SC Derby 259 Posted February 11, 2018 Got a couple of lovely Mazdas in at the moment, both 2.0 Sport with the start stop or as Mazda call it 'i-stop'. Both seem to flash up i-stop on the dash, I think its a warning related to the second battery, anyone had any experience of this? Would it be Mazda only or can normal diagnosis machines pick it up? Any help appreciated before I ring the main dealer Share this post Link to post Share on other sites

sparky 274 Posted February 12, 2018 7 hours ago, tradex said: Maybe worrh investing in a cheap battery drop tester, such a useful quick n dirty tool that will pay for itself after the first battery you needlessly change.....off flea bay for less than £20 delivered. Used ours last week to chase out a fault on a Picasso which, you would of thought screamed battery, but was in fact starter motor..which was cheaper than a battery...strange but true. 607's used a 'service' battery which usually failed before the starter battery, so could be an easy fix Oh stop it. 607's, what a car.

SC Derby 259 Posted February 12, 2018 Looking like the second battery is low on charge/not holding charge, but not 100% sure yet. I think they are going to try charging it and go from there. Share this post Link to post Share on other sites
SC Derby 259 Posted February 14, 2018 Mazda 3 - battery tested fine, fault cleared, not come back on as of yet. Mazda 5 - both batteries knackered, changed and now fine. Not sure if the electric doors or other gismos have had a bearing on the batteries. 1 Share this post Link to post Share on other sites
