No Heat suddenly after flushing cooling system

I have a 745Li and I just replaced my radiator hose both upper and lower as well as the overflow box and now I cant get any heat in the car is thei related. The overflow is at the corret level and I'm no longere seeing a lowe coolant level alarm. Help I'm freezing!!

With the car cool, remove cap from reserve tank turn on heat to full leave fan on low. For about 5min or so.... Then turn on car and watch for air bubbles comes out from the small pin hole in the tank , return cooling line. If that's not working for you, it might be your Aux pump that feeds your heat cord.

If you had head prior to changing out the hoses then I would think your system is air bound.
Follow what the other post said. I swapped out the T-stat on mine and it took awhile to get all the air out. Had the same issue on our M Roadster. Threw a belt and slight overheat. Lost coolant. Replace all the pulleys and belt. On her car I let it sit overnight with the Rad cap off and topped it off in the am. No issues as of yet..

Opps. HEAT, I meant heat!!!!! to funny
