GTW_w182 park assist not available in combination with PARK_w037_sensorSupplyLow

[16MX]

Hi guys,

my park assist is not working. None of the PDC sensors is working.
Strangely, I couldn't find any useful info on the PARK_w037_sensorSupplyLow error.
Any idea what's going on?

Car parked in my garage for 2 days.
Park assist is working again.
Strange...
