Hi, It's been really cold past two days here in Ottawa (-22c feels like -32). Unfortunately, I don't have a garage and I park my M3 outside, both at home and work. Last night and tonight when I insert Wall Connector, it clicks 2-3 times and little T symbol blinks in amber instead of green. In addition I get "Limited Charging - Charging rate may be limited due to cold temperatures". Has anybody else experience this. Last night it did stop charging by itself at %55 even though I set it to %80. Do you know what is the best practice to preheat the battery? Should I keep the climate on? Your Advise is greatly appreciated. Note: I have a 32Amp Wall connector and it limits to 16 Amp in this case.
