter on each of the pins in turn (with the earth of the MM on the chassis) & found the permanent live that way ;), hope you getit sorted.

Bit of a problem as I don't have a multi meter. The flashing lights have stopped but and battery charged is showing halfway but the none of the key fobs are working. I have one of those locksmith kits to wedge the door open so i could pull the lever but that didn't work today when the battery was completely dead so maybe it will work tomorrow with a bit mor charge otherwise it's call the AA.
 
If it's super locked, no amount of pulling the inner handles will open it. The AA should be aware of how to access the boot - clearly I'm not going to post it 'in public', nor in private to (no offence intended) someone who's first posts are about being locked out of a L320...

Do you have any idea what caused the flat battery? it may well be related to why the remote won't unlock the vehicle.

Yes the battery has been failing for a while and my mechanic mentioned it at the last service. It used to be my wife's daily driving car and our tow car but we bought a Q7 in March last year and my intention was to replace the battery, get it through the MOT again and sell it but I just have not bothered until last week when I bought a new battery but found out I couldn't open the car. This is why I bought the unlocking kit as I had seen video of some guy in the states access his the same way. I wasn't aware of the term super locked until I looked on Google for the issue today. I agree It's not the ideal first post but I don't normally do my own servicing etc and apart from paying a locksmith a few hundred pounds I hoped a £30 kit would solve the problem. I've sent you a PM if the think I'm trying it on or dodgy.

Quick edit in that it seems that the charging has put enough juice into the battery to enable me to open the doors and pop the bonnet so I reverted to charging the battery normal way overnight now. It also appears one of the fobs isn't working so I assume battery maybe dead but at least I'm in for now!

This happened to me and I found it was easier to do it via the rear number plate light. The terminals on that were easier to get the power pack leads onto.
Worked for me.
And all the idiots thinking it's dodgy, all this does is provide power to the car when the battery is totally flat and nothing - including the bonnet - can be opened. You still need the keys with immobiliser chip etc etc. It's not a way of stealing a car.

I looked at that and removed one then found it was held in by mastik and I couldn't pull the cable out far enough but on the plus side I now have two new LED units waiting to go in tomorrow once I have sorted the battery issue one way or another. Only other odd thing I've noticed is that the current battery has some sort of drainage tube but not sure that's an issue.

I can vouch for that :)

How can it be easier than opening the flap on the tow socket and wedging a couple of wires in?

I also think the previous mentioned way in was mechanical not with fobs. So technically it could tell you how to just gain entry to steal from inside the car or load on trailer.
So no I don’t consider it a comment to warrant calling carful members idiots.
A regular member/poster would probably have got the advice freely by PM.

Just for clarity, NAS spec vehicles of the L320/L319 era do not superlock by default, UK/ROW vehicles do.
There is a way of accessing the interior of the vehicle reasonably quickly - this is known to AA/RAC etc. and is used to access the vehicles without damage as in the OP's scenario. As it could be used to access the contents, release the park brake, park interlock & give access to the steering column lock, I'm not going to post it 'in the wild'. I've no doubt it's probably already out there, but I'm not going to repeat it here.

The tube is just a breather tube, all batteries have a breather some with a tube, some without.
