Model 3 - Rear Windscreen Heater Loses DAB Signal


Oct 20, 2020
I had been suffering from DAB signal dropouts and finally realised this morning it is when I turn the rear windscreen heater on. Turned it on/off lots of time and as soon as it goes on the signal drops completely turn it off and within a few seconds it is back on.

Has anyone else experienced this? The car is going in next week for the heat pump repair so should I just add this to the list?

This can happen in any car, especially where the radio antenna is built into the rear glass as it is on some cars.
I have the same problem as you when the DAB signal is very marginal. I'm not sure much can be done but you can ask and see what they say.
