Does your Macan EV keep SoC stable when left idle for a week or longer?

To people with 1% idle consumption:

do you have dashcam or anything that is connected to your car, through USB, rain sensor wire or other powered source that is supposed to be off when the car is sleeping?

No.

do you have dashcam

I do. I'm currently shopping for a logging USB-C multimeter, and a logging ODB2 plug to track activity over time (self powered if possible)

I did check my ODB2 yesterday, and on startup, there's 24 amps going into my 12v battery, and the DC-DC converter is reporting 57 amps of current. So the 12v is certainly a load when waking up to charge it back up. A logger would allow me to see activity over time when the car is entire 'turned off'.

I shall also reduce the dashcam's parking mode time.

One note, my dashcam takes a mile or 2 to get going when I drive away in the morning, which indicates the 12v is quite low.

Previously, I've lost 1%/day a few times.

Last week, I reconfigured my Dashcam parking mode to turn off much sooner than the 24 hours I had previously (with the hardwire also turning off based on voltage), and I also set it to a low frame rate instead of lower quality.

Today, after 3 days of sitting idle over the weekend, I'd lost zero % SOC when getting back in and driving.

Some people are having discharge when sitting idle issue, some are happy to report no discharge. Since I do have this problem, I want to gather some stats before talking to the dealer. Maybe I will find a solution which I'm happy to share here.

My 12 V battery draw is higher than on maybe someone else's car who does not have a dashcam. if the 12V is less used the car should also less likely take too much if any to charge the 12V ...so the SoC loss is less as well. Mine is 1% SoC loss per day as my 12V battery is drained constantly.

No dashcam or any additional accessory on mine.

After last charge to 80% which ended again with being 77% when I got to the car few hours later I am getting range 261km at 10C outside without even putting anything to nav... At that temp car thinks now that to cover 120km on highway (2/3 at 130km/h 1/3 110km/h) it needs 44% of battery.

Still same issue for me. Not possible to charge to 80% anymore. This time it ended up at 76% even though the app told me it reached 80% 8 hours ago. I also experienced a huge drop in range even though my overall consumption actually decreased. At 50% of charge it shows me around 120 km of range which would be 240 km at 100%. Way less then one year ago when at this time of the year I had 350-400 km of range at 100%.
