    2007 audi a4q cabrio no reverse lights

    The issue is i dont have reverse lights. I can turn them on via the 519, but it never sees "reverse lights active via can" mvb 9 at the 519, i think mvb 9. it sees brake lights active via can. It sees reverse and all other prndl features in the cluster, trans, engine, abs. I tried a new 519 module and noticed this car has had new headlights put in that are not bi xenon when i went to code. I tried the different coding options, there is no coding option for no xenons and a us car. headlights and other lights work fine and i tried disconnecting them. I also noticed the cluster coding was questionable on the first coding option, its a 007 but seems it should be 001, that it wont accept. Im at a bit of a loss here, wiring diagram show one wire coming out gear position switch that seems the be the info line for postion that does not go directly to the 519. I feel its a coding problem but cant find an issue i can confirm and change. Thanks for any input.

    Hello,

    The coding of the [09-Cent. Elect.] (J519) does not appear to be able to code out the reverse lights functions. The expected coding for this vehicle's (J519) seems to be [20003]. The coding for the J285- Instrument Cluster seems to be fine.

    The Measuring Value Block group [009], field (4) in the (J519), shows the "Reverse Gear, (via CAN)".
    - This field is not displaying the "activation'" of the actual reverse lights, instead this is the message that has come from the J217-Transmission controller on the Powertrain CAN-Bus via the Comfort CAN-Bus on the J285- Instrument Cluster.

    We had a customer with a 2009 A4 (w/09L trans) that had the same concern, "no reverse lights", no change in the MVB-009 and the obvious Reverse Signal coming from the J217-Transmission controller (see MVB-004, field 3 = Multi-Function Switch (F125)).

    The had informed us that they ended up replacing the (J519) and the concern was gone, Reverse Lights were functional.

    With that said, did you use the same exact part number when you tried a new (J519) controller? Was it 'New' or 'Used'? Part numbers do matter and not all J519s are created equal!


    If the (J519) is okay and the CAN-Bus message for reverse is never making it to the (J519), it is possible the J285-Instrument Cluster is not sending the "reverse" CAN-Bus message? It hard to tell for sure, since you can not really 'see' a CAN-Bus message without an oscilloscope for CAN-Analyzer.


    Before you condemn or replace any controller, I suggest to verify that all the powers, grounds and connections for that controller are 100% correct. The use of the Official Factory Repair Information is highly recommend.


    Hope this helps,

    drpeter
