Adaptive Headlights: Improve Night Driving Safety (Weblog JettaJens)

Translated on 03-08-2026, 7:26.

Hi,

I have already successfully installed headlights from an Audi A4, including the turn signal lights, into my VW Passat 3B.

However, the headlights also feature adjustable lenses for adaptive cornering lights.
So, my plan now is to get the cornering lights working.
Based on my research so far, I need the values from the steering angle sensor and the speed sensor.
That's how I came across this forum, and I hope to get some information on how I can read the values continuously during driving and then process them further.

Thank you.

Hello,

Welcome.

You should find both of these values on the engine CAN bus, as they are required for the ABS system.

Best regards, Rainer.
