Hi Ian M Davis,

Yes, I have fold-in mirrors, and working fine when I unlock the car. I have a STOP-STAR system and is NOT working for a while just I can see ECO light blinks.

So what I can test or check??, where is this module or Unit "the centralised voltage maintaining system"??, The alternator gives 14.4v when the engine is on. The battery level this morning before the contact engine was 12.3V, after the contact 11.9V. so maybe is battery issues????


Please see this forum for similar faults they change the Battery protection unit cause the problem Electrical Service System Fault | Peugeot Forums

Many Thanks, Ian.

You could be right If the charge voltage is 14.4V and the battery is not holding charge. It could be as simple as a bad battery. The car has load shedding and I think the first thing it disables is the stop-start.

I read though your link and it appears the person was unsure what was changed "Well I'm pleased to say the battery is fine...it's the Battery Protection Unit (..or they may have referred to it as a Voltage Protection Unit?)". I suspect the fault was with the "centralised voltage maintaining system".

Can you check if you have a reverse alternator? Reverse alternators are slightly larger. The connection to the battery is the normal single terminal but instead of a 2 pin control plug it will have 5 pin plug. I tried to find a centralised voltage maintaining system on the Internet and this is what I found: Start/Stop computer Peugeot 3008 - 9805721280 9HD CONTINEN. Unfortunately, Service box doesn't show the location.

Hi all

first post but after reading all 61 messages in this forum I sadly need to add another situation to the mix. my 308 Gt line (19) was sat on the drive for a few days whilst I used my partners car for work. I went to move it and was faced with the same fault indication as you all 'battery charge fault - stop the vehicle' so I did just that and turned the engine off, I put a meter across the battery thinking it was on the limit but it returned 12.4vdc so started the car again and checked with the engine running this provided a 14.3vdc result. This is where my fault differs slightly from those before me, I've lost no functionality prior to and after the fault showed like lights or mirrors etc named in here, the car will also start first time every time.

After reading the posts in here I checked the neg side to the engine and returned 0.1 ohms, no obvious signs of corrosion either. I have however spotted one thing to the right of the battery as shown in the images that will hopefully be attached to this post that the bottom left nut is missing from what I gathered at the time is a fuse! the component itself is showing open circuit whereas the same ones in the box are showing 0.1 ohms. I dont know whats on the other side of the fuse but has this box got anything to do with the fault (only looked in there as the pos went that way). I've ordered a replacement fuse which should arrive by friday. I will update if its fixed it but ultimately this post is looking for suggestions if it doesn't and hopefully provides information to others if it does.

hanks in advance

I will have a closer look at your problem later today (my time) but my first observation is I don't think the missing nut is an issue. It looks like that fuse is not used on your car. The same fuse box will be used on multiple versions of the 308 and possibly other cars in the PSA range so it is common for some fuses not to be used.

If the 0.1 Ohm was real it would cause a problem. For example if you were drawing 30Amp you would get a 3 Volt drop. It is very difficult to measure low resistances accurately. It is better to turn the ignition on which will draw some current. Then you can measure the voltage drop.

Servicebox shows two types of electrical systems used of the 308 T9"Full Electrical Architecture" and "ECO Electrical Architecture". Based on your photo your car appears to have a version of the "ECO Electrical Architecture". The other version has a BPGA mounted on the battery and the connection to the fusebox passes through the BPGA. In your case the fuse box connects directly to the battery. The BPGA used on some 308 T9's if faulty the mirrors will not to deploy and the engine will not start. I think your car has a reversible alternator as part of the stop start system. There is a "centralised voltage maintaining system" that controls the reversible alternator. I suspect this component or another component associated with it (e.g. the accumulator) is causing your issue. This may be what the unit looks like Start/Stop computer Peugeot 3008 - 9805721280 9HD CONTINEN This component connects to an energy accumulator and I understand these sometimes give a problem see: Energy Accumulator Fault P1A9C

Hi Cott,
I think you should measure the voltage on the battery at least 2 hours after the engine OFF or after overnight, if the voltage is under 12.4V you should replace the battery.


Thanks

Quick update, fuse changed and new nut fitted as suspected by Ian this had 0 effect, new battery fitted and fault initially still there then went away 30 seconds after starting only to return 5 minutes later. Throughout car has remained stationary.

I have attached two versions stop-start system wiring for the 308 T9. The Eco version appears to fit your car. The other version has a BPGA (block 1032). The BPGA sits in front of the battery on the T9 and I can't see one in your photos.

I am fairly sure you car will have a reserable alternator so blocks 1012 (centralised voltage maintaining system) and 1026 (energy accumulator) are important. These two components usually sit at the top of the left wing. You need to remove the wing lining above the left wheel to get to them. The accumulator has been known to give issues.

This link may help you to understand the reversible alternator system: New Peugeot 308 features e-HDi micro-hybrid technology; CO2 emissions start from 98 g/km

This is an example of the voltage maintaining unit and accumulator: Start/Stop computer Peugeot Partner/Ranch 1.6 HDI 90 - 9802096780 9H06

Hi Ian

Thank you for yet another comprehensive reply with diagrams, the car has decided to sort itself out, I suspect the battery change did the trick. Was able to use it as normal later in the day and this morning with no issues at all.

Hopefully my errors will help someone else and once again thank you all for the replies and help.

Hi all. I got 3008 18plate with 34k. I have electric circuit error for 2 weeks now, took it to mechanic he checked the battery and said it's fine, connected and checked for error codes, it showed 14 of them, he didnt told what they were He said he will contact hes friend at Peugeot and get back to me. Tody my car would not start and it said battery charge fault. When I unlock the car my mirrors did not unfold. So now I'm thinking do I have same problem as you guys have or does this have something to do with the first error. Any help much appreciated Nick

That sounds like the exact problems I had on my car replacing the BPGA did fix it for me. I got mine off AliExpress but there are a few different types.

Cool thanks. I called rac for them to double check and I booked it in to the main dealership as I still got warranty till may.
Does anyone know if I have to pay for it if I got extended warranty??

Update. Waited 7hrs for RAC. But he fixed it, seems all good now.
He said it was something to do with bsm? Or something like that.
But I'm just one happy man now.
He said if something happens like this again. Remove the wire from battery wait for 5min, put it back on, press and hold lock button on the key. Unlock it if the mirrors come out it's all good if not repeat something again.
So maybe this will help someone else.
