Replacing Agm Battery Ehdi 1.6 C3 2014

[Bluebird16]

Hi Everyone

Can anyone help Do I need any special tools I.e Diagnostics to change this type of battery myself

The Start/ Stop system works fine for a few days but since Xmas has had the hump and refused to work. Alternator charging at 14.7v ,,,,,I’ve turned of all unnecessary kit off fan/aircon/radio but that doesn’t help

The car is 3 years old But it was parked up for 12/18 Months,probably Waiting for me to come along. I’m a Driving Instructor returns brilliant MPG 55 + easy. ,, loverly engine as with the others very forgiving to pupils

My old Xsara Picasso had a procedure of opening drivers window and waiting for system to shut itself down Before changing battery

 

I’ve tried to find info But got Baulked when I saw a site say basically you have to tell the onboard computer that you are changing the AGM battery thru diagnostic tools

My 3rd C3 downside No Cup holders glove box Door miles too wide as a Filofax in door won’t let the glove box , shame

Many Thanks in advance

For your help

I could not find any need to do a diagnostic in the Citroen service box procedures when the battery is replaced. You can also look in your handbook but usual things are to reset the clock/date. If you need to replace the large capacitor inside the left front wing which starts the engine then that needs a tool to discharge it before removal and then a diagnostic to initialise it after replacement.

 

When disconnecting/connecting a battery I have found the following from the Common Problems topic works well without causing any odd electrical problems:

20. Odd electrical problems caused by wrong battery disconnection procedure.

If you need to disconnect the battery and not do a BSI reset procedure, I have found the following has not given me any problems on a 2004 and 2007 C5 and a 2003 C3:

- remove the ignition key from the car

- open the bonnet

- wait a few minutes for the BSI to shut down

- disconnect the battery negative terminal

 

When reconnecting

- ignition key out of the car

- reconnect the battery

- wait a few minutes

- insert the key in the ignition and wait a minute

- turn the key to the first position and wait a minute

- turn the key so the dash lights come on and wait a minute

- start the engine

- take the windows down and up to reset the anti pinch

- reset the clock (and radio on the C3).

 

If you do not want to open the door after connecting the battery, then the driver's window could be wound down before disconnecting the battery but I have never done this and not had any problems, or you could leave the door open and close its lock around a screwdriver which lets the car think the door is closed whilst the battery is changed. You have probably already found the correct batteries for stop/start cars cost a lot more than ones for cars without this. The alternators which can start the car can also cost a lot if they need replacing. I think the only benefit in stop/start is to reduce pollution in towns since there is no financial advantage taking in to account the high maintenance costs of early battery and alternator failures.

Hi Paul

Thanks for your reply

Have replaced battery ( AGM ) to correct spec

I did as you suggested it was Very similar when I had a Xsara Picasso.

 

Start Stop did not work for a week But yesterday Tuesday it stopped and started .. Been out and about today and seems to be working ok

My last resort was going to be when my service is due in about another 800 Miles and get the garage to diagnose it ,But Hey Ho Away We Go

 

MANY THANKS FOR YOUR INPUT
