This extended warranty applies to the condition described below that may necessitate the repair or replacement of components related to the exhaust valve assembly (e.g. exhaust valve, cylinder head). • The valve guide and/or seat ring may wear over time due to increased lateral forces during operation. This could potentially cause combustion misfire for cylinder 1 through 4, resulting in an activation of the check engine Malfunction Indicator Lamp (“MIL”). Please be advised that all repairs being claimed under this extended warranty must have a Quick Test uploaded with the following fault code information, and may be audited. • P030085 – Combustion misfire has been detected • P030x85 – Cylinder x misfire detected. (x = the affected cylinder) • P1CEF85 - Injector injection quantity adjustment for cylinder balancing has almost reached the upper limit value at atleast one cylinder. • P1CE577 - Injector injection quantity adjustment for uniform mixture formation has detected an excessively lean mixture at atleast one cylinder. All repairs found to be functioning properly or without proper documentation will be returned and the claim debited in full. Only the following damage codes and parts may be claimed for the aforementioned repairs: Damage Codes: • 01201 – Cylinder Head • 05202 – Exhaust Valve • 01205 – Valve seat ring exhaust valve • 01206 – Valve Guide Exhaust Valve

  Summary

  Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2020-2021 GLA-Class and GLB-Class (156/247 platform) vehicles, the transmission bearing cap cover does not correspond to current specifications. Over time, the transmission bearing cover may loosen, which may result in minor oil loss. An instrument cluster transmission light will still alert the user if it falls below the threshold and alert the driver if the transmission oil overheated. The indicator light will alert the driver to drive with caution. A risk of fire can be ruled out. What We’re Doing MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will replace the transmission bearing cover.
