my90 S smokes in the inside. I was told that there's a problem with the heater core and AUDI should fix it for free. anybody has any idea about how to fix that

 

Replacing the heater core in an Audi can be a real bear. The rigs with climate control heating/AC are an all day job. The smoke you see is steam from a pinhole in the heater core. Audi won't fix it for free -- heater cores corrode internally over time like radiators and sooner or later need replacing.<img border="0" src=smileys/smiley6.gif border="0">
