Auto Hold Hill Start Assist for Audi A6 C8 A7 Q7 Q8 4M

Auto Hold Hill Start Assist Retrofit Kit For Audi A6 C8 A7 Q7 Q8 4M

Many Audi A6 C8, A7 4K, Q7 4M, and Q8 4M models are equipped with an electronic parking brake but may not include the convenient Auto Hold function from the factory.

This Audi Auto Hold Retrofit Kit allows you to add the original-style automatic brake holding function without replacing the complete brake system. By installing the Auto Hold switch module and connecting the dedicated wiring harness, the vehicle can activate the Auto Hold feature through professional coding.

Once activated, the system automatically holds the brake pressure when the vehicle comes to a complete stop. The driver can release the brake pedal while waiting at traffic lights, in traffic jams, or when stopping on an incline.

Compared with aftermarket universal solutions, this retrofit provides a cleaner OEM appearance and integrates with Audi’s original electronic parking brake system, delivering a factory-level upgrade experience.

The Auto Hold function improves everyday driving comfort, reduces foot fatigue, and provides additional convenience during urban driving and hill starts.
