Snap On Modis Users

[Cisc0]

I recently got a SES light and upon scanning with a Snap On Modis with the BMW chip I got codes 227 and 228. I have searched on here and have found nothing stating what these codes mean and I tried google but I'm coming up short. If anyone can shed some light I would greatly appreciate it.

Thank you in advance.

E3 = 227
E4 = 228

O2 Sensor adaptation limits cyl 1-3 and 4-6 if Table 18 is the correct one to use

Thanks for the information.

Got to the bottom of the culprit, my fuel filter. The thing was super clogged up and therefore causing the codes and SES. Installed new filter and man what a difference.
