When I recently (after 12 months) got the latter, the dealer treated it as a fault and updated the software in the 'smart charge' system. According to them, this is a common fault, which results in the battery only charging at 12.4 volts instead of 13.8 volts (as they tell me it now does). Since then, I've had no '3-minute' warning.
It shouldn't be a major problem unless your battery has been completely flat as a result of inadequate charging, although I'm not entirely convinced that long-term charging at an inadequate voltage is good for it.
Thanks I will defo mention it at the service now

They changed the battery on my first Evoque at the 12 month service too.

Correct on all fronts. If you are consistently getting the 3 min warning you need to have your battery checked. Furthermore ALL cars brought in to have the "software update" need to have their batteries tested before handing cars back to customers. Clearly many dealers are not doing this.
And, long term charging at inadequate voltage will, eventually, kill the battery.

+1 I'd never had a flat battery just the 3 minute warning and they still replaced it.

If you like i will check and see what i did to fix the car i had with similar problemHi mate ours is having this 3 minutes warning nearly every time had new battery, full system upgrades 10 days ago, full rest all to no avail hade in the past abs fault gearbox fault now been in 10 times for this fault did you ever get a cure? thanks.

The same by me, but when using Auxiliary heating. I switch it on and after maybe 3 minutes the message "after 3 min.......blablabla" appears.
Tommorow going to service, technician said, maybe they will replace the battery.
We will see

Is the auxiliary heating a big power drain? (In other words, could it be a valid warning in this case?).
RE: Low battery warning without the engine switched on - jojosr - 03-12-2013 06:27pm
I do not think so, today I was in service and they just load the battery (no replace).
Technician told me, that to compensate battery drain by auxiliary heating (or cooling in the summer) is neccesary usually to drive the same time as using the heating. That means, if using heating 30 minutes in the mornig I should drive at least 30 minutes afterwards.
We will see, if the draining will continue....
