Hey couple issues with the Beemer cant seem to figure out first cold starts -10°to -20° dr seat heater goes off when first pressed then stays on after about 5mintes passenger ok and radio goes off and on randomly until warm (battery ? cold crank amps are around 675 ??? )

next thing is driver front centre left heater vent blows hotter are then passenger side have to increase temp setting on passenger to equal heat sometimes almost cool air

any suggestions would be great

Only thing I can say- Next time you replace the Battery put the H8 (900 CCA) size instead of H7 (790 CCA). An H8 will fit you move the bracket over one. You may already have that because you are in Canada and the cold. Here in the US most e39 have H7s in them. I put H8 in my e39 and the H8 was less $$ than the H7... Go figure.
