DS7 e-tense 2019-2021 traction battery recall

I got the recall notice as well. Just took it in, and they said only the software needed to be updated but there is an error code indicating the “secondary” battery has a problem and needs to be replaced at a cost of €200 (plus tax) which is not covered under warranty. Apparently this error appears when they start the car. Thisis new to me as I have never had this error appear before. Has anybody else had this problem? Could the software update have something to do wit it? By the way, I am in Portugal.

buongiorno,io sono in Italia, e dall’app My DS non si rileva nulla a riguardo della batteria secondaria.Ma negli ultimi 2 mesi la ricarica e ’ calata del 30%, prima facevo 55/60 km, adesso ne faccio 40.Vi sembra normale?

Cold temperature has a clear negative effect on battery performance.
I’m getting around 30 km now, but it’s probably a bit more cold here (+6 C right now).

Yeah totally agree.
Not only has the mileage on mine dropped from 33 to 26 after a full charge, it seems to use this charge more quickly without achieving the lower predicted 26 miles.

Mine DS4 shows 50km (31mi) but I try to finish charging about 30-45 minutes before the trip. Outside temp. about +5

Whats the reason to complete charging 30-45 mins before the trip .
Just curious.

On cold days, the coolant is likely also heated while charging the traction battery to ensure the battery reaches its optimal temperature and charges as efficiently as possible. Therefore, terminating charging shortly before a journey will reduce energy loss while driving. The battery’s cooling system serves not only to cool the battery but also to heat it. This depends on the outside temperature.

Great tip, keep them coming :+1:
