This technical information replaces bulletin Group 2, # 4/07, dated March 27, 2007.
Information:
Retrofitting
Model Year:
As of 2007 up to 2008
Engine Types:
M97/20 = 2.7 liter and M97/21 = 3.4 liter
Note:
In the sport 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.
Sport exhaust system control:
^ Vehicles with Sport Chrono package (I-nos. 639/640): --> Switch console with "Sport" button (see Owner's Manual for the vehicle)
^ Vehicles without Sport Chrono package: --> New switch console with additional 'Twin tailpipe" button
The activation time after pressing the button, determined by the response time of the pneumatics, is approx. 2 - 3 seconds. If the diode in the "Sport" (I-nos. 639/640) and "Twin tailpipe" buttons lights up, the sport exhaust system is active.
Engine power and exhaust behavior of the vehicle are not affected. The sport exhaust system is also available as a factory installed option for new vehicles by requesting optional equipment "XLF".
