FLAT BATTERY in a week 2003 4.4L Vogue

[Shirley]

Hi Fellas,

The battery gremlin strikes again.. From the P38 with a BECM that had insomnia to an L322 with a similar issue!
Is it possible that I am missing something simple?
I thought it might just have been a old battery so I bought a new one. A monster 880 CCA Calcium Job that cost a fortune and made sure it was fully charged on the smart charger, did a battery test and got the same deal after a week in the shed. Flat as a F*rt in a week.
Checked the charge voltage from the alternator at 14.1VDC, No errors on the dash readout, no errors codes in the computer so I'm not game to lock the thing...
Has anyone and thoughts on this problem that would have been contagious from older P38 to the L322?
Maybe I'm not holding my mouth right or something??

Help if it is at all possible,
Shirley - Wyee Central Coast NSW.

Shirley
Try checking these;

Sat=Nav - CD continually trying to load

Headlight Wipers - if not working, power is on continually

Rear Cargo area Amp - moisture around connectors

Final Stage Resistor - check fuses for power

I hope this helps

I would never leave mine for more than a week not running or the battery would go flat. I'd either disconnect the battery or start the car and take it for a run as ours didn't do much for the last 12 months we owned it - and I killed a battery in at in that time. It's one of the flaws of its design IMO, but if you're aware of it, you can stay on top of it.

A bit of a PITA if you're using it infrequently like we did, but I think they were made to be driven.

Maybe you have a fault like previously described or maybe you will just need to drive it more. :)

Mines a later L322, but I parked it for 3 weeks as we were away OS.

Returned and it started like I drove it yesterday. Even air suspension was fully inflated.

There has been some recalls on some LR products for the instrument binnacle causing battery drain. The computers don't always go completely to sleep, so maybe look at that.

Hi Laurie,

I hear you mate, and it seems that someone else has been investigating that area before I bought it.
Will section off all the modules in the back and see if anything is staying alive when the ignition is off...

Many thanks,
Shirley...

How are you getting on Shirlewy, I joined the dead battery brigade today.Bought a 880CCA Yuasa to replace the 800CCA existing battery, Soi $299 poorer:(

Hi Shirley and your flat battery is commonplace in a TD6 L322.

They have a fair bit of power being draw from the battery, long after the key is removed.

I was averaging 6,000Kms a month in my TD6 L322, yet on the rare occasions that I left it unused for more than a week, I would be lucky to be able to start the motor.

My TDV8 L322 could site unused for a much longer time and still start OK.

If you can, try using a battery charger when ever your RR is not likely to be used for a few days.

You don'y need a high current charger, anything from 2 amps on will do the job.

Charging your battery regularly will not only keep your battery in a good sate of charged, but will greatly help to extend your battery's life span.

Drive safe , Is it also a common thing for a V8 as Shirley's is a V8 not TD6

Hi Roverlord and yes, the early versions of the L322 are all renown for large consumption of battery power when the ignition is off.

I can remember seeing battery chargers suffer under the Range Rovers on display at the different dealerships.

This is where you need to come in and design something that turns off everything except the alarm /immobiliser system.;)

I know there was definitely some mods done to my car early on when I didn't own it by the dealer.
It had something to do with shedding power.
I think it was some item right near the battery.
Mines a MY10 TDV8.
Since I've owned it I've also updated all the firmware in the different ECUs with my iid tool with their help.
I just had to pay them money but it wasn't much.
I don't seem to get many errors in my car anymore.
Only the occasional communication error to the park brake module.
And a communication error to the drivers seat heater.
But they don't seem to affect anything and can be easily cleared.
So double check there's no recalls or mods the dealer needs to do.
And check if any built in computers need updates.
This can be done by the dealer or the guys at iid tool.

[rar110]

Blade how much was the IID update?

[Blade74]

I just sent you a PM. It wasn't too expensive but I may have been a test case. There was about 12 firmwares for ECUs in mine that were old. You have to be very careful and read all instructions and make sure your battery is fully charged. I'm sure the dealer could do it too but may charge more.

[Blade74]

I'm not sure if the gap iid tool supports 2003 models? Where do you live Shirley?
Graeme Cooper automotive may be able to help.

[Blade74]

Ok so yes it does support your car.

Range Rover L322 2002-12
Just not sure if they would do updates for it though???

[Blade74]

Also Shirley log into topix and enter your cars Vin number.
Double check there's no outstanding recalls.
My later model had a recal Q159 for this same type of problem.

[Homestar]

Ok so yes it does support your car.

They have done several updates in the last few years for them. Well worth the investment in one.

The Gap does support the early L322s, but you can't update the firmware for the ECUs on the early models. I asked GAP about it and the answer is NO

I can remember seeing battery chargers stuffed under the Range Rovers on display at the different dealerships.

Could be a new line for you to make Drive safe? A discrete roof mounted slim line Solar trickle charger maybe something low profile that mounts at the rear near the roof line stop light? Probably be a market for it.:)
