Hi all first post so hopefully in right forum to ask this. I’ve got a 2014 actros mp4. I know the engine should only start on the button when brake pedal is depressed but for some reason it will start not only on the button but literally starts when I press the brake pedal only! Obviously a bit of a safety issue. Before I put it in the main workshop I thought I’d see if anyone else had had the same problem. Thanks all in advance
