Not sure what to tell you about the air quality sensor fault, but second fault is purely an advisory thing; it tells you that at some point the seat heaters were shut down to conserve the battery's state-of-charge.

Thanks for correcting my post Uwe. I thought I could get away without the CODE thing- but it does make reading it easier!
The Air Sensor fault is a new one that I've not seen before- so I will keep an eye on it. As for the other, it didn't occur to me to run the German error through Google Translate. It makes sense now: "Seat heating - comfort restriction due to intervention energy management".
