Oh yes stuck in the tea time traffic as I call it and the old girl chucked it. Driving along quite the thing mother chatting away then the big red battery warning light on the clocks (W211 E220). Then revved high wouldn't change gear eventually died 
Thing is I still had full electrics ie nothing going dim (apart from me) but wouldn't start to come out of park.
Eventually after sitting about 5-10 minutes wondering whether to call the AA and get her a taxi back home.... it started!! and got us back but me having 1 eye on the clocks waiting for it to come back on and 1 eye on the rd, anyway..
I've been checking the voltage etc
With everything off the battery's reading about 12.3/4, with engine on but no load is about 14.2/3 with full load on ie both heated seats, heater full, radio, lights, front and back fogs is reading about 13.7ish
Could I say it's charging ok but probably need a battery it's I think it's the original ie 800 amp Varta. I would ideally put at least a 900 in plus a new alt for good measure.
Or is the charging ok?
