Hi, only picked my e220 bluetec yesterday and this afternoon the engine management light came up and checked with torque app and its code p229f, I do intend to phone the dealer tomorrow to find out to get it sorted after a search it seems the nox sensor, I did put some Wynns injector cleaner is this something that could have set it off, the car is low mileage and I did almost 100 miles yesterday, car drives amazing but worried at what this could be
