C4 grand Picasso battery

[Chrisbaz]

How can I check what battery my car should have from the factory. It’s a c4 grand Picasso 2016 1.6 diesel. The start stop has stopped working and if I switch the radio on with the engine off it goes off in about 2 mins and when I go to start it, it comes up on the screen charging modules. Just with these happening it’s leading me to believe it’s the battery please correct me if I’m wrong. I do have a smart battery charger I could try if it’s worth a go.

Thanks in advance

If you vehicle battery is 5 years old or over, it's probably due for a change. Charging it up won't help if it's losing charge pretty quickly - this is because the battery's capacity to hold a charge is diminished over time. So although you can charge it up, you are only charging a portion of the battery's original capacity.

This will impact on the energy saving mode (cutting in more quickly) and means the electronic systems may also start to become affected if they aren't getting the power they need.

With all the electric systems on the C4 Picasso and other modern cars, there is a lot to sustain.

On another matter of the touch screen. It is common for the modules to load once the ignition / vehicle engine is started. The various modules start to load up and can take a few moments - especially if you have switched the ignition off and then on again. This is not a fault.

Thanks givemeabreak for the quick answer now you mention it I have noticed a few things act weird Iile the screen randomly going off.
So I just need to find out what battery I need to get and do they need coding when replaced. My last car bmw when I changed the battery it had to be coded in.

Thanks again

It's not 'coding' as such, but there is a Battery Charge Status Unit on the vehicle that monitors the condition of the main battery's heath, temperature etc., and advises the BSI when to put the car into energy management mode.

This unit will already have had the relevant parameters configured, such as the battery type and level (as in Citroen's levels - L1, L2, L3 etc.) the levels equate to the capacity and output, so I would advise on replacing with the recommended capacity. Pop your VIN up if you want to know the correct capacity for your vehicle.

ok then thats good its all set. my vin is VF7**************[VIN obfuscated, can be read by forum staff] thankyou very much for this really appreciate it. when i looked there was few different battery types on euro for my reg id rather get the right one

You want a 096 AGM type battery, I would recommend a Yuasa YBX9096.
Whatever battery you choose needs to be AGM & at least 760 CCA.

PS your vehicle has an outstanding (non safety) quality update needed, contact your Citroen dealer about this.

[Chrisbaz]

Thankyou for that i shall have a look at the yuasa battery.

What is a quality update? is that to do with the software?

Thanks again

[GiveMeABreak]

No, it can be a variety of issues from electrical, mechanical or software related. Book it in and advise them of your VIN. It won't cost you anything.

[Chrisbaz]

Thankyou i will give them a ring looked online and saw 3 recalls for my vin including timing belt one thankyou so much for your help with it all much appreciated

[wheeler]

Why the sad face? looks like you may be getting a free timing belt replacement

[Chrisbaz]

I suppose that is a plus if they do I have been hearing a funny noise like a tensioner whirring when going slow but relevant to engine sound. It says the fault is the timing belt degrades blocking the vacuum pump so both are replaced on the recall.

Could you possibly tell me what battery I should purchase from my vin number?
