This is my third time going back to the mechanic and we cant solve the prob.
I keep on getting p0155 and i know its the bank2, sensor 1, upstreams (driver side).
The light came back again this morning after 1 day getting my car back from him.
Im using bosh sensor 16318.. The car hesitate when the light gets on !
What am i doing wrong?

Thank you in advance!

so you guys know, I took it to a diff shop and tested every single wire /fuses and everything was fine.
At the end, he swapped the relays from left to right and vice versa and solved the prob so far.. i drove the car 140 miles today and nothing came on !
Im ASSUMING prob solved. (keeping my finger crossed )

I've also been plagued with this code for a long time now.

Which relays did he swap?

Till today no prob at all
Open the hood, and open the box of fuse and the box of the ecu.
if you look there is one single relay in each box that both r identical, swap em and see what happens. I hope it solves your issue!
