Hi

My 2017 HSE is only a few months old and now the auto start/stop does not work. The car is warm enough, not cold outside. No climate control or heated/cooled seats. No radio or Bluetooth is on and it wont work. Basically it should be working. Its definatley activated. Try switching on/off. It used to work all the time.

Any insite before I take it in to be looked at?
Thanks!

I have the same issue, I bought the car at the end of December and it was working fine, even if the AC is on. Then when summer came it does not work again till today.

Yes same here - mine is a 2016 and after it received the new software patches, the auto stop/start does not kick in much.
I may see it happen about 10% of the time now.

Maybe it's because people last year were complaining it kicked in too much ?

I know I hated the early version where it shut down every time I stopped in bumper to bumper traffic.

Now it's nice not to have it be so intrusive.

I like it!

mine hasn't worked since I got the car-

had all the standard excuses given to me- my theory is that there is either the gateway module or some type of control module stays on when the car is turned off. This drains the battery sufficiently to inhibit the stop/start technology but not enough to warn you that you have low battery..

There are about 30 odd parameters that need to check before stop/start will work-

Problem is that when these dudes check your car at the dealer, they turn off all the mod cons, like auto lights, auto wipers, climate control, heated seats etc etc...then reset battery monitor system and surprisingly stop/start works. As soon as you drive out the dealer and put these systems back on- it fails...

at the end of the day stop/start maybe saves you $50 US a year on fuel- so not worth it in my opinion, however, its a principal, the car is installed with this technology and so it should work as designed..My wife's car has so much more tech than the Disco, never had an issue with stop/start not working with all the mod cons on...

Same issue here. It does work occasionally, but nowhere near as often as when the car was new. We have a 2017 HSE that we got in November last year. We have not been to the dealer since, so no updates have been applied. The system has just decided to not work most of the time.

....
Yes, this is the cause.
I just confirmed this with my service advisor when I mentioned my auto start-stop has been working too much...
My post on the second round of service campaigns:

Item number one is the culprit!

yep- Im arguing with my dealer

they say:

1. gateway module operates ok
2. Battery charge system works Ok
3. all other control modules work ok
4. battery is not faulty

yet

battery is on low power so stop/start won't work.....

So, they can not explain to me why the battery has low power if all systems work properly.....so they conclude there are no issues, even though they admit stop/start isn't working.....

just sent my car back to the dealer- told them I don't want it back until they fix all acknowledged issues (I have plenty more)

I have exactly the same issue with HSE MY16 model. My service advisor said that all the tests come back fine and no faults and said maybe I used it too much in traffic from Monday to Friday city driving around town. Doesn't it defeat the whole purpose of 'stop start' if I don't use it in traffic ?!? It really annoys the xrap and frustrates me so much that the function is not designed for city driving - if that's the case, I certainly wouldn't use it on the highway then why bother have stop start button and function?!?

^ yes why bother!

I'm tempted to just disconnect the auxillary battery to prevent the auto start stop from kicking in period!

Hi all. New here, first post as my DS is currently in the service centre getting a couple of things looked at (lots of subjects for other posts). One of the issues I have is the stop/start doesn't activate nearly as much as it used to. When it was new, it was annoying how much it happened, then all of a sudden it stopped. I would say I can count on one hand the number of times it has kicked in over the last few months.

What's the general feedback? the stop start drains the battery, when it gets too low it doesn't kick in any more? is it the primary battery or i see someone mentioned an aux battery? (didn't know there were two!)

I had an interesting comment when I brought it up with the service adviser when dropping it off, she mentioned "oh that happens, might need to keep it overnight for a charge"

If it's that simple couldn't i just put it on a charger at home?

Welcome aboard!
I experienced the same issue.
Then after it received a battery update software update from LR:

Q634 Gateway Module Stay Awake - Battery Drain - software configuration

This appears to be the culprit in having your car awaken and drain the 12V auxillary battery (the battery used for auto start/stop). It has nothing to do with the main 12V battery.

Check with your service center if your car will receive the Q634 update.

I looked up all the specs for the car and there does not seem to be an auxiliary battery as in some vehicles with start/stop.

"The battery is an H7 80 Ah, 800 CCA Absorbed Glass Mat (AGM) Valve Regulated Lead-Acid (VRLA) battery on:
All vehicles with auto stop/start system.
All vehicles with Fuel Fired Booster Heater (FFBH) with Cabin Heat Function.
The battery is an H7 80 Ah 700 CCA Flooded type battery on:
GTDi 2.0L Petrol engine vehicles without auto stop/start system.
AJ200 Diesel engine vehicles without auto stop/start system."


A separate electronic device is provided to maintain proper voltage to components.

"A Voltage Quality Module (VQM) is equipped to vehicles with the auto stop/start system. The VQM is located adjacent to the
Central Junction Box (CJB), behind the glovebox. During an auto stop/start engine start cycle the VQM maintains some of the
vehicle’s electrical systems by supplying a support voltage around the vehicle's electronic components during an engine
restart. This allows crucial vehicle systems to continue uninterrupted when there is a sudden draw of current from the battery."

Same issue occurred for me. I brought it in for its 20k oil change and they fixed it. Not sure what they did. But no extra questioning or issues.

They did some new squeak update... I swear I now hear a squeak that was not there before. Uggh! I am afraid to tell them because I think they believe I am crazy with all the minor goofy issues I have experienced with this vehicle.

I would delighted if my stop/start did not work in our 2017 Land Rover Discovery Sport.
How can I achieve this?

I've just been told my battery needs replacing because the stop start will fail if it holds less than 75% charge.

Not even 2 years old, and almost every battery comes with a 3 or 4 year warranty.

So.............what is the best way to make a claim against Land Rover direct for fitting a dodgy battery when new?

Hmm first thing I would do is go to a dealer.

Hi, I am a new owner of LR DS 2017 model HSE (Petrol). It seems no body knows what going on with the casue.
I experienced the same problem here in Taiwan. Actually they are many DS owners have this issues and the dealer cannot do anything to fix it.
I think this can be a generic problem that LR needs to fix.

The stop/start on my DS works for first 2 weeks when I got it and they fixed it, saying the battery output current is not enough to trigger the function. Then after 2 weeks the car got returned, it stopped working again. I am going back to dealer again next week.

Some people here finally got fixed with a battery replacement with bigger capacity. Some people didn't get it fixed after several times trying.

I wonder if LR knows te real cause until now. It's been 2-3 years the DS launched and LR should know the problem and fixed it. It's really a disappointment. This really damages LR branding already.

I do so many short trips I am surprised the car even starts some times:D I had even set up my headlights to maximum delay when turning off the engine ( a few weeks ago), so every time I parked the car in my garage the headlights would come on for a long time. Never mind the heavy rains that have caused headlights to come on at noon some days. Set the delay to 30 seconds and now no problem with start/stop. Extremely short trips followed by 2 or 3 days not driving does not make a happy battery. :(

No problems with my car with the start/stop other than my style of driving the last few weeks.

Oh! not battery current, it is battery voltage that the system looks for.

After mine had that battery drain update done, the auto start stop had started to work again (not ideal).
But then after a couple of months I noticed it would not work.

I am quite happy with that - I don't like the auto start stop as it creates a delay in moving while stuck in bumper to bumper driving in Southern California....

Next time it's at the dealer, I won't mention to them that it does not work - I prefer the auto start stop to be gone....
