Dispatch 1.6 hdi Battery voltage.

[djmikeyboy]

Hello all, I've just joined this group in the hope that there are some electrical Guru's on here? I have a 2014 Dispatch 1.6 hdi that has just started throwing the battery light on after a few minutes of driving. On testing the battery I am getting a good average 14v at idle. The battery itself did not test great so I have replaced it and carried out the correct BSI reset procedure. The battery light is still coming on after a short while though. When I go into live data in the BSI unit it is showing the battery voltage at 10.5v while the tester attached to the actual battery is still showing a good 14v. As a side note the fuel gauge has also been acting a bit strange recently. So I am wondering if this could be a fault that the BSI unit or the dash could present? Something is telling porky pies and I'm hoping someone on here might have come across similar before? Many thanks in advance.

These new charging systems are ridiculously complicated from a fault finding point of view, if it starts and drives OK I would assume that it charging correctly but random faults would suggest the battery is going low on occasion. If the battery is passed its best it could be when you start the car, a lot of amps are drawn and it cause the voltage to drop below the tolerance of the electronics.

I cured the intermittent non functioning wipers problem on my C5 by fitting a new battery.

That was my initial thinking, hence why I put a new battery on. But the car thinks that the battery voltage is at 10.5v when it's actually at 14v. It is physically working correctly/charging etc but the car thinks there is a problem hence throwing the lamp on. I know that the BSI units can cause odd faults which was why I was wondering if anyone else had come across this specific one.

What battery did you install? The type of battery and current capacity are registered in the BSI and if you don't fit what the BSI is expecting then it will/might view the battery as still being at fault.

I did wonder about that too, but couldn't find any info on if that was required or how to do it. I am aware that some newer cars need to be told that they have had a new battery fitted. It should have been like for like (although from Varta OE to Exide) amperage wise. It was cross referenced by reg and by the original part number by the parts company. Both 640 A EN. So if you have any knowledge on how to reset the battery info with Lexis/PP (if it is indeed required) that would be a great help.

If you post your VIN in this thread (automasked by the forum software) someone may be able check to see what should be fitted. Hopefully this will be without cost but if we have to access the PSA parts service then, as we will then be charged by PSA for this service, we ask for a forum donation to offset this.

My gut feeling is that it should be an Enhanced Flooded Battery (EFB) rather than an Absorbent Glass Mat Battery (AGM) although that would work equally well. The AGM type are more expensive as they are fitted to vehicles with stop/start capability. Does your Dispatch have stop/start (or think it should do)?

How many miles has the vehicle done?

If the car is little used, give it a good go on a CTEK battery trickle charger or similar

It the only way I could keep the stop / start working on an XE

No it doesn't have stop start. I was asked this when purchasing the battery, and it was a direct cross reference by both reg and part number from the old battery which was the original Citroen one. So I am pretty confident that the battery is the correct one for the vehicle. Van has done just over 100,000. I have trawled the net for any info on initializing/coding a replacement battery, and whilst there are plenty of "how to " videos for VAG cars I have found none for Peugeot/Citroen. This is why I am suspecting a possible BSI fault itself? The fuel gauge misbehaving is also pointing me in this direction. I have made enquiries with a few ECU repair places to see if they have come across this one too. Will keep digging, maybe I'll get lucky and after a few drives it might calibrate itself or something, I won't hold my breath though.

What was the spec of the old battery?

[djmikeyboy]

I'll have a look tomorrow

I had a similar problem on my 2014 2l HDI Dispatch. Even after fitting a new battery it was still showing low voltage in diagbox. After a bit of searching I found out that you have to go into diagbox & tell it you have fitted a new battery & I think it asks what type. The battery I fitted was none of the options listed so I selected the closest match. Don't ask me where to find it in diagbox, it took me ages to find it & I just can't remember!

I'll have to check but I think I fitted a standard 096 lead acid battery.

[djmikeyboy]

Thank you, that's the answer that I was looking for. At least that confirms what I was suspecting that you do have to tell the car. I have diagbox so will have another play.

[Paul-R]

I did say that the type of battery is registered in the BSI and that it should match what is actually fitted to the car. If you replace the battery like for like and it was already correctly matched then you don't need to tell the BSI that a new battery of the same type has been fitted.

Of course somebody could have been in the BSI before and changed the type and you need to check/confirm this.
