    Hi all,
    I'm retrofitting LED Matrix lights to a Q7 4M which has standard LED lights. Just wondering whether anyone has an LED matrix Q7 without air-suspension? The reason I ask is that standard LED and xenon lights have a single level sender connected to the rear axle (rear left) connected to J393 (in boot rear left below fuse block) that sends level information to J519 over CAN which then sends height information to headlight controllers to adjust the vertical beam on these headlights. (feature: LWR) . On the air suspension vehicles, this information comes from J775 chassis control unit and it has FOUR senders connected to it from each wheel arch! In the repair manual it states that the matrix headlights (without air suspension) need also a front left sender (which I have installed) for matrix lights. What is interesting is that the PR codes for the build of cars with Matrix air-suspension and other headlights both state "PR-8Q3 - Automatic headlight range adjustment dynamic (self-adjusting while driving)" but the looms and number of sensors differ depending on the suspension type. In the good old days Audi would have had different PR codes to differentiate the different versions requiring the different hardware but no longer. Obviously in the factory there must be a note that says if PR-8Q3 and Matrix lights PR-PXC (Matrix Headlights) grab loom A but PR-8Q3 with LED Headlights PR-8IT grab loom B.


    Hence, I need to check the coding of a Q7 4M that has matrix lights but NOT air-suspension (J775 module) to confirm the bits that need changing in both J393 (to say it is using two senders) and J519 to accept height information from J393 relating to front and rear height information. I am pretty confident I know the bits that need changing but would like to confirm with a factory optioned car with Matrix headlights.


    thanks

    Not sure if it would help, but I have an A6 with matrix but no air suspension?

    SVM codes for these kinds of retrofits are unknown... You need to manually do everything to install.
