It looks like you have lost communication with the CAN bus. I have attached two files for the BSI (the fuse box you have been working on). The image of the fusebox is not that good in the main doc (P508_fusebox) so I added a better copy of the image P508_fusebox_1).

I think your arrow was pointing at fuse 34. This and many other fuses in the BSI gets its power from the battery protection unit (BPGA - a seperate fusebox on top of the battery). My wiring diagrams only covers cars up to late 2013 and they show fuse 2 as being the supply to the BSI but it may have changed in the 2015 version so If fuse 2 is OK you should check all the other fuses in the BPGA.

I have attached the details I have in Peugeot Servicebox for the BPGA and it looks like it is the unit you have. Fuses 1, 2, 7, 8, 14, 21, 5, 20, 15, 5 and 19 are connected directly to the battery so always have power. The remaining fuses are controlled by a relay. This relay turns on as soon as you unlock the car and stays on for several minutes after you finish using the car.

Note: On most cars you can tell if the BPGA relay is on when the mirrors unfold.

The PBGA is a safety device. I understand that one of its function is to turn the power off in a crash.

The interesting thing is that the BSI (Built-in System Interface) is powered by fuses 2 and 4. Fuse 2 always has power whereas fuse 4 is controlled by the relay.

What I suggest is that you unlock the car and open the door. Then measure the voltage at both sides of fuses 2 and 4. The fact that BSI appears to be turning off after you stop the car it is likely there is only power reaching the BSI from fuse 4 only. I can see from your photo that the fuse numbers are punched into the metal rails.

There is a large black connector on the BSI which I have ringed in red this is where fuse 2 and 4 connect to the BSI. If both fuses are okay in the BPGA I would check the voltage at both pins on the connector. Note if the BSI is disconnected fuse 4 will probably be switched off.

Edit
I have attached a wiring diagram of a 508 BSI. I don't know your engine details so it may not be the exact unit for your car but should be near enough. The things I noticed from your diagnostics are:
Tyre deflation not working - fuse 5
Head up display not working- fuse 34
Airbag ECU not working fuse 25
Power to BSM fuse 23

Fuses 34, 25 and 23 are controlled by relay R2. Relay R2 and fuse 5 all get their power from the permanent connection (pin 2) at the large black two pin plug (2V NR) which is powered by fuse 2 in the BPGA. Hence my conclusion is that the power is not reaching the BSI from the BPGA. This could be due to fuse 2 in the BPGA, a bad connection in the plug 2V NR or a bad solder joint in the BSI. One possibility is that when you worked on the BSI you dislodged a poor connection inside the BSI (e.g. dry solder joint). Once you get the BSI inside out of the cold you could check the continuity between pin 2 of the large 2 pin plug (2V NR) and fuse 2 or 3 (needs to be a fuse not controlled by a relay).

It is starting to sound like there isn't a hardware fault.

I have just reread your fault report and I think you may have corrupted the BSI. The BSI can be a bit temperamental. There are four Electronic Control Units (ECUs) which are not configured. These include:
BSM -2010 (engine fuse box)
Climate Control (air-conditioning)
Drivers door module
Voltage maintaining device (associated with stop start)
The most important of these is the BSM because it is an extension of the BSI and control several things.

Have you tried to reboot the BSI? If not I would try disconnecting and reconnecting the battery. I have attached the recommended procedure.

Did you do the diagnostic test yourself or was it done by a dealer?

I have also attached the wiring diagram for the brake lights. As far as I can tell the power to fuse 12 is always there so it's the BSI that controls the brake lights. My guess is that if you remove fuse 12 the brake lights will still be on when driving.

Wouldn’t be surprised if the BSI have been corrupted as I have unplugged the battery allot of times. I’ll do a new diagnostic (have a lexia device with diagbox) and see if I can get some data from the devices
I think you can just go into Diagbox BSI programming mode and reset the ECU parameters. I think the important one is the BSM so it would worth looking at that.

Tried to click "action" on some of the Configurations but it wouldnt let me. Could be I either need to take it to my dealer or purchase a token for Diagbox.
Also, here is another scan with even more faultcodes than before, wihu... (Faulty hands-free doorlocks is because its just broken and needs to be replaced)
I think you should be able to do this manually. I think the best thing is to concentrate on the BSM. I am not familiar with the screen you are showing they look like the a list of setting rather than the usual diagbox settings option screen. However, I think it is showing the choice of option where an option hasn't been set. For example relay 1 setting - I think it doesn't know if the car is petrol or diesel. It might be worth reading this it gives instructions for configuring the BSM on a 508 : https://frenchcarforum.co.uk/forum/viewtopic.php?t=49329&start=15

EDIT
Are you using Diagbox V9 by any chance is so you may be right about needing a token. It might be worth doing a seperate install of V7. It should be okay for your car and doesn't need to link to the PSA servers. Windy1630 has configured it for a virtual machine and if you want it he has also included Servicebox which is where I get my wiring diagrams. See Windy's post here Service Box no longer free?

Will give it a try. Thanks!
I think I just worked out what the two sets of settings mean. The first are the actual configurations and the final set are the options available. All configurations appear to be set except for the compressor with clutch in Heating/ventilation (air-conditioning). It needs to know if the car has stop start.

Please, does anyone know where I can get BSI/ECU control unit for my Peugeot Partner 2017? New or Used one.
Thanks
I suggest you start a new thread in the Vans section of the forum.

You may find something on eBay but you need to make sure the ECU kit (ECU, BSI ignition switch and key) is an exact match to your existing unit. A dealer is the only place I know to get new ECU and BSI but they will need programming.

I just compared you new and old fault logs and several faults have gone. The tyre inflation ECU is still not communicating so I though I would look at its wiring diagram -see attachment. The green lines to the inflation ECU (7600) are the main CAN bus. There will be several other ECUs on that bus but I haven't identified anything else missing on that bus. Hence, perhaps the tyre inflation ECU is not getting power. I wonder if the Shunt fuse (labeled SH) is plugged in properly. It should be in the customer position (as per your BSI photo).

Of course the fuse for Tire Inflation is all the way up here and almost impossible to reach, but I`ll give it a try. I was also wondering about the Shunt fuse yesterday and checked the position, it is on the client position.
Sometimes when there is a faulty ECU on the CAN bus is can cause a problem on the whole bus. Rather than trying to access the fuse it might be easier to unplug the ECU (7600). It appears to be at the back of the car see attachment.

It might be worth taking the shunt out to make sure it has continuity and also try moving it to the other position and see what happens. The pre-delivery position should only disable a few items while the ignition is off.

I looked a bit more closely at the shunt and most if not all your faults seemed to be linked to the shunt. I also note that it's very close to one of the fuses you worked on. My guess is although it's in the correct position I suspect it's not making proper contact. If it's not making proper contact the following will not work:
Deflation detection ECU
Some switches under the steering wheel- communication unit
Some item associated with the other passenger compartment fuse box
Telematic ECU if fitted
Alarm if fitted
Brake light switch (this would explain why the brake lights are on all the time)
ESP ECU if fitted

I would pull the shunt out and have a look at it to see if it has been hot. If you put it in the pre-delivery position everything should still work when the ignition is on.

Tried to check it the other day with a fuse tester and it was giving me the green light. Can try to put it in the other position.
Thanks again Ian for your time! Really appreciate it!
The problem has me quite intrigued.

It will be interested know what happens if you move the shunt because most of the faulty ECUs seem to get their power via the shunt. If I am right removing the shunt completely should make no difference to the faults.

I was thinking the same the other day and was checking if it was okey with a fuse tester. But I’ll give it another try and maybe see with ny voltmeter when the car is off
I think the shunt itself should be okay. Some people call it a fuse but I think it's just a link. If there is a problem with the shunt it's more likely to be the contacts it plugs into in the BSI or a dry solder joint in the BSI.

I am not sure how you managed to lock yourself out. I had assumed you would have had to open the car to move the shunt. However, that was useful because it tells us the fuses associated with the shunt are getting power.

There is one last thing worth doing - try removing fuse 12. If the brake lights still stay on it will confirm that there is a problem with the BSI. The BSI controls the brake lights. The switch only provides a signal to the BSI.

EDIT
I see fuse 12 is difficult to reach so you could try taking the shunt out instead.

I think two of your problems are quite important:
(i) Brake lights
(ii) Oil pressure regulator - this may be a real fault. There are very few details on your engine (DV6FC) in my old installed version of PSA ServiceBox but I can see that there is more information on the current online version of ServiceBox (Service Box ) and there is a procedure to change the oil pressure solenoid. The other 1.6HDi (DV6C) only shows a oil pressure sensor/switch.

If you want to look into this anyone can register for servicebox but they now charge to access any documents.
