Thought I'd encountered a new problem last week. My car went in for it's first service which passed without any issues. However, Eco Stop and Start hadn't kicked in since. I had turned off the fans and air conditioning which didn't make any different whatsoever. So booked car in to get it checked out...
However, the day before it was due to get checked, I had driven 100 miles to a friend and then around 3/4 on the way back, Eco Stop and Start kicked in. It seems that this system has to meet a particular level of parameters before this kicks in. One of them being the battery needs to be at a certain level as we all know, Stop/ Start constantly draws from this.
Ok, it's not the be all and end of everything but my argument is that it's a new car and it get's used every day. Could be 10 miles,. Could be hundreds. Therefore the battery should be constantly topped up. Would make sense if the car hadn't been used for a week. When it's working effectively and taking an average of 100 miles, stop / start could total about 15mins.
So next time Stop / Start appear to "stop working" for you (ECO light flashes 3 times) don't panic. Here's a quote from Wiki about Stop Start system:
Factors like having the air conditioning on impacts on the battery too.Start-stop systems are heavily reliant on the battery. Testing indicates that AGM batteries diminish in their ability to support start-stop functionality over time.
