2017 Audi A6 2.0 TDI EVO-ONE: no crank unless brake pressed (guide 79791)

Mon, 19 Oct 2026 13:48:28 +0000

Hello Fortin Support,

I need help verifying the brake activation and CAN1 wiring for an EVO-ONE installed in a 2017 Audi A6 C7.5 2.0 TDI, right-hand drive, automatic, push-to-start.

Installation guide: #79791

Bypass firmware: 60.12

Remote starter firmware: 1.31

DCryptor completed successfully.

Symptoms:

- Pressing lock three times on the OEM remote triggers the ignition, but the engine will not crank unless I physically press the brake pedal.

- The brake lights do not illuminate during the remote-start sequence when the pedal is not pressed.

- If I hold the brake pedal, the engine starts but shuts off after approximately 2 seconds.

Current connections:

- EVO-ONE D2 Yellow/Blue is connected to the vehicle Red/Black brake circuit.

- CAN1 is tapped into the Orange/Green and Orange/Brown twisted pair at the brown 16-pin BCM connector C. The Fortin guide shows a black connector, so I would like to confirm whether my connection point is correct for this RHD C7.5 vehicle.

Could you please verify:

1. The correct brake activation signal for this exact vehicle: connector and pin, wire colour, required polarity/voltage, and whether D2 Yellow/Blue should connect directly to the Red/Black circuit or requires a different interface. Is this the correct signal to satisfy the push-to-start brake requirement?

2. The correct CAN1 High/Low connection point, connector and pin numbers for the RHD C7.5, including whether the brown 16-pin BCM C Orange/Green and Orange/Brown pair is correct despite the black connector shown in guide #79791.

3. The recommended fix and any required firmware or option changes for the no-crank condition and 2-second shutdown.

Thank you.
