    hello peeps,

    just did a lowline to highline conversion of the central elec module on my a4 b7(swapped a K module for a N module)...but my rear fogs no longer work...and the coming home function i installed only the rear lights work for it...nothing at the front (LOL thread on here has been bashed tryna get them to work) but neway...after doing research on the module swap i found that the wiring does vary slightly from low - high...was wondering if anyone had both wiring diagrams with the pin layouts so i can compare and see what needs changing?

    found some old threads of people who have done this but the links for the flow diagrams are outdated and no longer work.

    any help would be much appreciated as ive got my MOT coming up and need the rear fogs to be working

    thanks

    I take it you've had it coded to the same it was?

    this is the wiring schematic that gaz initially posted for the ch/lh wring...ive decided to check the whole diagram to my car as his is highline.

    everything is the same apart from:
    J519 pin 30 ------> e491 pin 3 should be a wire
    my pin 30 is EMPTY and pin 3 on e491 has a grey + yellow wire but havnt followed to see where it leads

    &

    j519 pin 29 -------> pin 7 &15 of E1 should be a wire
    all 3 Pins are EMPTY on mine.

    These are the only 2 differences? would i possibly need to run additional wires to replicate the diagram?
    cant find one for lowline to beable to compare them...

    Sorry to dig out the old topic.

    Did you manage to sort this out problem.
    I did try the wiring you mentioned, but still doesn't work.

    Could you advise me how to solve this rear fog problem, please.


    Thanks.
