O2 sensor (lamda) is the most neglected item coz even it is deteriorated, the engine will still run but not at the optimum level. But then, O2 sensors are pricey in Malaysia (for e39 with BMW logo made by Bosch RM1,200 each and OEM by Bosch RM520.00 each). Bought mine online from a USA site for USD 69.00 each.

bro Herbert, you bought yours with BMW logo for that price or OEM by Bosch? I wonder how much the E46 will cost?

after changing, i am averaging about 450km for same amount of fuel.. i will continue monitoring.

I just changed the O2 sensors. But the OBC reading is 11.4l/100km, previous reading was 11.9l/100km. Is it ok? I run on 19".

 

[Herbert]

Zun,

You need to reset your "Consumption 1 or 2 " at your OBC.
