Sport Exhaust System (I-no. XLF/XLX)
Concern:
Retrofitting
Model Year:
As of 2017
Engine Types:
MA220 = 2.0 l
MA222 = 2.5 l
Notes:
The sport exhaust system can be activated/deactivated by pressing the button with the "Twin tailpipe"
symbol.
The sport exhaust system is also active in "Sport" or "SportPlus" mode. Here, the sports exhaust system
can be switched off or even switched on again using the "Twin tailpipe" button.
The switch console (combined switch) is a repair kit and must also be ordered. The repair kit contains the
main body, the required buttons and the trims. The new switch console is assembled in accordance with
the new vehicle equipment.
Engine power and exhaust behaviour of the vehicle are not affected. The sports exhaust system is also
available ex-works for new vehicles by requesting optional equipment XLF or XLX.
