RANDOM HEAT

2003 BMW Z4

Heater problem
2003 BMW Z4 6 cyl Two Wheel Drive Manual 34,000 miles

I have noticed that my heater started only heating when I accelerate the vehicle and at low speed and idle it only blows cold air?
Any Ideals

It could be the IHKA module requires recoding. There aren't bulletins that speak to the issue you are having.
