My car (320, M54B22) still suffering high fuel consumption (about 14l/100km) eventhough already changed the DISA valve.
I think the next suspect will be on the sensor since I still have quite some sensor errors (Exhaust temperature before & after catalyst bank 1 & 2) from the scanning result.
Wonder would this be the possible root cause? Where are these sensors locate? Or what are the other possible reason?

Thanks for the sharing, but think the diy not an easy task it'll need some special tool to do it. Guess better way still find an experience workshop to do it.
BTW, there should be total 4 sensors (2 pcs bank 1 bank 2 respectively), right?

Best to get it scanned at the workshop. If the O2 sensor is bad, it'll throw a code.

I'am not sure if resetting the throttle and transmission adaptation could improve your FC but u could try it. Mine is M54B22 year 2003. I can get to about 650+ km full tank cruising on highways, 470+ city driving using RON97.
