    Obvious, about the price.

    However, if what is different amongst them is the plastic connector that doesn't wear it begs the question why give money away?

    Just hooked up the test lamp and got a 1444 which means no failures.

    Fixed with genuine Bosch part but not OEM. However the OEM removed was Bosch too.

    Could you be more specific? Really interested in this, as since replacing my chipped ECU for a standard one, I got this 1221 code and I have a feeling that the O2 sensor is good (it's been replaced last year, NGK one -70 quid).

    Do you think a de-cat would trigger this code? Air leaks maybe? MAF? Any suggestions welcome.
    There are only two products required to make the universe work properly: Duct tape and WD40. 


    If it moves (and it shouldn't): duct tape. 
If it doesn’t move (and it should): WD40.

    Everything else is just stuff.
