S63l M157 - P2097 Error Code
P2097
Hi guys my CEL came on, ran a obd scanner and got these error codes, anybody ever ran into this issue and can guide me please?
I'm assuming it could be my O2 sensors?

Pretty sure Bank 1 is passenger side btw
does it have a stock exhaust ? Stock tune ? If its stock check the downpipe to turbo connection, the flex pipe, flanges, v-bands, check out bank 1, and do it cold. If there's an exhaust leak you'll likely hear it cold start
Can you do a live data read of the rear o2 sensors ?
Update:
So my right catalytic converter was on its way out, under load/heavy driving the smell was more apparent than driving normal/casual.
I ended up going with a decat downpipe 😅 no more issues with cat in future now.
My turbos are alot happier now 😁
