2017 A4 coding tweaks

Here is a lighting diagram for the taillights, if someone wants to start cracking, all these numbers coincide with PWM numbers in module 46 and have 3 different values attached to them, (A4B6US you'll recognize these) I don't know the security code for 46 however and I believe you need them to change anything. And just so you all know #6 and #11 are the brake light, but its also the top part of the dynamic turn signal, so I don't know how we will get the brake light to go off while the other stays on during signaling.
Here is the breakdown so there is no confusion:
2: Driver side reverse
3: Driver side signature light (the "C" body segment)
4: Driver side signature light (trunk segment)
5: Passenger side dynamic turn signal segment (trunk)
6: Passenger side brake light/upper dynamic turn signal segment
8: Driver side rear fog light
9: Passenger side reverse
10: Passenger side signature light (the "C" body segment)
11: Driver side brake light/upper dynamic turn signal segment
14: Passenger side signature light (trunk segment)
15: Driver side dynamic turn signal segment (trunk)
16: Passenger side rear fog light
17: High mount brake light

Also, in the more recent builds (for the Q7 at least), this function was already enabled. So depending on how recently your car was built, you may not need this coding to have front parking sensors come on automatically.

Great post! I didn't touch those (yet) and I'm still waiting for erwin to have wiring diagrams for the US B9 (Q7 4M are out there but they were not mom much use) so that I can see if they are hard wired together (somehow). Shouldn't, because the turn signals are dynamic but who knows. VCP has some scripts to change the rear lights from NAR to ROW and vv. but that didn't do anything when I tried it (didn't ask for a code though). I'm also eying some ROW rear LEDs from DE as Christmas present to myself, the amber turn signal are just so much better.

On the topic of making Lane Assist wait a little longer before it starts bothering the driver, this might help (mo time right now to test this myself and no idea how this looks in OBE11):
STG A5 - Frt Sens. Drv. Assist - Adaptation
2. ORIGINAL - UDS Adaptation Channel: IDE05984-Directional stabilization assist driver inact deactiv threshold
Stored value Medium
2. MOD - UDS Adaptation Channel: IDE05984-Directional stabilization assist driver inact deactiv threshold
Stored value Late

And another one, not sure if that's of any use:
STG 5F - Coding - enable "byte_24_VZA" (OBD11?) to run on (nav data based) speed signs in the MMI if VZE is enabled in the VC/HUD
