Hi there, i've just got my first X5 and over all i'm really pleased, however just got a couple of que's that i hope someone can help with regarding the AUX heating

i bought my x5 second hand, i know it has AUX heating factory fitted from new but there is no remote control for it, is it possible to just go to BMW and get a new one ??

and am i right in thinking that there is an exhaust blower for the AUX heating that blows out from near the passenger wheel arch or is this part of a more serious problem like my exhaust blowing??

many thanks
