How to replace engine air filter for Mercedes-Benz E-Class W212 with the OM651 engine. According to mb documents you should carry out a resetting of the contamination level of the air filter. I did some reading about this on different mb forums and is not seems that important, and I have hard to think all independent dealers doing that. If you have some information about it please make a comment below 👍
