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

Not sure how its marked up as solved, but it isnt. It is booked in on Friday though so will see what they say.
 
They are replacing nox sensors for me next week, can't wait to get it sorted as I'm looking at a possible remap

This has finally been replaced today, nice to be driving a car with no fault code for the time being.......
