Thanks & yes a lot of the Audi stuff could be that the person hasn't seen many Euro variants! Bold my comments!
04 = VW Golf Variant (AU)
FA = A
8A = Audi A3 8V (RHD)??? My guess here is that Somnus just didn't have/come across a car like yours when building the spread sheet. Note that many cars use the same code here, 8A for Audi A3 8V (RHD) and 2019 Golf R-Line (RHD)... Golf Variant (RHD) should probably go in the sheet with 8A coding as well.
A1 = U
24 = 288mm (PR.1LM, 1ZE) (need to change this!)
25 = 5
29 = Seat Leon FR/Cupra??? This one is interesting, although Golf Variant isn't anywhere on the list so Seat Leon FR/Cupra as good as any other choice I guess, although the FR seems more Golf hatch-ish. They do an FR estate, what you could call a Golf GTI estate, just the Seats have much cheaper interior trim fabrics & plastics...
6E = 2
03 = Audi A3 8V (DSG)??? The "Audi A3" callout is likely the same reason as in Byte 2, just didn't have the scans available. Both 6MT and DSG would be 01. The "3" in your 03 would be for green auto hold indicator in the dash... which I assume you have? Yes I have auto hold button as well as the electric parking brake button..
80 = 9
06 = FWD (RoW)
09 = 9
41 = Golf R??? Same as Byte 2, lots of cars with 41 in this Byte.
C8 = 5
29 = 272mm w/Multi-Link Rear Suspension (PR. 1KE/1KT/2EJ)
20 = Seat Leon (5F)??? This is just the mirror of Byte 0
51 =??? Mirror of Byte 2
24 = 288mm (PR.1LM, 1ZE) (need to change this!) Mirror of Byte 4
94 =??? Mirror of Byte 6
C0 =??? Mirror of Byte 8
60 =??? Mirror of Byte 10
82 =??? Mirror of Byte 12
94 =??? Mirror of Byte 14
F3 = Will need to change this as the car now has 135kW & not the 103kW it had from the factory! You could go F7 for 135kw. This is what I was thinking of doing!
F4 = Front ACC, Front Assist, Trailer Assist, PLA 3.0 (typically see this with 12 sensors, but PLA 3 works much faster than PLA 2 so that should apply with 8 sensors as well, possibly better with trailer assist as well) I have front assist & ACC, & yes the 8 total sensors..
20 = Starting Torque for 1.0/1.2/1.4/1.6 Gassers, if your car now makes 2.0L gasser power you could change this to 10 I suppose. Again another one to change!!
50 = Bi-directional wheel speed sensors left and right, with multi-link suspension. Cars with parking ACC and/or parking aid will have bi-directional sensors. Agreed & correct
78 = TPMS with Radio, radio in this case being infotainment based on PR code. Maybe determines how the ABS sends tire pressure faults/info over the can bus.
C0 = ESC Button and TPMS button (in this case meaning button function is duplicated via infotainment). I have Bit 1 enabled here, so my coding is C2. EPB engages if I unbuckle while stopped. I might try some other variations to see what is possible. I think I set this when I retro-fitted the ESC & TPMS buttons, can't remember though!...
09 = Determines what the ESC button does for single press and long hold... in your case ASR (traction control) off on single press, ESC Sport mode with long press. That is what I set it too, as factory was different..
