In my MQB workbench I use the message WBA_03 (0x394) to control the gear position displayed on the cluster and it seems to work perfectly so I'm surprised that another CAN bus message could also work, even partially. Did you try to send a corresponding WBA_03 after the 0xAF to see if the selected gear stops flashing? (maybe the cluster also responds directly to the gear selector but needs some kind of confirmation from the mechatronics, but that's just a guess). I have no idea about what message would be expected to release the gear lever lock solenoid, but probably it's something from the gearbox (the mechatronics module controls the variables related to "gear lever lock" and changes the values as active/not active, for example, when you press the break pedal when the car is stopped). Since you probably won't include a real gearbox in setting (even though your "weird shit" seems very impressive) maybe the easiest way to work it around would be opening the gear selector and finding a way to disable the lock permanently.
Looking for some CAN bus data of PQ and MQB platform cars

Yeah, it's not 0x394 - I was fully expecting it to be at the start, but apparently not.
I did some more experiments and figured it out though. With the help of our friend opendbc. They now have a MQB DBC.
The CAN address that does the magic is 0x128. Three bytes in length, but only byte 0 is important. Bit 0 is locked/unlocked (1 being unlocked) then bits 4-7 are the highlighted gear.
Bit 1 is supposed to control something about the backlight, but doesn't seem to do anything for me - though I did wire the dimming/backlight terminal directly to 12V, so that might be the reason.

i have some GB of data from my skoda octavia VRS, PQ35 2010. its sniffed from motor can.
I can upload it if you want to exploit it.

Hi! Yes if you can that would be nice. I am still looking for some information for my Superb 2 cluster, and Octavia probably shares a lot with that.

Here is some. i made new yesturday to the dashboard. can send u that also in a few days
Thank you! Yeah, the convenience can for the cluster is probably even better source since it has some information not present on the drivetrain one.WeTransfer | Send Large Files Fast - Up To 2GB Free

Any chance of a re-upload please?
I am also still searching it.Any chance of a re-upload please?

Maybe 1194 RPM?
From the bytes 3 and 4 you got 0x8e 0x81, mask it with 0xff 0x0f and swap the bytes and you get 0x01 0x8e which is 398, multiply it by 3 and you get 1194 RPM.
See the attached photo from the "official" DBC file.

What do you mean? Decoding method is just above your post.
This is correct !From the bytes 3 and 4 you got 0x8e 0x81, mask it with 0xff 0x0f and swap the bytes and you get 0x01 0x8e which is 398, multiply it by 3 and you get 1194 RPM.

1224 RPM 0x107 0x00 0x00 0xfe 0x97 0x01 0x35 0x49 0x0f
1947 RPM 0x107 0x07 0x00 0xfe 0x89 0x82 0x35 0x02 0x78
Tnank you very much !

Go figure. He said its the official dbc file. Why wouldn’t be correct?
I think in CAN-K ID's is
0xFD // speed/distance
0x31B // speed on kombi
I can make a log file from my car.
