one of the o2 sensors failed last week, so changed both of them today to be on the safe side. both new from bmw.

cleared the fault codes from the car, took it for a quick spin, plugged it back in to make sure there was no more faults codes present and lo and behold have these 2 on it now………..
(won't let me upload pics for some reason)

1……...Lambda control stop (bank 2)

2……...o2 sensor heater circuit (bank 1, sensor 2)

anyone shed any light on this? did I get a fault sensor?

it a 98 323i.
