Hi all,
I’m running an EMU Black on a Seat Leon 1M (Golf 4 platform / PQ34), engine code AUQ (1.8T 20V).
The built-in “CAN-Bus dashboard: Volkswagen” preset keeps both the airbag and ESP warning lights off
As soon as I switch to “User defined” (needed for Rx), I lose whatever the preset was doing automatically on the Tx side, and I get:
- ESP warning light on permanently
- VCDS: 01314 – Engine Control Module – 004 – No Signal/Communication in the ESP module, persists even after clearing the fault memory
What I’ve rebuilt manually under “User defined” so far (using a DBC I have for this platform):
0x280 (Motor_1): RPM via live channel, byte 2/3, ×4 scale, little endian, 10ms
0x288 (Motor_2): byte 0 tried as both 0x2C (CAN version) and 0x61 (engine code) — no difference either way
Everything else in both messages left at 0 (also tried a plausible coolant temp value, no change)
Does anyone know what the “Volkswagen” preset actually transmits under the hood (which messages/IDs), so I can replicate it fully under “User defined” instead of guessing?
