Bulletin Summary
From Mercedes-Benz: Mercedes=Benz is extending the coverage of the exhaust gas recirculation (EGR) valve on vehicle from the vehicle's basic warranty of 5 years/100,000 miles to 15 years/150,000 miles (whichever occurs first) and applies to the vehicle regardless of ownership. Extension is being given because M/B has determined that dimensional variations during engine valve seating may cause the 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
