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!

I think its the Mercedes me app on your phone is making the engine noises, if you have Bluetooth audio turned on, then it will come through the speakers.


I threw my adaptor away months ago as it is completely useless, it give absolutely zero useful information and the connectivity problems just made if frustrating.


Don't get me wrong, I love my GLA220 4MATIC, but I hate the adaptor.
