Serious challenge for BMW technicians
I have a 2010 BMW X1 23D xDrive.
There is a howling sound from the HVAC (Heating, Ventilation and Air Conditioning system) BUT only when I brake or decelerate. As soon as I accelerate again, it disappears completely. It also disappears completely if I turn off the fan, so it is not the brakes. No one can figure it out - be the first please 👍 |
