"Low Battery, Please Start Engine" message....

Post by RegG » Wed Nov 21, 2018 11:58 am

When my 2017 Sport HSE has been standing for two or three days without use, I can open the drivers door, or the powered tailgate, then a message flashes up on the display telling me the battery is low and to start the engine. This message is accompanied by a bleep. If I have opened the tailgate it will not close automatically when I press the button - until I start the engine.

The car is going into the dealers for it to be looked into but I wondered if anyone else had experienced this problem.

Thanks for the reply. I was wondering if it could be software...... when I booked it in the receptionist said a software update may be required. They are also going to look at the offside rear window which is being temperamental - sometimes the 'one touch' close works, other times it doesn't! Apart from these two problems the car seems to be going well but I do miss my D4 which was stolen in the middle of the night just about a year ago never to be seen again :(

Yep get the latest software updates is always a good start.
Sorry to hear about the D4 .....make sure if you have keyless you get a good quality faraday pouch for your keys , don’t forget the spare needs one too!

Thanks - both sets of keys in faraday pouches and a stop-lock on the steering wheel! Plus tracker at the insistence of the insurance company!

Hello,

I have had that problem for over a year. The car has been in to the dealers a few times and the issue has never been resolved.

I have had software updates and various parts of the electrics replaced including the battery, header unit and parts of the alarm. Its always worse when the weather is cold but I will say that the car has never failed to start even when the car has not been used for 4-5 days.

The Start/Stop rarely works so I know there is something going on but as the car has never broken down and always starts I just accept its part of the cars personality.

I've just had the same issue.
The battery was fine and fully charged.
LR Assist came round and he cleaned the contacts around the back of the battery. He said that if they get rusty or clogged with dirt, the sensor can read that the battery is not charging. Since then I've had no problems, fingers crossed.

I had the issue for a while. They replaced the battery then told me the new battery had gone flat overnight while still at the dealers. They did several software updates and claimed it was drawing 2 or more amps while shut down. They kept it for several days testing it, they never did give a satisfactory (to me) answer as to what caused it. They tried very hard to blame it on faulty workshop test equipment saying the tester was causing the battery drain...

My DS150 is now 3 years old, hence out of warranty. Despite having all the updates the 'low bat' warning keeps appearing now since last October.

First thing I did was charging the battery. Lasted for two weeks, then the message was back. Charged again, same result.
Next I brought it to the dealer in November to check the battery with one week of warranty left. Next day I was told the battery is like new but was nearly empty. They charged the battery, charged me €80 for their service and I got a lecture about driving style and short trips for free.

Well, the 'low bat' message was gone ... for five days. Since then I charge regularly ...

I have to admit, my DS does some short trips, but it is also used on longer motorway distances and the message also appears after longer trips.
So I´m now at the point to buy a new battery, but I´m not willing to pay Landrover premium prices. The only thing that concerns me is the battery managment system which should be reset when replacing the battery.

So here are my questions:
- Is it definitely necessary to reset the BMS when replacing the battery? I will install the same Varta battery that was built-in from new, so no changes in battery parameters necessary.
- Would it maybe help to charge the battery to full, then reset the BMS without replacing the battery at all?
- Is there a diagnosis unit (like the IID tool) which is capable of resetting the BMS by myself? I have that stuff for my Volkswagens, but unfortunately this doesn´t help with the DS.
- And lastly, what is the best method to charge the battery? Dealer says, directly at the connectors. But I think in this case I will bypass the BMS sensing module resulting in the BMS not recognising the charging at all. Would it be better to connect minus to ground?

Thanks for your input!

So here are my questions:
- Is it definitely necessary to reset the BMS when replacing the battery? I will install the same Varta battery that was built-in from new, so no changes in battery parameters necessary.
Any shunt based battery management system, which the DS BMS is, will gradually drift out of sync with the actual state of charge (SOC) of the battery, so it will periodically recalibrate itself by going through a deep discharge and recharge cycle over a couple of days. When the dealer installs a new battery they will force this recalibration to happen over a few hours. So, if you install a new battery yourself without the tools to do a forced recalibration, your system will be out of sync until such time that it does one of it's periodic recalibrations and then all should be well.
- Would it maybe help to charge the battery to full, then reset the BMS without replacing the battery at all?
A battery will gradually lose capacity over it's life, and so the voltage may be showing fully charged, but the BMS will be telling the ECU that it's not fully charged because the BMS works on an 'bank balance' basis of energy in versus energy out. So, the dealer can also initiate a 'new battery capacity reset' on an existing battery to reset the capacity figure in the BMS to the actual capacity of the installed battery so this mismatch doesn't happen. Unlike the periodic and automatic SOC recalibration described above, I believe this capacity reset procedure can only be done by the dealer.
- Is there a diagnosis unit (like the IID tool) which is capable of resetting the BMS by myself? I have that stuff for my Volkswagens, but unfortunately this doesn´t help with the DS.
I don't believe so. I think only the LR diagnostics can force a SOC recalibration and capacity reset.
- And lastly, what is the best method to charge the battery? Dealer says, directly at the connectors. But I think in this case I will bypass the BMS sensing module resulting in the BMS not recognising the charging at all. Would it be better to connect minus to ground?
With any battery charger, but particularly today's smart multistage chargers which rely on accurately sensing the voltage and temperature at the battery to determine the charge they put in, it's best to attach as close to the battery terminals as possible. However, you are correct that you do not want to bypass the BMS, so the negative should not be attached to the battery post itself, but to where one of the existing wires bolts on, or if you want to be ultra safe - to where the battery negative wire attaches to the chassis ground point.

I should add that all this is just my limited knowledge of how it works based on having a battery problem on my DS, reading the workshop manual, and what the dealer has said he's done. I cannot guarantee it's complete accuracy.
