I installed a flasher on my 2022 Macan GTS 3rd brake. The brake light would flash 2 times but then go dark and create an error message on the dash.
This is called emergency brake light. Can be activated via PIWIS or Launch X431 V+/Pros Mini coding. All rear lights flash when an acceleration (de-acceleration) parameter is met.

The default parameters are when you are doing a speed above 70mph and experience a de acceleration of 0.81G’s, the rear lights (both brake lights and 3rd light) will flash.

I activated in mine and modified parameters so that it activated at any speed above 3 km/h and de-acceleration of 0.71G’s.


For the Macan the setting is in rear end electronics.
Once you turn that option on. Set this option to 1 sec and leave everything this else as is from factory.

I also enabled emergency brake flashing on 991.1, same process as the Macan.
