Component

Engine and engine cooling: exhaust system: emission control: gas recirculation valve (EGR valve)

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.
