Complaint

The vehicle exhibits an acoustic feedback of the exhaust system under the following conditions:

^ Engine braking in 1st, 2nd or 3rd gear

^ Increasing engine speed above 3000RPM while vehicle is stationary

The popping noise from the exhaust system can also be described as a "backfire" from the engine.

Measure

Do not attempt to repair or replace any parts, this is not a failure of any driveline components.

The acoustic feedback is a standard feature of the 2005 Model Year Cooper S vehicle produced as of 7/2004. This feature cannot be retrofitted to the previous model year vehicles.
