Lower heat temp while passengers airbag is off

[petrik25]

I have 2.0 tdi pd mk2 octy and have noticed something I have never heard of before. I have noticed my heating was not hot enough even when on maximum. Just sort of luke worm. I do have little baby and I have switched off passenger airbag. I was loosing my mind why I don't have hot air, checked water levels, thermostat and was going to mechanic to chcek exchanger. On the way to work today I thought let's switch airbag back on, as I don't want to explain why it is off. And who-a-la, my heat came back to normal, toasty hot.

Anyone else noticed it or knows something about it?  

Could anyone try it and post it his/her findings?

It's no consolation, but I have my airbag switched off, and the heater is still as warm as ever on my Mk2 FL 2.0 PDI BKD.
