Anyone experienced this - eco stop start not working on newly bought car, not an AGM battery me thinks
Fast forward 5 months and the stop/ start starts to work
Any ideas why?

Warmer weather might help.

How old is the battery? Procrastination, mankind's greatest labour saving device!

My stop/start is really unpredictable when it works and when it doesn't. You never know when you take your foot of the clutch whether it is going to stop or not. It's quite annoying but there is no easy way to disable it that I know of, except pressing the ECO button every time you start it.

It definitely works more often in warmer weather. I think there are quite a lot of factors the ECU takes into consideration including battery charge state and engine temperature. It would be nice if it showed you on one of the displays how it has made its decision whether to do stop/start or not!

I must be quite lucky as I find the start stop to be very predictable and pretty much cuts in every time I put it into neutral. It even surprises me when the engine has bearly been running with no much engine temp and it still cuts in.

The other day I found it quite interesting at a drive through window it didn't cut it until 30 seconds to a minute after we had stopped, whatever condition it was waiting for was met and randomly switched itself off.

I do generally prefer to run with the windows open rather than the AC so maybe that has something to do with the start stop cutting in so much. Also I run the heating control on manual when it's a warmed day so the car isn't trying to keep the interior cool.

First thing I do when I get in is switch off stop/start - same in the Honda!

@Dean - I have read that keeping aircon on (or leaving on auto and allowing it to do it's thing) helps to preserve the seals in the system, a lot of AC problems seem to stem from people not using it 2014 Freelander 2 TD4 Manual Dynamic

Thanks all - as I thought it probably computes it's own ideas based on a number of factors including usage of high draw items like the heated seats my wife has on constantly until summer

Yes, the car was stood on the dealers forecourt for a while and it's been cold of a morning up here, so the CCA have been required of the battery coupled with short journeys and few miles - ave about 500 a month only
I think the ambient temp, battery condition and CCA demand are both improved hence the ECO stop start kicking in
I thought it might have been disconnected by removing the lead to the small back up battery in the boot

I have been trying to find a brief description of the workings of the Stop/Start.

The Repair Manual returns 158 hits on the query "Stop/Start", it seems that just about anything, except perhaps the radio, wants to effect the Stop/Start system.

For further details you need to get out your FL2 Repair Manual and settle down for a long read.

Repair Manual extract

STOP INHIBITORS, START INITIATORS AND START INHIBITORS
A number of selectable features or vehicle situations can influence the operation of the Stop/Start system’s operation.
These can, depending on the particular circumstances:
prevent the engine shutting down (stop inhibitor),
initiate an autonomous restart (start initiator),
prevent an engine restart (start inhibitor).

Stop Inhibitors
Under normal circumstances the Stop/Start system will automatically shutdown the engine if:
the vehicle is stationary,
the transmission is in neutral,
the clutch pedal is fully released.

The following conditions will inhibit the engine from shutting down:
Driver effected stop inhibitor
The following driver effected conditions will inhibit the engine from shutting down:
Driver switches off the Stop/Start system
Transmission not in neutral
((note that the driver resting their hand on the gear lever can move the transmission out of the neutral window without engaging a gear))
Clutch pedal not fully released
Accelerator pedal depressed
Hood is open
Driver’s door is open
Driver’s safety belt is disengaged
HDC (hill decent control) is active
TR (terrain response) mode is active
Climate control system used above calibrated threshold
Windshield demist is operating
Trailer electrical connection detected

Vehicle system effected stop inhibitor
The following vehicle system conditions will inhibit the engine from shutting down:
Driver switches off the Stop/Start system
Brake servo vacuum below threshold
Battery cold cranking capability below threshold
Battery state of charge is low
Catalytic converter outside either pre or post calibration range
DPF (diesel particulate filter) is regenerating
Engine coolant temperature below threshold
Engine oil temperature below threshold

Environmental effected stop inhibitor
The following environmental conditions will inhibit the engine from shutting down:
External temperature above 35°C
External temperature below 4°C

Start Initiators
When the engine has shutdown within a Stop/Start cycle the following conditions will initiate an early restart within the
same Stop/Start cycle:

Driver effected start initiator
The following driver effected conditions will initiate an early engine restart:
Driver switches off the Stop/Start system
Vehicle speed above calibrated threshold 3 Km/hour (2 mile/hour)
- A restart will only occur if the transmission is in neutral and the driver’s presence is detected for example, the
driver’s safety belt remains secured and the driver’s door remains latched
Brake servo vacuum below threshold (driver operating brake pedal)
HDC (hill decent control) is activated
TR (terrain response) mode is activated
A higher heater fan speed is selected
Windshield demist is activated

Vehicle system effected start initiator
The following vehicle system conditions will initiate an early engine restart:
Battery cranking capability is near its lower threshold
Battery state of charge is near its lower threshold
Windshield demist activates
The interior cabin temperature decreases below or increases above the occupant’s set thresholds

Environmental effected start initiator
The following environmental conditions will initiate an early engine restart:
External temperature rises above 35°C
External temperature reduces below 4°C

Start Inhibitors
When the engine has shutdown within a Stop/Start cycle the following conditions will prevent an automatic restart:
Driver effected start inhibitor
The following driver effected conditions will inhibit an automatic engine restart:
Hood has been opened
The accelerator pedal is depressed
Gear selector moved out of neutral; message Center will display: ‘Select Neutral To Restart’
Driver’s safety belt is disengaged; this is an automatic start inhibitor therefore the engine can be restarted by
depressing the clutch pedal
Driver’s door is unlatched; this is an automatic start inhibitor therefore the engine can be restarted by depressing
the clutch pedal

Vehicle system effected start inhibitor
The following vehicle system conditions will inhibit an automatic engine restart:
Engine has shutdown for longer than 5 minutes: a conventional restart will be required

As always Ian, a an excellent full explanation of the stop start system.  Now at the point when I learn something new something old is lost out the other side !
Now retired so it doesn't matter anymore.
Freelander now gone.
