This is after 2 flats last week!!
Problem is I often use the car for work & leave it unlocked while using it & open doors etc though this shouldn't be allowed to be a cause to flatten a battery = modern technology I guess!
The AA man sugested fitting an AGM battery as fitted to the Stop/Start cars.
My understanding is that the AGM batteries are required as standard fit for any vehicle that has stop start, but most importantly energy recuperation. These battery technology has spare capacity to store the extra energy gained from recuperation. This i believe means that the battery is not fully charged as the normal ones are. To stop this flat battery problem some cars like Volvos with stop start run a small motorbike type 12v battery in parallel so that when the engine is off the accessories don't drain the main battery.
I have been lucky I have done 27000 in ten months and I have very little in the way of accessories and not had any problem.
The manufacturers are all playing the game of the least amount of drag on the alternator, hence smart charging, this is what is causing the chaos.
It might be worth checking what battery you have, I don't think the auto has recuperation so could use a traditional battery. You will see the AGM logo on the side of the battery.
I would prefer having a traditional type battery too, i have recently had the scary moments too. i have done about three different trips abroad recently and had to leave the car in an airport carpark only to return late at night, so far all has been ok with no warnings. Didn't like the feeling though. We shouldn't be scared to leave a car in this day and age.

Just had my Evoque in at Lookers Park Royal for messages on Terrain Response Programs not available. While investigating that they also found that the battery was very undercharged. They investigated further and applied a new software update for battery charging and replaced the battery with a new one (all under warranty). All seems okay but it's interesting that there appears little mechanical work these days but everything centres around 'software updates'.

Just got back from the dealer. they fitted a new battery (were going to fully charge the original & tell the BCU a new one was fitted) & did a software update.

Took our car in for a service yesterday and mentioned the comments raised on this thread to the service department. They told me they checked their system and they could not see any references to this issue or aware of similar customer complaints.
They fully recharged my battery but said this was happening due to not enough long journeys. The irony is my journey is no different in the last 4 years and previous vehicles never had this issue.
I average about 1000 miles a month so I'm not sure what is considered the optimum weekly milage to keep the battery in the safely charged.

Show them the technical bullitin in post #64 above. It really annoys me when dealers deny knowledge of known problems. Come on dealers come clean with your customers. We are not the naieve idiots you seem to think we are

I will be copying this to hand to my dealer at 1st service in Feb. I have so far not had a re-occurance of the '3 minute warning' since it was last back at the dealers for a 'fix' but I don't trust it.
How things have changed at dealerships. Twenty/thirty years ago you took a car to the dealers with a fault and were meet with the comment "They all do that mate". Now the quote seems to be "Never heard of that one before". Whichever way its BS and great forums such as this help to expose it as such.

I was told that the update to the BCM was (and I direct quote) "Nothing to do with your battery issue".
like I said, I'm not a fan of coincidences!

Alex.
We had a similar problem with our BMW 330i Coupe.
BMW said exactly the same thing, we pointed out that the car was being driven exactly the same as our last 5 cars, never had a battery issue with them, it was then that they changed tune and said that the car had a lot of battery draw due to all the various electronics and other systems running in the background.
It does seem odd that cars are no longer off even when they are turned off.
