I had my GLA 250 4matic serviced just over a month ago. Since then when I move off, and at other times during a journey, I hear brief engine revving noises COMING THROUGH THE SPEAKERS! Also my reversing beeper volume is reduced and sounds a bit strangled.
I have tried in vain to speak to a Mercedes technical expert for answers. Has anyone else experienced this?
I have tracked this weird behaviour down to the Mercedes Me Adaptor that was fitted at the same time! When I unplug it the noises etc. stop!
