Can Bluetooth be deactivated in a D4
Hi folks, I have a strange situation where a customer is having problems with his cranking battery going flat in a few days, no matter how long he drives for, or how often he charges his cranking battery.
He has one of these SMART Electric Meters fitted to his house and I suspect this may be the problem as I have come across the same situation before and the problem was resolved when the owner of the D4 moved to a new home, which did not have a SMART meter fitted.
The problem appears to is caused by the SMART meter because it continually transmits Bluetooth signals.
This in turn continually wakes the D4 up and hence the problem with the battery going flat.
So is there any way to temporarily turn the Bluetooth off in a D4?2008 TDV8 RR Lux + 2009 D4 2.7

Tim .. You can with the appropriate diagnostic tool
Alternatively get a most loop ( about £15 ) and bypass the module completely ( you can pull the fuse once looped out )G4 Gone ...but not forgotten

Stray bluetooth cannot wake the vehicle, even one paired to the vehicle cannot do this. I suggest his problem lies elsewhere.
Is he a forum member? If so I am sure we can guide him through some diagnostics.

Thanks wiggs, and Hoped to hear from you.
Where would I get this “most loopâ€.
Hi Robbie and I have had the problem before, and it was only by accident that we ( I and the customer ) work out that it was the SMART meter causing the problem.
The guy had had his D4 for about 6 months when he decided to fit one of my kits.
With in weeks of fitting the dual battery kit his problems started.
The guy only drove his D4 about 3 or 4 Kms a trip, every few days, and then a long trip on some weekends.
Over the next 18 months, his battery would go flat in a few days and everything was tried to fix the problem.
The dealer replaced the battery twice.
My isolator was disconnected on a number of fix attempts.
The CUT-OUT level of one isolator was set higher and so on.
Tried getting him to keep the D4 remotes at the other end of the house.
Nothing solved the problem and he had to have the D4 jump started on a regular basis.
Then during one of many, MANY phone conversations, the owner told me how he had gone to a mates farm, some 800 KMs away and the D4 had been parked for 8 days.
Thinking he was going to need to jump start the D4, he had his mate bring a tractor and jumper leads to the D4, but it fired up first go, with no assistance.
During this same phone conversation, he also told me how, out of total frustration of having to continually jump start his D4, he started backing it into his garage, to make it easier to connect the jumper leads.
Not once while the D4 was backed in, did he have to jump start.
So after more than a fortnight of backing in and not needing a jump start, thinking the problem must be resolved, he took to driving front first into his garage and with in two days, the battery was flat again.
I had just seen something on TV about the problems SMART meters were causing, so I asked him if he had a SMART meter fitted to his house and if so where was it.
He did and it was on the other side of the wall of the garage, about a metre from the front of the D4.
Furthermore, it was fitted to the house just after he fitted my dual battery system.
A few months after this conversation, the D4 owner moved to a new house in another state and I have since heard from him and he has never had a flat battery since he moved.

Did not think the smart meters used bluetooth as the signal is too short and easily blocked thought they used wifi. As said my phone will not connect to car or wake car via bluetooth once it has gone to sleep. StrangeMY17 D5 1st Edition Namib Orange

MOST loops can be bought from ebay and alike - they look like this:
But to identify the circuit and system that is drawing power try the link in my signature below.

The most powerful Class 1 Bluetooth transmitters claim a maximum of 100m, but in practically the effective range is much less. Class 2 and 3 transmitters have a shorter range still.Land Rover - Turning Drivers into Mechanics Since 1948

I'm surprised that Utility smart meters would try to use Bluetooth, it's really not a very good medium for that kind of communication. It may have a theoretical max range of 2km but in a built up area the signal would soon be absorbed by the buildings
Here in the UK and from what I've read, NZ too, uses Cell phone technology whereby the meter sends SMS messages. It maybe that if Bluetooth is used it's talking to an internal unit which relays to the utility.
I agree with previous post even if BT signals were close by, its unlikely wake the vehicle because they wouldn't be using the same network protocol, and it wouldn't be "paired", so should ignore.
I use this MOST loop no idea if they are available in NZ.
Good Luck Cheers, Chris in Cambridge

Many of the these new SMART meters used here use Bluetooth as the communications system, to and from the locale electrical authorities.
And yes, it was strange the first time, but now it looks like another similar situation.
Hi Robbie and thanks for the info.
Sorry here in the UK I would very much doubt that you could get 2KM let alone 200 meters, as others have said ina ideal perfect world that may well be possible but in reality that would not work, to my=uch interferance, too many buildings, to many other signalsMY17 D5 1st Edition Namib Orange

Hi Folks and as far as Bluetooth technology goes, I know very little about it, hence the question here.
Prior to seeing the info in a news report, I was under the impression the maximum range was around 100m and even then that was line-of-sight.
But we all know they never get news reports wrong.
In the case I came across, the range causing the problem was just a few metres and there did not seem to be any other explanation for both the problem and the solution, which was to move the vehicle away from the SMART meter.
As far as the testing the Bluetooth goes, at the time, my RR was in use and it was a pain when locking the vehicle and going inside.
My phone would remain permanently connected and unusable until I either turned the phone off and then on again, or walked to the other end of the house ( about 40m from where the RR was parked).
Now as posted, I have a similar problem with another customer, and if anyone has any suggestions, I am only too happy to read them.2008 TDV8 RR Lux + 2009 D4 2.7

Tim, if we can isolate which system or circuit is drawing the power I am sure it can be resolved.

Is there any way to disable the bluetooth on the smart meter? Even for a short period this would dis/prove the theory?
It may well be that the smart meter provider may need to reconfigure their kit as this may cause problems with other bluetooth equipment.De-Tango
