BPGA replacement on 308SW
Hi all,
My 308SW (2017) has developed the common battery/charging/all systems fault that seems to be due to a failing relay in the BPGA (part 9675350280).
I've watched a video that shows that replacement is simply a straight swap over.
However, two potential suppliers of the (expensive) part tell me that it has to be programmed and I'll need to take the vehicle to an authorised service centre or dealer.
Can anyone kindly explain what needs to be done and whether or not it is a DIY job if I get, for example, an OBD scanner etc.
Many thanks

Re: BPGA replacement on 308SW
Please don't create multiple posts for the same issue - I've deleted your other post after I had answered it and then saw that you created this thread. It causes duplication of answers.
In anwer to the other deleted post:
But as I've said, I would need to check from your VIN, as not all these need configuring and that is why there is no clear guidance and contradictory advice - that's YouTube and sellers that don't always know what they are on about.
In anwer to the other deleted post:
OBD scanners don't have the capability to do any programming or configuration in any case. You would need a professional dealer-level diagnostic kit to do undertake anything like that, should it be required.@dram773: My answer above was specific to that member's vehicle.
The advice will differ depending on the exact model and electronic architecture of the specific vehicle. So in your case, I will need your VIN to confirm. Please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff.

Re: BPGA replacement on 308SW
Ok, so confirmed that there is no coding required for this unit on your vehicle.
The supplies protection and management unit cuts the power supply to make the vehicle safe in the event of a short-circuit.
However if doing this replacement yourself, you do need to be thoroughly careful to ensure that you mark ALL the cable connections correctly to the exact locations / Fuse positions on the unit, as the fuses will differ from vehicle to vehicle depending on fitted equipment and options, so will not be the same from vehicle to vehicle. We won't be able to advise if you get these wrong on reconnection. So I'd recommend good quality labels and plenty of photos as you go along to document the removal.
Before removing, carefully clean the area of the old unit, so you can clearly see the identification markings first.
It goes without saying to follow the BSI Reset / Battery Disconnect / Reconnect Procedure before disconnecting anything.

Re: BPGA replacement on 308SW
Hi Marc,
Happy long weekend.
I have a similar problem to the OP. The symptoms for my car are:
- The little amber light next to gear stick on P doesn’t switch off after door is locked, very occasionally it switches off but then the problem returns.
- The light drained my battery to ~8V after 5 days of not driving. I had to physically open the door with the key. I pulse charged it to full then took it to Halfords to confirm battery health is at 70%.
- Dashboard light are ‘Electrical circuit fault: Have the vehicle repaired’ and a permanent SERVICE light.
- Sometimes dashboard show car going into economy mode before switch on.
- Alternator charges at 14.5V
I want to attempt to replace the BPGA (part no. 9675350380) by myself. Would you be able to check whether my car requires re-programming after replacing BPGA? Cheers.

Re: BPGA replacement on 308SW
UPDATE
I bought a replacement unit through AliExpress, approx £135 including postage and customs fees and arrived well packed in just over a week.
Finally found time to fit it yesterday, between showers. Photos of layout and wiring, plus all cables/wires labelled with tie-on tags.
Layout on my 308SW completely different from YouTube videos of 508, so took extra time to work out how to remove the BGPA from vehicle - easiest is to remove the mounting bracket and then remove screws attaching BGPA to bracket. After removing the top and bottom covers, it is simply a matter of transferring the wires over to the new unit together with any fuses that are missing on the new unit (2 in my case - this is because the same part is used on several Peugeot and Citroen vehicles).
Followed the battery reconnect / BSI procedure (see Marc's reply above) et viola! No service/warning lights and vehicle started fine.
Just had to reset the time/date and passenger window anti-trap, which is normal when battery disconnected.
So hoping problems now fixed but need to monitor over the next few days and weeks, as the original problem was intermittent until it refused to start at all.
Total cost about £135, compared to garage quote of £350 parts plus estimated £620 labour = £970 plus VAT.
Good luck all, and thanks again Marc for your kind help.

Re: BPGA replacement on 308SW
Hi Oliver, sorry I must of missed this post, so haven't been ignoring you. No, there is non programming required for the BGPA unit replacement, just be careful to photograph the position of all the fuses and wires before taking them off, as there is not guide to replacing them, as they can be different for each vehicle depending on fitted equipment.Olch wrote: 24 May 2024, 20:10 Hi Marc,

Re: BPGA replacement on 308SW
Hi Marc,
I also have a problem with my BPGA unit; the auto electrician who diagnosed it has advised me to go to the Peugeot main Dealer to have the work done.
The main issue with the Peugeot dealer is the cost and my previous poor experiences with the same dealer for warranty electrical faults.
I found the part online (part code 96753502820) sold by Neo Bros based in London for £237.50, https://www.neobrothers.co.uk/car-parts ... 9675350280. I don't fancy trying Aliexpress, even though this would save a lot.
Given the replacement of the BPGA sounds straightforward, if done with care as you have outlined in your posts, I would like to replace it myself.
The real decider though is whether the replacement will need to be coded to the vehicle, mine is a Peugeot 308 SW Mk 2 1.6 120 HDi Diesel, if I sent you the VIN would you be kind enough to check whether my car requires re-programming after replacing BPGA please?
Thanks, Tom

Hi Tom
Let me have your VIN and I will see if it needs configuring or not. Some do and some don't - depends on the model. Please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff.

Re: BPGA replacement on 308SW
Hi Tom,
If Marc can confirm that you don't need to reconfigure, I'd say replacing yourself is quite straightforward so long as you follow Marc's excellent guide on disconnection and reconnection of the battery. If you want a quick-and-dirty check of the BPGA, you can use a thick cable to temporarily bypass the relay by connecting the two main contact posts - accessed by two plastic sliding panels. If you do replace, I suggest taking plenty of photos and labelling all the wires before detaching them. You may have to transfer over fuses from your old unit and, similarly, you may find redundant fuses on the new unit - just make sure the finished item is a replica of your original and I don't think you'll have any problems. Good luck!

Thanks dram773,
I'll send Marc my VIN no. and keep my fingers crossed. I have read and will follow Marc's advice on disconnection and reconnection of the battery. Thanks also for the advice on the diagnosis. Would this relay bypass mask the fault giving certainty on its root cause; the symptom is a "Electrical circuit system: Have the vehicle repaired" warning on the touch screen"? I also have the problem of the battery running flat in less than a week but I'm pretty sure the battery health is good.

Re: BPGA replacement on 308SW
Hi Tom,
In my (rather limited) experience, the common fault with the BPGA is that the relay develops an intermittent or permanent fault. In which case, bypassing it by connecting the two main terminals will confirm the fault. For example, if the vehicle becomes 'locked out' and prevents the engine from turning, this will enable you to start it. The electrical warnings are typical of a failing BPGA but, of course, there are other possible causes. If the bypass trick doesn't resolve the issues I would suggest getting diagnostics to see what fault codes come up before splashing out on replacement parts.
