Hi everyone, my e46 325i with the mentioned above engine was consuming 22 liters per 100 km, we dropped it to 18 liters/100 km by disconnecting the O2 Lambd sensors, engine is in open loop mode now.

However, 18 liters for city and 17 liters on a highway for 100 km is still too much of fuel consumption. What can I do to drop it to factory settings mixed 9.5 - 10.5 liters per 100 km?

Engine is at 209k kilometers.

Thank you in advance!
