Autolink100 34 Posted June 5, 2019 Just been asked to take in a 2014 A Class with this message showing up. The guy reckons it's only been on since someone clouted his door mirror a couple of weeks ago. Looking online it seems to be a common issue across the Mercedes range with it often coming on totally randomly. Anyone come across it before? Share this post Link to post Share on other sites
tradegirl 112 Posted June 5, 2019 We had one and it was to do with the bonnet lock. There's a plastic part where the bonnet lock is located, where one of the sensors had gone. You'd shut the bonnet and the warning would be on, open and close again and it would go off. So it might be a case of changing that part or the complete bonnet lock. There's a lot online about it, others say to have someone push flat the inner bonnet release while you shut the bonnet. Lastly, check where the bonnet hinges are, there's a plastic round plug on either side of the car where the hinges meet the wing. If those round plugs have a silver cylinder poking out, the car has had some sort of a bump and they've deployed. Hope this helps. Share this post Link to post Share on other sites
