Summary
Mercedes-Benz AG (âMBAGâ), the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2018-2023 C-Class, EQE, EQE SUV, EQS, EQS SUV, GLC, GLE and S-Class (206, 295, 294, 297, 296, 254, 167 and 223 platform) vehicles, the communication module software does not correspond with the latest series production configuration. The update is free of charge and will be carried out in the background. The installation will eliminate software errors for a better entertainment experience. The update will show after the ignition has been cycled. MBUSA will conduct an OTA service campaign. A workshop visit for the customer is not required since remote software updates are automatically downloaded and installed in the customerâs vehicle. The OTA may be validated as successful on the customerâs Mercedes Me connect app under âOver-the-Air Vehicle Updatesâ as âUpdate for the communication moduleâ. If the OTA is successful it will show a green âinstalledâ and date of installation in the Over-the-Air update section.

Summary
In our continuing efforts to assure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA, LLC (âMBUSAâ) is extending the warranty coverage on the exhaust valve system in certain Model Year (âMYâ) vehicles listed below from the original New Vehicle Limited Warranty of 4 years/50,000 miles to 15 years/150,000 miles (whichever occurs first). 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). â¢ 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 (âMILâ). 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. â¢ P030085 â Combustion misfire has been detected â¢ P030x85 â Cylinder x misfire detected. (x = the affected cylinder) â¢ P1CEF85 - Injector injection quantity adjustment for cylinder balancing has almost reached the upper limit value at atleast one cylinder. â¢ 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: â¢ 01201 â Cylinder Head â¢ 05202 â Exhaust Valve â¢ 01205 â Valve seat ring exhaust valve â¢ 01206 â Valve Guide Exhaust Valve

Summary
Complaint Customer may complain of a CEL on in the instrument cluster, rough running, trouble starting, issues with ECO stop/ start or a combination thereof. Cause One or more broken valve springs in the cylinder head. Remedy Work through the guided tests for any relevant fault codes. For misfire related fault codes this will include: â¢ Inspecting the injector performance data for abnormalities â¢ Using a smoke machine to inspect for air leaks â¢ Performing a compression and leakage test Depending on the severity of the failure, a broken valve springs may be able to be found in a compression/leakage test. If not it may also show up on a PICO running compression test. To verify the best method is to remove the cylinder head cover and inspect the valve springs directly If a broken valve spring is found: â¢ Inspect the valve, rocker, retainer, and keepers on that assembly for damage. â¢ Inspect the camshaft and camshaft lobe that operates that valve â¢ Inspect the piston face via borescope for piston/valve contact Also perform a leak test once the valve is able to be fully seated to ensure no damage to the valve or seat has occurred. If no damage to the piston or valve seat has occurred, replaced the damaged components and release the vehicle. If valve seat or piston damage has occurred please open a PTSS case, upload the results of all tests, and outline what work has been conducted thus far.
