Battery Not Charging Fault

[Ceenine]

Actually, subject should read “battery unchanging fault”. My Adblue 2016 2.0 litre Ds4 is again misbehaving with this screen message “battery fault, visit your local auto electrician asap, do not pass go……” or words to that effect.

Diagbox informs that the fault is 1624 73 which is short for “arrange an appointment with your local bank loans manager”. I am losing about 0.2 volts each night after the car remaining in the garage, sulking.

Searching EBay, it is difficult finding a suitable replacement offered. Would you believe Walmart is offering a GR version, however I am inclined to view it as a scam unless Walmart have a store in Leeds or elsewhere in UK. I am leaning towards a used BPGA unit.


Would someone please suggest what might be available in the UK as there is nothing on offer in these PSA (Stellantis) backwoods.

Supplies protection and management unit: Central power switch positive (+CPC) relay status fault: Relay closed. So there would certainly seem to be an issue there...

Protection & Management Unit, part: 9665878080, £353.84.

Note these need configuring when replaced similarly to the BSI, and will need online access to do as it's a 2016 vehicle. So may be better to get the dealer to diagnose for certainty, fit and code as they are unlikely to code a second hand unit for insurance liability purposes if anything goes toes up with a non-dealer sourced electronics part.

Marc, the “online access” reference that you have included is very intriguing. Of the many videos I have watched on the subject of changing over the module, none refer to this requirement. In particular, a video relating to this process on a Peugeot 508 2017 model, which is quite prescriptive, makes no such online reference. Any chance of posting the PSA repair procedure like those I used to pay for from Service Citroen?

My car’s build date is December 2015 and it’s vin is NXAHWTFY574822.

Much thanks in anticipation

It depends on the vehicle as to the type of unit they have and whether it has to be configured or not. Many PSA vehicles do not have, but some vehicles like the DS4 / later C4, 508 etc do.

That's the issue with YouTube videos they are not vehicle -specific and what applies to one vehicle won't be relevant to another. It depends also on the engine and Engine Management System used, options etc. etc.

The issue of whether you can code this yourself may depend on the version of Diagbox you have. I believe that Diagbox update 8.16, available from 25/11/2015 may prevent telecoding - and whether this version has the capability to work with the ECU for your specific vehicle is questionable.

If the ECU is locked in secure mode requiring PSA log in and server access, it will be easier to get the dealer to code it subject to them agreeing to this. Otherwise you may gave to install the later Diagbox V9 from PSA, register, purchase diagnostic access tokens etc.

The first thing I suggest it to see if you have access to manual telecoding of the engine fusebox fist of all with your current version of Diagbox. I suggest you see if it will allow you to configure a setting without actually changing anything - it may not even allow you to get that far, which makes everything else pointless.

Thank you Marc, I will give that a try. I will report back for the benefit of those with a similar model and problem. Apparently this is a very common issue unfortunately, just like the dreaded Adblue tank.

So what is the expectation with donations for parts etc. is this an annual requirement. If so, my donation must be overdue.

Hi Don, donations for part number requests last up to 2 calendar years. So if joining 01/01/2022, you would benefit from all of 2022 and up to 31/12/2023, so 2 years, but if donating 31/12/2022 it would only cover you for 2023 effectively. Of course, members can donate to the Forum upkeep whenever they feel like it, and many often do!

Just bear in mind that donations as far as official parts are concerned, refer to parts and parts diagrams only. This does not cover technical documentation or wiring diagrams. We may only be able to provide those if a member already has them already and is willing to provide help.

Update on BPGA replacement. The unit arrived today. I contacted an Aussiefrogs member who in a past life worked in a PSA service centre for many years. He advised that the unit does not require coding by either Citroen or my Diagbox. The unit located on the negative terminal does however require coding to the BSI.

My vehicle’s built date is December 2015. His advice may be different for later built vehicles.

[GiveMeABreak]

He's out of date and incorrect Don. The Later C4 (B7) and DS4 have always required the engine fuse box to be configured on replacing. If you have changed the Battery Charge Status Unit on the battery negative terminal, then this too also needs configuring.

Items for configuration include:

Supply Options for Diesel / Petrol Engines, Heating / Ventilation, Compressor Type, Lighting / Signalling (multiple options), Alternator, Engine Type, Oil acquisition type, Oil Pressure Info, Actuator Diversity 1 & 2, Visibility / wiping options etc.

I have taken the plunge and fitted the new BPGA unit, sourced through Aliexpress costing all up AUD 350 including freight.. It was not very time consuming. I used my Diagbox which recognised the new unit instantly for date of manufacture, part code etc. My car was manufactured in December 2015 with the original part made in October 2015. The Chinese (?) made part is identical to the last detail (welds etc.) to the original.

The requirement to code apparently relates to later models thankfully. This facet of the process may be helpful to others experiencing this problem.

But has it cured your issues Don?????

Secondly as for configuration - the system will of course recognise it, but that does not mean it is configured. You may need to select the unit from the detected systems in Diagbox after a Global Test, then go into configuration, then manual configuration and check the values are set correctly for the car engine, heating / lighting etc. Otherwise you may find systems will start playing up.

The car is going well so far, eg lights, aircon., multimedia and most importantly the battery is maintains its charge. And that warning no longer appears neither at startup nor at various times along the journey.

We are travelling away for a few days in the C5 so I hope the car is still intact upon our return. As long as it doesn’t turn into a pumpkin.

Still waiting for the Adblue unit to cark it though!

Good news, at least you know what to look for if anything starts to go toes up. Have a good trip.
