I have a 2012 E220 Cabriolet in the UK and have an Engine Management light come on the dash. I have interrogated the fault with a TopDon fault analysis tool and it gives the following. What I want to know is how easy is it to fix, can I do anything myself or what are the likely costs to fix it.Vehicle Information
