Model Year:
As of 2009
INFORMATION:
Retrofitting
Restriction:
Not approved for vehicles with power kit (I-no. X51).
NOTES:
In the sports exhaust system, the signal for activating the flaps in the rear mufflers comes from the respective current map in the DME control unit.
This depends on the driving status and the accelerator pedal position among other things.
The sports exhaust system is activated and deactivated using the new switch console with additional "Double tailpipe" button.
If the diodes in the "Double tailpipe" button light up, the sports exhaust system is active (exhaust motor can be heard).
The regulating time after pressing the button, determined by the response time of the pneumatics, is approx. 1 - 2 seconds.
Engine power and exhaust behaviour of the vehicle are not affected.
