bimmerguy 6 Report post Posted February 24 Model: 2010 116i (N43) I got my car serviced recently and a few errors were encountered related to the NOx sensor as shown below. 12 Engine electronics 3 errors 2AF4: 0x2AF4 nitrogen oxide sensor, electric 2AF2: 0x2AF2 nitrogen oxide sensor, Lambda linear 2AF6: 0x2AF6 nitrogen oxide sensor, Lambda binary My mechanic mentioned this is very common for N43 and isn't critical, hence, it can be fixed during the next service. The car runs mint, however, I would like to get it fixed soon with the NOXEM. Has anyone used this?, if so what are your thoughts? Cheers, ~VD Quote Share this post Link to post Share on other sites
