Body Module Coding

    I had BWW read code faults relating to my headlamp washers - this threw up two pumps, one level sensor and the Body Relay Module: 61351383411 As the costs for the module was horrendous I purchased a second-hand one. Can anyone tell me if this module has to be coded so that it recognises the car has having headlamp washers? As it was second-hand I do not know if the donor car had headlamp washers or not. Thanks :help:

    Yes, the general module (GM), as it is commonly referred to, does require coding unless it came from a car with exactly the same options. Following items might not work without recoding if the donor car was not equipped with it:


    • Sunroof
    • Headlight washers
    • Speed-dependent wiper pressure control (only relevant if the donor module is from the US which did not get this feature)
    • Door lock heating (not relevant to your '99 since the door lock heating coils were no longer installed starting from January 1995)


    Additionally, if the donor module came from a left-hand drive model (assuming yours is a UK right-hand drive model) you will find the window switches operating the windows on the opposite side of what you are used to.


    Recoding the module is very easy and only a few minutes work, but obviously it requires access to a BMW diagnostic system. In BMW DIS/SSS: "[3] ZCS/FA CODING" --> "[1] E31 Series" --> "[1] Recoding" --> "[11] GM (ZKE II)".


    Please note that if the donor module has a software version older than 40 (November 1993) some minor functionality, like triggering the interior lights with the remote keyfob, will not work (not even after recoding).
