Car Alarm System for Audi A6 C4

Hello TDI community,

I have an A6 C4 TDI and I want to install the Waeco remote control for the central locking system. There's the MT150 model available for Audis with and without the alarm system (DWA). How can I find out if my Audi has the alarm system or not?

Thank you in advance.

Regards,
Michael.

As with any DWA (German water and wastewater association) event: Simulate a breakdown!

Lower the window, properly lock the vehicle (using the remote control or with the key), then wait for a defined amount of time (at least 30 seconds, preferably a full minute), and then unlock the vehicle from the inside through the window (do not use the key from the outside, but unlock it from the inside).

Then open the door. If the DWA starts, then you have one, otherwise not .

Hi,

"If you activate the alarm system, the indicator light for the rear window defroster (or another indicator) will start flashing red rapidly several times in a row, and then it will flash red every 5-10 seconds. Additionally, locking the vehicle will be acknowledged by a horn sound (at least, that's how it works in my mother's 1994 Audi 100 C4, which is also where I installed the MT150)."

Best regards,
Munch.
