Heater help
 

Hey guys I'm a noob here! Anybody had problems with they're heater? I've got a 525 blows hot air unless I'm on the freeway

So the air IS hot but then goes cold on the highway? Did you mean to say that it does NOT blow hot air until you are on the highway?

Are you in Manual or Automatic mode? If Manual, check the override settings in iDrive. Someone may have moved them into the Red (Hot) zone.

I have checked the settings in the I drive menu and it blows warm air while idling as soon as I get on the freeway air turns cold
