SummaryExhaust Gas Flap Noise Complaint Customers may report a high-pitched squealing or squeaking noise originating from the exhaust system, specifically near the exhaust gas flap. Cause The noise occurs during actuation of the exhaust gas flap. Internal movement within the flap mechanism, primarily the flap shaft and return spring, can generate friction-induced squeal. Remedy If a squealing noise is present at the exhaust gas flap, do not replace the entire exhaust gas flap assembly or exhaust system. Perform the following corrective action: 1. Confirm the noise originates from the exhaust gas flap actuator area. The squeal typically occurs when the actuator moves the flap during engine operation. 2. Solution: •Remove the Exhaust Gas Flap Controller (AR49.10-D-5507TSM - Remove/install exhaust gas flap controller). •Remove the original spring (Picture 1). •Install the new damping element in place of the spring (Picture 2 and Picture 3). -This damping element absorbs vibration and prevents squealing, eliminating the need for costly component replacements. •Reinstall the Exhaust Gas Flap Controller. •Perform initialization of Exhaust Gas Flap Controller (AD00.00-D-2000-06TS - Connect/disconnect diagnostic unit).

SummaryIn our continuing efforts to assure the proper performance of our products and to ensure the satisfaction of our customers, the warranty for the EGR Valve in the vehicles listed below has been extended from the original 5 years/100,000 miles to 15 years/150,000 miles, whichever occurs first. Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz Sprinter vehicles, has determined that dimensional variations during engine valve seating may cause the exhaust gas recirculation (“EGR”) valve to be switched-off and the vehicle may experience a loss of power and enter a limp home mode. The MIL will illuminate and remain illuminated until the vehicle is serviced. When this occurs, the driver may perceive a jerky driving experience while operating the vehicle. An authorized Mercedes-Benz Sprinter dealer will clean and/or replace the EGR valve free of charge for the customer.
