Hi All,
The stop/start system on my E220 CDI estate (2012 model S212) doesn't seem to be working, as in, I can't even remember when it last stop/started (at least a year ago), and the 'ECO' symbol on the display is constantly yellow (as opposed to green). Granted, I don't drive much these days, mostly short trips and not many of even them. But occasionally I drive 300+ miles on the motorway, which I would've thought is enough to charge the battery properly etc., but still no.
Anyone know what this indicates? Does the auxiliary battery need replacing? (The car is 8 yrs / 120k miles, and AFAIK the aux battery is still the original.) Or is it more likely to be an issue with the charging system, or the stop/start itself? Or is this just what happens with old age?
Thanks,
robaa
