I just got a letter from BMW informing me of a recall notice. It is recall campaign number 93V-015. Apparently the 1984-1993 BMW 3er may have a cooling system malfunction. They say that if a crack were to form in the end piece of the heater core, coolant could be expelled, perhaps spilling onto the leg of the driver. Also, coolant could be expelled from the heater core as vapor and fog up the windows. I was wondering if anyone on this board ever had this experience with their M3 (or is it a non-M3 problem) or have had the service done. Thanks.
