    Hi all. Just run dis v57 on my mates 2002 318 coupe after his eml light came on.
    There were two error codes.

    2727 dme oxygen sensor ageing after cat conv. Bank 2

    2722 dme oxygen sensor before cat bank 2

    My question is, should he just buy a new o2 sensor or will something else be broken causing the o2 sensor fault.
    Thanks in advance.
    Edit.
    Can anyone advise on how many o2 sensors in total because dis states that the pre cat sensor is the one throwing the light and the post cat sensor is ageing. Any help appreciated. Thanks
