does anyone have the reference number of this TSB or even better can anyone send me a copy if they have access to it ?

looks like fitting a new battery hasnt fixed the problem. ...Still getting Low voltage message despite the new battery and good state of charge.

(the old battery was also an AGM by the way).

Is there anyway to tell if I have the regulator change / software update before I go shouting at the dealer ?

cheers.

Do not think so but it should be listed on your chassis number on the LR system so you could call any dealer and ask them to look up if it has been done , but you also need to make sure the car has been told that it has the new battery.

Mine also had a dodgy connector block that caused a problem from the VR and the dealer to all there credit found this even though the system said there was nothing wrong dealer even replaced the battery a second time at there own cost i might add before they spent hours diagnosing the connector block with voltage meters [/b] Far to many gone...

awsome. Thanks - I'll make some enquiries and report my progress.

Thought I would update folks with this one....the problem continues.

So, since you last tuned in, the car has been to two dealerships. Both allegedly cant find a fault.

I'm not sure how they are testing but I suspect they are merely plugging a computer in that says "no" rather than actually performing real world tests.

I can repeat the problem every day. My main crux is that as winter approaches I wont be able to use the park heating which is an option I held out for while looking to buy a car.

The car is driven for about 45-50 mins each day- should be more than enough to make sure the AGM battery is topped off.

Each morning I try the park heating / cooling which according to the owners hand book should run for 20 minutes. I'm lucky if it makes 14 minutes and usually cuts out before 10 minutes with a low voltage message displayed on dashboard as soon as I get in the car.

Landrover technical are involved......who say "computer says no"....
Local dealership says they cant repeat problem and it works fine for them )???!!!???

Landrover incidentally tell me that for the first 8 minutes of any start from cold, the battery management system never charges the battery e.g.....if someone did just short trips each day the battery would never receive any charge at all. Sounds iffy to me that.

A new battery has been put on, all software checked up to date, BMS calibrated to the new battery (twice). No excessive current drain while car is asleep. Altenator producing charge levels as specified.

Not sure where I go from here. Any help appreciated. Am I the only person with this problem on a 2011 MY?? If as landrover say "it is normal operation " then I would have thought anyone from 2011 onwards would be up in arms about this..

cheers

1 / The software update did mean that 11MY on cars only runs PH for approx 14 Mins , which i think was and is a joke as it will not warm the cabin in that time or de-ice the car.

Someone in the know may well have the answer to this as i see it as " not as sold, as the function was downgraded and now not fit for purpose " !! Far to many gone...

Seems I upset someone

Technically illegal in UK to leave a car running while un attended and in fact last year my wife got a knock at the door at 6.30 in the morning with a bobby standing there having a go at her lecturing her about the dangers to pedestrians / environment and the risk of theft etc etc. He could have ticketed her then and there but he said this time he would let her off with a warning...but next time !!

(shame the bobbies weren't so eager to come knocking on my door a couple of years ago when my car was vandalised )

So, solution was to buy a car with a park heating.........well, that was the idea.... would be nice if it would work as specified though.....clearly I am too demanding !

...besides if I can have an extra 10 minutes in bed on a cold winters morning...I'm gonna do it !

As far as I am concerned this is below par from RR.

Suggestions to improve it :

- install a second gel battery in the rear right hand cubby hole and wire it into the 100 Amp connection there. This should theoretically keep the battery voltage higher for longer. Not sure whether the ECU will "know" that but worth a try.
- install a CTEK charger connection and hook it up.
- put a small electrical fan heater in the car (behind the seats or passenger foot well) and hook it up to the mains with an extension cord. Cheap and nasty but it works, I used it many many years ago during a particularly bad winter in my Triumph Herald. The car didn't heat very well at all but it saved me scraping the ice off.
- install a fully fledged Scandinavian/Canadian heater system and hook it up to the mains every evening.

First solution is the least "extra work" but not sure if it would work as I don't know how the ECU controls the running time of the FBH, for example is it voltage or time based or a bit of both or does engine/coolant temp come into the algorithm as well. MY 2010 5.0 SC Galway green and sand interior!!
Have the Faultmate MSV2 Extreme to be tinkering with the settings etc. !!

The Park Heater is the best accessory on the vehicle  2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

yup it's a great bit of kit

works superbly on the Disco and the Sport Far to many gone...

mine must be the odd one out because its working fine - kiss of death now for when the really cold weather arrives  2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

soooooo......

While it could still be a technical fault with the car electrical system (most likely) , if I understand correctly, LR did a software update to shorten the park heating to run for only approx 15 mins instead of the 20 that it says in the owners handbook. mmmmm

Well as I said, mine only seems to run on average for 10 mins (or less) and then the low voltage message pops up when I get in the car. So I'm still not getting the length of time the revised software says I should get....

I should add that park heating is just the main issue I'm concerned about. but of course I get the low voltage message (which is what this thread is about) when I use anything on the car that causes a battery drain when the engine is not running. For example any combination of radio / deployable side steps / TV/ electric windows / courtesy lights etc etc will all in practically in no time at all cause low battery message to be displayed (the battery is fine of course and engine starts absolutely normally). For example the other day I was cleaning the inside of the car with the radio on to listen to. Now I know the radio times out after a while anyway, but after 10 mins the low voltage message came on when I opened a door to deploy the side steps....which then refuse to work of course due to the low voltage panic.

If not an electrical or mechanical fault with the charging then the software has a lot to answer for being far too protective!!!

The trick is how do I get LR to either fix the electrical fault if it exists or to revert the software to an earlier version !....

As I said...their diagnostic kit shows "computer says no", thus getting them to actually get a good old spanner and screwdriver out (and a volt meter ) is likely to meet some resistance. And of course because "computer says no" on the diagnostics, it is likely to cause them to refuse any part replacement under warranty....

Thanks all.
