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.

I have a 2014 audi a6 and an evo one. I downloaded everything and everything went well while programming until the last few steps when the module was flashing red yellow and blue and supposed to turn on and off the ignition I heard the ac turning on and off then the ignition turned off and instead of the LEDs flashing red and yellow it just flashed red and did not read the key
