Deactivating Rear o2 Sensors with STAR Diagnostic possible?
Is it possible to deactivate the o2 Sensors through STAR DIagnostic?
If so does anyone have the instructions on where to access this in STAR?
My tech with STAR doesnt seem to know where to access the rear o2 sensor codes to deactivate it.
I currently run a catless midpipes and want to get rid of the CEL, so annoying

I spent an hour trying to deactivate the o2s with sds and finally just had Jerry at eurocharged take care of it when he tuned my ecu. He's a gentleman and a scholar.

Dont have the luxury of getting it deactivated by any other than STAR since i do not live in the US ;(.
Ive read post about people saying you can do it by STAR but no one has confirmed it yet so im so confused.

All of the tuners out there do remote tuning, so it doesn't matter where you live.

The 02`s can be altered in STAR but you have to know where to look and how to make that change.

If we turned them off in the code, then you cannot turn them back on with star. I'll need to reflash you.
It's very easy to turn off the rear 02's with star so you can pass emissions. I'll be happy to share.
. I'll contact you for a reflash!
In my C32 W203 i turned them off from 3 years:
development data-ME 2.8-Control unit adaptation-Variant coding- implizite codierung-0224 then code nb 183 for rear o2 sensors and code 178 for secondary air injection
and i don't know if the codes are the same for the w211.
