Used Mercedes-Benz M278/M157 exhaust cam/camshaft gear adjuster unit (left side, outlet), OEM part 2780501747. This genuine used part is the variable valve timing adjuster for the exhaust camshaft, controlling cam timing via oil pressure. It also replaces 2780503700, 2780505200, and 2780506400. A failing unit can cause a rattling noise at idle, reduced engine power, or a check engine light for camshaft position correlation. This adjuster is specific to left-side (outlet) installation on the 4.7L M278 and 5.5L M157 twin-turbo V8 engines found in Mercedes-Benz CL, E, G, GL, GLE, GLS, ML, S, and SLK55 AMG models.
