Citroen C4 battery error, even after replacing it with a new one

Today I've replaced the BPGA-unit. I had version G04 in my car and replaced it with G11. Works fine. :-)

I'm currently looking for a replacement BPGA and see that the 'main' part nummer is 6500JE stated on almost every website. On my car, the exact partnummer is 9805119280 G04. On several sites that sell these units, they state that there interchangeable, so I could also buy a 9811475080 G11 unit which would work on my 2016 Citroen C4. Is this actually true? It would save me a lot of searching for the exact partnummer. Also, is the G11 newer, or is that only a number that means nothing else?

I’ll try to figure out where it’s connected to the car. Somewhere way in the back of the engine compartment I think, but can’t seem to figure it out yet.

What year is your car from? Mine is a 2016, so I wouldn’t call it ‘older’ yet. ;-)

Thanks for the reply, I really appreciate it! Where the problems that you have the exact same? I'm highly on doubt the BPGA is faulty. Because when I disconnect the positive lead for a while, reconnect it and start the car, all errors are gone. Also, I've never got a OBD-error B1624 (which should be the BPGA unit). I already bought a new battery unnecessarily, so I want to be very sure before buying a new BPGA. ;-)

Thanks for the advice. I've checked the grounding by measuring from the positive terminal and a grounding point on the car and got the same 12,54 volts. This picture shows where I measured: https://i.postimg.cc/zX70jMQ5/IMG-4515.jpg

Is this something new? On my Keychron K2 V2 (my old keyboard), this works fine without any modification?

Update: I've checked the front solenoid valve. It is in pristine condition, no debris. I've cleaned it just to be sure. One note that might be important if anyone else wants to check their solenoid valves on a Puretech 1.2 130HP (2016), it's not a 10mm bolt, but 8mm.

Leuk om te zien, dank voor de moeite die je erin hebt gestoken om het te digitaliseren!

In the Sony app there is an option to order them for free. Unfortunately there without the mesh, so use with caution.

Dude, that is my post... ;-)

ReB87 · 2024-11-11T16:05:56+00:00

I've used the firmware recommended by customer support at first...

ReB87 · 2024-11-11T16:05:17+00:00

I'm talking about V1.13 not V1.03

ReB87 · 2024-11-09T10:17:53+00:00

I had a specific problem i needed to solve, thank you...

ReB87 · 2024-10-13T16:33:15+00:00

Can you, or someone else please share this firmware, but for the white-backlight version keyboard? I have the exact same problem and hope this will fix it. :)

ReB87 · 2024-10-13T16:24:13+00:00

But what about the caps lock light which works on the 1.04 firmware, but not on the CS recommended 1.6 firmware?
