Hey,

I am in the middle of switching to an M-box ECU and the only DTC i can't figure how to code out is the following:

17881 -  EVAP Leak Detection Pump: Open Circuit

        P1473 - 35-00 -   -

European models do not have a EVAP Leak Detection Pump. Any ideas?

Thanks

Do you happen to know the address of CLALPDE in an M-box code i don't see it in any XDF files, I can only see CDLDP.

Thanks

I don't think this will address the 'Open Circuit' DTC.

Sure, I would do that, but I can't seem to find that map in any of the xdf files available for the M-box, that's why I would like to know the address of the MAP so I can add it to the XDF.

Ah, I see. But it still tests for open circuit, it just doesn't store the error.

ESKONF change will remove valve from open circuit testing.

Offtopic: Maybe you know some way to disable postcat o2 sensor open circuit test? Or rather all the tests related to postcat o2?

And do you have the address of ESKONF in the 2.7T M-box file?

I have a value of 170.0 at that address. Does that sound reasonable?
