    My car is an E46 bmw 318i se DEC 2001 born date.
    It has the N42 2litre engine and done 114k miles.
    Recently the check engine yellow lihght came on while driving on the motorway.
    I used an AUTEL maxiscan MS 309 reader to read the fault codes -it came up with the generic P0420 code-which means "catalyst system efficiency below threshold bank 1".

    In the Freeze- Frame section of diagnosis -it came up with the following-
    FUEL system 1-CL,
    FUEL SYSTEM2-CL,
    LOAD -PCT%-16.5,
    ECT(DEGREE F)-216.
    SHRT FT1(%)-2.3
    LONG FT1(%)-3.1
    SHRT FT2(%)-86
    LONG FT2-(%)-0.8
    RPM-3650
    VSS(MPH)-76.

    Can anyone help with interpretation of FREEZE /FRAME DATA?

    I hve erased the codes and reset the check engine light successfully.

    could be a lambda sensor fault, can your scanner not read the BMW fault codes?

    n,o it only brought up that generic code P0420 one autel maxiscan ms309 tool.

    my peake research tool is coming up with a 10 E -link-up error and hence am unable to get a bmw specific fault code analysis.
