A6 4F: Install Horn DWA System

Hi.

Yesterday, I wanted to make an Audi A6 4F honk its horn so that the owner would know when the car was locked or unlocked.

The Comfort STG was copied 133 times, so:

1 + 4 + 128

He didn't eat the 2048, probably because the DWA (16) wasn't encoded.
He does!

Should then.
Is this the solution: 1 + 4 + 16 + 128 + 2048?

I see it that way too.
It might also be worth investigating whether he uses the IRUE and NGS systems.

Sure, Maxx.

IRÜ and NGS are not that relevant; the vehicle's immobilizer system (DWA) generally functions without them, relying on the door contacts and immobilizer. However, the real question is: is the DWA system, including the DWA siren, actually installed?

You're right about that, Sebastian.
My comment was only intended as additional information.
It is clear that the DWA (water treatment plant) should also function without the two sensors.

SG, Maxx.

"Do you have any tips on how to ensure proper installation of plumbing fixtures?"

I would do the following:

1.) Encode your solution.
2.) Open the hood.
3.) All doors and the tailgate will close.
4.) Lock the vehicle.
5.) Use a screwdriver to press the microswitches located on the hood lock mechanism.
6.) After a few seconds, release the button again.

If a water leak detection system (DWA) is installed, the vehicle should sound a horn or buzzer.
