Reply To: Blue light on power supply (PSU) stays on

Hi David,
This is normal. It means that your battery voltage is sufficient to keep the parking mode active. It will not drain the battery. If the battery voltage gets too low, the blue LED will go out and the parking mode option will be automatically disabled.
With BMW, the voltage on the yellow wire (depending on where it is connected) remains present for another minute. After that, the K5 also needs another minute to switch off. So it is correct that the K5 only switches off after about 2 minutes.
