    MK7 Foglight Check Bulb

    Hi all,

    A little background on the car --it's a 2015 US Spec Sportwagen S. I had the CECM replaced to include the pinouts for the foglights and have fitted the following:

    CECM part 5Q0-937-087-S
    Front fog lights to pins B5 and B45
    Rear fog light to pin A72
    Euro switch 5GG-941-431-D WZU (with Auto setting and a piggyback light sensor) pin 5 to A29
    Enhanced Auto Dim/Homelink Mirror part 000-072-548-E (this connects to the headlight switch, more below)

    So I have the light switch wiring as follows:
    Euro switch then the piggyback light sensor plugged into it, then the homelink sensor piggyback, then the original plug that goes to the CECM.

    I've got everything adaptation coded and double checked with a bunch of my notes and posts online and DV52's lighting guide and I still get the "Check Fog Light Right/Left" when I am in the Auto setting of the switch and the ambient (sun/shade) lighting changes --typically will see the error pop up when the headlights are triggered on by the sensor.

    The behavior I would see with my first set of bulbs (Nokia H11 2500k) was the fog lights would come on but then flash a few times, stay on, then cut off. I can turn the front fogs on forcibly by having the switch pulled all the way out to turn on the rear fog lights. I then switched bulbs for PIAA H11 2500k ones and the flickering went away and the fog lights will stay on but I still get the Check Bulb warning.

    I've attached the faults here:

    I've uploaded my Channel 09 Adaptations here: https://www.dropbox.com/s/2muojbnejn...-0051.CSV?dl=0

    Anyone have insight? I am starting to think it's an issue with the Euro AUTO switch setting and light sensor (I've been troubleshooting this problem for a month now).

    Thanks!

    ^^^Hi and thanks for posting your BCM admap.

    Your leuchte-programming changes look OK (to me, at least) - assuming that the retrofitted front fogs are not LED (Nokia H11 2500k??). I wonder whether the problem is caused by your curious DoT rule that enforces a maximum of 4 x lights (I have never understood the road lighting rules in your country)

    Anyhow, I notice from the code-string on your BCM admap that the car has incandescent headlights - so, try changing IDE04924-ENG115860-Driving light and parking light-Zahl der aktiven Scheinwerfer auf 2 limitieren (my bad translation "Driving Light and parking Light -number of active head Lights ON limit 2") from limitieren (current) to not active.

    Hi DV52!

    That is correct, I am not using any LEDs for the fog lights, Nokya and the PIAA are halogen.

    I don't have a "not active" setting but here are my two options for that channel:



    EDIT: I tried this setting and I still get the warning indicators.

    Hmm..... that's strange because I just checked the specs for your new fogs and they are 55W - the same as the factory lamps

    You could try shutting down the lamp monitoring function in the 2 x Leuchte-sets - but it addresses the affect of the fault, rather than its cause (not something that I like!)
    Anyhow, pending better advice from anyone else, it's done like this:
    • ENG116948-ENG116102-Leuchte12NL LB45-Fehlerort mittleres Byte DTC-DFCC 12 > 0
    • ENG116949-ENG116121-Leuchte13NL RB5-Fehlerort mittleres Byte DTC-DFCC 13 > 0

    No luck with that one --I tried inputting 0 and it gave me an error:


    I input 00 but I still get the Check Bulb Warning.

    I entered 0 and the message I got was the screenshot. I entered 00 hoping it would have the same effect as 0.

    ^^ got me stumped - Ive changed these exact channels on ALL 35 x Leuchte-sets on the BCM on my test bench without any problems using both my HEX-NET and my HEX-CAN cables.

    And, a setting value of 0 is acceptable for the Fehlerort mittleres Byte DTC-DFCC channel on your BCM (look @ ENG116950-ENG116140-Leuchten14AL LB6-Fehlerort mittleres Byte DTC-DFCC 14 on your admap)

    How would I go about getting a fix for this? I have set this value to zero a few times before but I only have access to the latest VCDS release or the beta release.

    Some difference in the firmware between the module you have on your bench and the module Chimuel has?

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.
