Has anyone worked out how to open a 2018 Boxer passenger door when the battery is flat? I can't open the bonnet without opening the passenger door. Our continental cousins obviously don't have this problem. I know I shouldn't have let it get so flat but access problems led to this.

Can you not use a key in another door (i dont know if you have key locks in other doors) if you can get in cant you just pull the door lever from the inside

Why do you need to open the bonnet? The starter battery is under the floor between the seats you can open the drivers door with the key.

Access to the battery in storage was the problem my leads weren't long enough to reach from where the car was. The passenger door will not open if the battery is flat even from the inside, it all appears to be electrical!

Take the battery out, take it away and recharge it and fit back in again when charged would be the easy option. (y)

If it is not possible to use your car , Are you able to use your jump leads between the starter battery (under the cab floor) and the leisure battery , not to start the van , but to power the central locking electrics and be able to open the door to get to the bonnet release

open the drivers door with the key itself. that should unlock the dead locking on the passenger door.If it doesn't then you need additional jump leads to enable battery access

When I hear problems with various electrical malfunctions I am glad that we have very few electrical operated systems - steps, waterpump and Truma blown air fan. We can get in without steps and have spare water container with tap, so only Truma fan would be a problem, but we have a gas stove.

I am surprised that MH designers keep adding electrical-operated systems - drop-down beds, central locking, windscreen blinds, awnings, coffee machines etc. and all in a vehicle which has limited electrical capacity.

I assume you want to start to go straight away but if not then maybe just plug in the EHU lead and let the battery charge via the built in motorhome charger. OR get a stand alone charger and connect direct to the battery between the seats. (y)
Small charge may be enough to allow the central locking to work.. It may even operate when the charger is connected.

The problem the OP is having is with the base vehicle, not the MH conversion side. (y)

If the Peugot is like the Ducato the points to attach the jump leads are under the bonnet. To get in why not just open the Hab door or like others say the side doors, then jump start.

Not sure its a good idea to jump start unless you isolate the Hab electrics. I might be wrong but I was told its not a good idea as can also affect some sensitive ECU's like the airbags. Best to use a Booster or donor battery or charger to boost the battery first before attempting to Start. I've got a couple of BM2 battery monitors one on each Vehicle and Leisure battery. They aren't entirely accurate but does give you an idea of battery status and charge state via bluetooth on mobile phone.

If you attatch the (asuming) car to the van then keep engine running on car for 5 or 10 minutes it will give a bit of charge to get things going then try and jump start. Hab electrics will not be affected as you will have 12v isolated in van so nothing turned on.

I beleive the OP is in storage so not able to charge there, other option would be to take battery out then charge at home, can also see if needs a new one as if using a smart charger and battery is duff it will not charge so can then get a new one to replace easily.

Then OP should immediately get solar panel and something like a battery master fitted or like mine wired thru EBL so everything all kept topped up by solar panels.

he can't open the bonnet he said until passenger door is open as I assume the bonnet release requires door to be open?

When the door is closed it covers over the bonnet release.

Put the key in the drivers side door lock and turn to open the door that will work even if the cab battery is flat then you will be able to open the passenger side door from inside the cab. You do not need a fully charged battery to do that in fact you don't even need a battery to be connected, it's called manual operation.

No,not if they are deadlocked & battery is absolutely dead.
On my van I have only a drivers door lock.If battery is dead I can enter through drivers door but cannot open passenger door, side door or rear doors if they have been deadlocked until I have battery power.The same would apply with hab door. You can enter but cannot open deadlocked cab doors. The op's problem is as shown on the photo the passenger door needs to be opened to access the bonnet latch where the jump points are.

Probably not dead locked ours never is and didn't know you could but we are A class so maybe worth a try.

Our Ducato panel van would not start after a stop near Aviemore last yeat. Green Flag got us started and tested the battery and said it was fine. We got to a site in Aviemore then it would not start again. This went on a couple of times. In the end I had to insist they fitted a new battery, which they did and it has run OK ever since. I kept the old battery and tested the SG in each cell with a hydrometer. One cell ( the one covered by the clamp!) was way down.
Anyway some months later at MOT time it had been showing a fault on the gloplugs. The MOT man dismissed this as being a consequence of the battery having been at sometime flat. Apparently flat battery can throw up many faults. I guess he cleared the fault codes and its now OK again. Good mechanic.

What about rigging up the wires from a charger to the cigarette lighter socket?

I used to own a Porsche Boxster and had similar problems, if the battery went flat I could not pull bonnet release to access the battery which was under the bonnet (eventually got wise to this and if left in garage used to leave bonnet on safety catch only)
My work around first time happened was locate fuse for central locking and put power direct to the fuse from another battery, this allowed me to unlock the vehicle with the remote and open the bonnet.

i think most UK supplied ducatos do not have dead locks and the passenger door is unlocked with no battery in fact there is a utube video about the switch that has to be flicked in order to lock the door without power. of course op may have the switch flicked, but its normally off mine was.

Hm, not too sure about this, you could be right, but I seem to remember when I had a prob with BCM and battery was disconnected I could not open passenger door from inside car.

could be wrong.
