My 2013 C-Class Coupe has recently been flashing dashboard warnings. Firstly the 'tyre pressure inoperative' warning, accompanied by the yellow engine management light in solid yellow. This proved to be not a problem at all and correcting the tyre pressure removed all warning lights. At that point I suspected a faulty sensor somewhere. Now it is showing the yellow engine management light in solid yellow and nothing else. The car runs perfectly. Is there a quick fix for this as I don't believe the car has anything wrong with it and I would prefer to keep the £500 the dealer would want to diagnose this. The common loose fuel cap doesn't seem to be the issue. Thanks
