Thanks for the quick reply. The battery is original, so it's about 3 years old. But, I don't see how it is connected to the air suspension?

While a failing battery can cause strange electrical issues, the symptoms you described point to a faulty bellows valve. Given the error codes and physical signs, I would recommend having a qualified mechanic inspect the suspension system, especially the air bags and valves. A professional diagnosis will confirm the cause and the appropriate repair, and should provide further insight into the battery.

Appreciate the advice. Took it to the shop, and it was indeed the bellows valve. Replaced it and all seems good now. Cost me 590€, which sounds reasonable. Thanks again!

I had a similar issue with my Sienna. If your error codes point to the valve and you're experiencing those symptoms, a defective suspension airbag valve is a strong possibility. How old is your battery?
