Check Engine Light - INPA error codes
For the last 2 weeks I have been getting the empty check engine light appear every 5 days or so only to disappear after restarting the car 4 times.
The car seems to run fine and everything appears normal, it doesn't even appear sluggish or anything just the light randomly just turns on when driving normally.
I scanned the car with INPA and got the following error codes..
2AF2 - nitric oxide sensor, Lambda linear
2AF4 - NOXsensor, electrical
2AF6 - nitric oxide sensor, lambda binary
Can you advise whats wrong and whats needed to fix this? i have a 320i n43 2007 69k miles.
