4 Zones problem, help!!
My car is equipped with 4 zones climate, but recently the vent in the rear right side is blowing some HOT air even when my temperature setting is "LO".

This occassionally happens to me, although I haven't seen it happen in months. I've seen many variations (such as hot air in the back during the summer, cold air in the front during the winter). It goes away after a restart. I've never bothered to have the dealer look at it, since it is totally random.

Happened on my E55 once and took it in. He replaced a blower or something like that. It was a pretty hefty bill from the looks of it luckily it was under warranty. Hasn't happened since. Have your dealers check it out.

Went to dealer this morning and they run a test with Star Diagnosis. They said the setting temperature of the 4 zones were mixed up. So they made a resetting of the 4 zones by the computer. Now it's back to normal. The dealer told me that they have experienced this problem with the W211 every once a while. They fixed it within 20 minutes and it was free of charge
