E92 320i 2AED 2CAA fault codes

E92 HSP · 12-13-2022, 02:15 PM

Hi guys,

I recently picked up a 320i (N43 72K on the clock) and I did a quick fault code scan and 2 fault codes popped up.

2AED - Nitric oxide sensor, version
2CAA - Lambda probe before catalyst, temperature

Cars running pretty smooth still.
I have noticed an increase in fuel consumption.

What would be my best line of attack?

Update:

Changed the pre cat O2 sensor for cylinders 1 & 4. Running perfectly fine now.
