Re: Battery removal

Take care disconnecting and reconnecting the battery, the Electronics don't like the battery being disconnected! Best to do a search for the correct procedure. From memory, this involves opening the driver's door and flipping the latch (so the ECU thinks it's closed) or opening any of the other doors or switching anything on, you then have to wait a few minutes for the ECU to go into sleep mode Bear in mind you won't be able to lock the doors with the key fob after the battery is disconnected

I seem to think the book says to remove the positive first, which seems to go against the general wisdom, its a quick release type so no spanners to short out. The space is very tight take care you don't put the leads and electronic components under any undue strain lifting the battery out. The leads should be put out of the way so they cant come into contact with the battery terminals you could wrap with dry rag

Reconnecting, again from memory flip the door latch reconnect leads with the key in the ignition but not switched on, turn the sidelights on, now turn the ignition on, and hold down the fob lock button for a few seconds. Remove the key try locking and unlocking the doors you should now be good to go!

Good luck.... Mick

For an "Oldboy" Mick you are doing a good job of keeping up.

i am so out of touch myself.  There was I thinking "just disconnect and whip it out" totally unaware of the potential electronic mayhem that might result.

Re: Battery removal

Thanks for info Mick,not sure if i want to remove battery to put on maintenance charge if its going to be an issue. Just wondered if there is a jump start connection point/s in the engine bay.Battery under drivers seat ,but maybe not a good idea to jump start it there?Any thoughts on jump starting if needed.I have a Noco GB 70   12v 2000A 56Wh Lithium jump starter.Supposed to be able to start 6.0 liter diesels.Used it last week to start my brothers mini cooper diesel ,no problem.Just a bit concerned with the Citroen Van.Any help appreciated,dont want to fry the ECU/BSI Cheers spritzer

Re: Battery removal

Jump starting is not a problem, according to the owner's handbook. I have fitted a second battery to my van via 2 Isolator switches. With this setup, you can then charge the second battery with the isolators open, disconnect the charger then close the isolators, this will bring the van battery voltage very close to the second battery. Driving with the batteries paralleled works fine, increases the time before the dreaded Eco-Mode battery saver mode kicks in

Hope this helps Mick

Re: Battery removal

Well I was disappointed finding out how complex "modern" auto electronics are becoming and knowing I would need to keep the battery charged, as I don't use the van regularly. Having a fear of BlackBox tech I researched the subject as best as I could, being retired I have time to indulge myself! https://dispatchexpertscudo.org.uk/foru … s/wink.png

You and me both...........

Several years ago I had cause to take a faulty air bag module into the VW specialist to ask what could be done with it...........
The car was a 2000 W reg Mk 4 golf and during being told options it was announced my car was Black (it was)...........
To be informed info came off the module as the car was "self aware and needed to know what colour it was".............

Another surprise came when a Renault Kangoo van that had gained enormous power and revs but would only start with a tow (Died shortly after with Dead ECU)
Needed injectors introducing to the ECU and a total of just over £2000 of which a significant amount was for introductions  time to ECU.................

At the time ...Needless to say at 130,000 miles and 5 or 6 plus years old it wasn't worth £2000.
And these being early versions of "self aware"

I've said before ..........."What happend to good Materials and craftmanship ....... Now it's how many Play Stations in a car = quality"
