BMW O2 Sensor Replacement, 2 Series, B47 Engine, 220d, 218d, 3 series, F20 F22 Lamda

How to replace O2 lamda sensor. Should work for most 1,2,3,4,5 series.

[@kevin0036]

is there also a lambda probe at the end of the catalytic converter? because the engine warning light relating to the lambda sensor downstream of the catalytic converter shows me..
(I have a 125d 2019)

Can this make the car not starting?

[@erdemdogan7528]

[@SedatBinici-rk3fg]

This Lambda after Cat ? Or before

[@johnwayne8]

before I guess

How did you know it was an 02 sensor fault?

I believe you also have to reset the EMS module after replacing the Oxygen sensor.

[@IC.XC.NI.KA.]

So why has this failed prematurely??

Thanks man

Its the egr valve mate, not the O2 sensor,
There îs a BMW recall For that, egr valve and egr cooler
Also your car has 2 o2 sensors, one before dpf and one after dpf
Hope that helps

B47 Engine has 1no O2 sensor, which he replaced in the video.

@@petrohasan sorry, mate, 2 o2 sensors, one before cat, and second after dpf, they both work together, to reduce nox level, good for environment, bad for the engine.
