Knock sensor common failure on F30 328d?
Just had a CEL come on for about a week and went away afterwards. Car still felt like normal when driving on the streets and highway though.
Dealership said the error code said it was a faulty knock sensor. Is this a common issue on this engine of ours? Is there a DIY on replacing it for future reference?
Edit: looked at the paperwork and it's the Nox sensor
