I have a 20 plate custom bought from new,I drive to work ach day between 8 and 12 miles to my first job,with minimal stopping,then I clean between 15 and 20 houses and then drive home.
Van is hardly ever used at night or weekends,van is now 13 months old and has 14 k on the clock
During the winter months heater and fan is on and also heat seats.
Approx 6 weeks ago stop start stopped working,I had to wait all that time to get a slot for them to look at it as I needed a loan vehicle
When I picked the van up they advised the stop start had stopped working as the van was not going on long enough journeys to keep the battery charged above the level for the stop start to keep working,they have charged the battery and it's now ok.
My way of thinking stop start is fitted to vehicles to reduce pollution so perfect if you are sitting in city traffic ie London but if you are and the stop start is on and off all day and you live in London it will soon stop working due to lack of charge going back into battery.
My wife has ans Audi on a 66 plate with stop start does similar journey to me each day apart from the 15 to 20 jobs but has had no issues with stop start
I'm not really buying what there saying to me so and feedback would be appreciated
