my engine light has come on and says i have a fault on bank 1, sensor 1. it runs fine and is causing no problems but it wont pass an MOT. i have googled it but i am still having trouble locating it? does anyone know where it is? is it easy to change myself? its a 2009 w212.

thanks

Put your VIN number in the box at the top of the page and then look in the diagrams of the engine and you will find the part and its position in the exploded view.
