    Hi All,

    My 1995 405 glx estate with XU7 - 8 valve tends to pink when fully
    warmed up on a long run. The engine has done about 60k miles from new
    and performs well in all other respects. the ECU is a bosch model 5.1

    Does this engine /ECU have a knock sensor and correction capability?

    I have downloaded the error messages from the ECU and there are no
    problems logged. In the manual, there is a code for a faulty knock
    sensor but I don't know if I have one fitted.

    Where is it and what does it look like please?

    As I have phobia about going anywhere near Pug dealers, I'd like to fix
    this by some other means.

    Anyone else have this problem? Shall we form a support group?

    Regards

    Bob

    Hi All,

    The XU7 has no knock sensor, only the XU9 has a knock sensor.
    The temperature of the engine is still ok ?

    Best regards,

    Michiel

    Thanks Michiel,

    The engine temp seems about normal, perhaps a few degrees cooler than it used
    to run.

    If there is no knock sensor,is there a way to adjust the timing to reduce the
    pinking?

    TIA

    Bob
