Passat 3C Cold Start Diagnosis LED Lights

28-04-2012, 21:04 Subject: Passat 3C Cold Start Diagnosis LED Lights

Hi everyone,

I was just trying to drive my Passat 3C, manufactured in 09, and then I heard the comment "Nice disco!"...

I have ALL cold diagnoses activated, while a comparable Passat only has brake lights, turn signals, side markers, and parking lights activated.

If I disable the central "active cold diagnosis" (= it's no longer a diagnosis), then it stops flashing.

"But I haven't been able to see this behavior in any other car - is my control unit simply incorrectly coded?" Does a cold diagnosis even help with LEDs?

Best regards,

Marco

Hello,

I assume that no errors are currently being detected in the lights.

Does a cold diagnosis with LEDs actually achieve anything?

If, for example, you disconnect the taillight connector and then a warning message appears in the dashboard: Yes

Best regards, Rainer

... but the disco is clearly visible from inside (brake light) and from outside (rear/stand light).

What is your BNSTG?

I want to go to the disco too

Cool, that CC unit with a heatable windshield.

Let's see what my 3C8-E has to say about the disco.
