I have a 2016 insignia 1.6 cdti v-xline I've noticed for the last 3 months my stop start is not coming on any ideas what could be coursing the problem 

It could be battery health/condition as if not fully charged it will knock out this feature.
Give the car an extended run and see if it comes back online after that

My auto stop/start,stop working after I took it in for mot and car services.it was working before 2 weeks ago,when it went for mot and services,it passed too

I have same problem just been to Liverpool and back still not working

Check the battery is fully charged and delivering the power the system needs to operate.
Also, if it has discharged in the past (e.g. during lockdown) then the battery charge may need resetting via a scan tool for the vehicle to know the new voltage (e.g. post lockdown)

Hi I had the same problem when I bought my 17 plate, apparently the battery is failing not holding its charge it may be 100% charged by the charger but is it holding 100%, it may be only holding 70% and for the stop start to work it needs 74% of a good battery. So difficult to explain, anyway,

New Battery is what mine needed

Absolutely crazy system used by Vauxhall, I have the same problem on my  2017 Insignia VXR,but my 2019 BMW 740d  stop/start system works within 5 mins of the engine being started even if the engine temp is still cold.

I guess if you want perfection you need to stick with the Germans, i was looking to part ex my VXR with a Vauxhall dealer who then offered me just over half of its value which i declined,so i guess thats my punishment for not buying German............... wont be making that mistake again 

I have a 2014 SRI CDTI ecoflex insignia and I have not had my start stop working only if I stall the car.

Battery 12.8v

Had aircon off 

Radio off over 1/4 of fuel.

Its its just not working done everything I can think of even when coming to a stop from costing to a stop to putting the hand brake on before going into neutral but still nothing can anyone help in this matter please.

I miss my BMW and my Audi A6 both worked fine with stop start but this car doing my head in just can not get the stop start working at all.
