New Battery in a Discovery 4

[Bundus]

When I collected my 2nd hand Disco I found it with the battery dead. Replacing it with a new Probe 100AH battery was a no brainer. Now I hear that the new battery has to be registered with the cars system. Is it necessary? How is it done, resp. can I do it? The next LR dealer is more than 100km away. Thanks for advice!

What year is the vehicle, is it 3.0l or 2.7l?

If it is 2.7l you will probably be fine,if it’s 3.0l yes it needs to be done.

Most battery suppliers can do it these days.

not so much registered. you just need to reset the 'smart' BMS so it knows it's charging a new battery as it's slowly adjusts it's charging cycle as the battery ages and capacity is reduced. you can do it with an IID tool or I think you can also do it just by shorting the car terminals. Disconnect the battery and bridge the +ve and -ve leads from the *CAR* (NOT THE BATTERY... OBVIOUSLY). this I believe will reset the BMS.

You cannot do anything but a “hard reset” (think reboot) by shorting the cables.

The BMS requires a tool

Will nanocom do this?
So this is for d3 & D4 or just d4?

Yes it can. Applies to 3.0s

In D4 2.7s you can set the battery type and size to optimise charging.

Wow [emoji15]
Can we have today’s comfort with yesteryear simplicity ?

So presumably GapTool can do the same for a 2.7? If so, care to point me in the right direction as my elderly brain does not recall anything from reading the ops manual (in almost one continuous session).

You know, I just took the old battery out and put the new one in.

I checked the Land Rover manual and there’s nothing about having to reset the battery management system.

Just because the manual doesn’t tell you, doesn’t mean the BMS doesn’t exist and doesn’t mean the ECU isn’t tracking your batteries ageing. You have a 2014 so it is a factor in the long life of your battery. Sure you don’t have to do it, but I’d suggest it will treat your battery as an aged battery and mistreat it.

Thanks, Scarry, it is a 3.0 Diesel.

You mean the simplicity of more often than not - flat batteries, busted alternators, failed electrics?

Lots of yesteryear simplicity came with the ability to fix. It was the irony of the constant fixing that seems to be lost on people now.

If it wasn’t for me doing checks every couple of weeks out of habit, I wouldn’t even need to know where the bonnet release was until the washer bottle needed filling.

Yet those older and simpler vehicles back 20-30 years ago had me spinning spanners, replacing points, plugs, leads, alternators, wiring in relays.....

There’s nothing in the OWNERS handbook.
And nothing about replacing a battery either [emoji41]

That’s in the WORKSHOP manual....

For a minute there I thought you were talking about D3 / D4's..... but then you didn't continue with things such as :
control arm bushes
split intake manifolds
failing coolant outlets
brake switch failures
failed door and tailgate actuators , switches , wiring
suspension faults
park brake faults including shoe material failing
blocked heater cores ( on cars with regular correct coolant changes )
egr faults
turbo related faults
failed and leaking oil level sensors
Instrument cluster faults
Spun crank bearings
.......................so I guess you weren't[bighmmm]

[Tombie]

Never had any of those [emoji1787]

Ok, Control arm bushes - mine copped a flogging offroad but they’re a service item.

A 2.7 making more than a TDV6 3.0 [emoji41]
