The chargers had been removed from the M-CHARGE app on 2025-04-14.
They re-appeared only now. There are 2 new DC chargers, and the old AC number 1 is back as number 3. The other AC seems to be gone.
The closure was probably entirely due to the charger upgrade, as I cannot find any other information about the shopping center closing for remodeling.
The pictures of the parking entrance visible on the store website and on Google Street View says 2.1m height limit, Max. Parkzeit 3 Stunden. Parkhaus schlieest 30 Minuten nach Ladenschluss. It doesn't seem like there is any gate. Parking is probably free.
