R/2018/20624 Aug 2018Built 2010–2016Oil foam may develop in the active curve system oil reservoir

It has been determined that on Model series ML/GLE GL/GLS (166) & GLE Coupe (292) with ACTIVE CURVE SYSTEM (ACS) Oil foam may develop in the systems oil reservoir under dynamic operating conditions and at an oil level below the minimum level and escape via the ventilation bores in the cap of the reservoir. Depending on the orientation of the two ventilation bores the escaping oil could spray onto hot component parts of the exhaust system. In this case risk of fire cannot be ruled out.

Fix: On affected vehicles replace the oil dipstick of the reservoir for the ACTIVE CURVE SYSTEM.
