Lamda/O2 post cat sensor part no.

[inkey$]

Hi all.

I’m trying to locate a part number for my E86. Am after the O2 sensor after the car on bank one of my engine. Any ideas and recommendations of online purchase options?

Audtodoc do a Bosch universal sensor. Post cat, banks 1-3.

Check on Realoem site for p[art numbers, put last 7 letters and digits of your Vin number in on the home page to display parts listing for your actual car. Just checked out a 2007 Z4 3.0l as an example here https://www.realoem.com/bmw/enUS/showparts?id=DU52-EUR-06-2007-E86-BMW-Z4_30si&diagId=18_0652
The universal ones come with a plug you have to wire yourself, for a little extra you get one with the correct connector already fitted so plug and play. All 4 sensors have different cable lengths so need to make sure you order the correct one.

Hi
I need to change my Lamda/O2 post cat sensor too.
But the price original BMW is too much expensive (150-200 $) and same one universal (Bosch) is about 50$
Do you think wire is different ?
