Sport Stereo/intertainment

Hi I have a 2014 L494 RRS every time I touch the door break when driving the dab radio station drops out and if set on fm station it’s just a crackerling noise as soon as I depress brake pedal it returns to normal. Anyone got any ideas please.

What is a "door brake"?

Sorry predictive text (foot Break!!)

Most likely the antenna amplifier in the rear spoiler as that's the only shared bit of the DAB & FM receivers - needs fault codes reading and a few other checks to confirm. It could also be the high level brake light, the grounding straps on the liftgate hinges or a few other things - but a DTC read and a few basic checks will narrow things down.

I'd suggest trying a different predictive text engine or deleting all the 'learned' words in yours....
