Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain
subject vehicles, the engine control unit software does not correspond to current production
specifications. The diagnosis routine for the pressure sensor in the crankcase ventilation system may
be populated with incorrect data. As a consequence, the check engine light may illuminate after the
Issue
engine is switched off even though there is no functional impairment.

Remedy

MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the engine
control unit software.

Launch Date Affected VINs will be flagged as “OPEN” in VMI on Thursday, April 17, 2025.
Warranty Claim Notice

Please note the campaign will close after the warranty claim has been submitted. This change can
take at least one-day to reflect in NetStar VMI.

While we regret any inconvenience this may cause, MBUSA is determined to maintain a high level of vehicle quality and
customer satisfaction. Please refer all customer inquiries to the Customer Care Center at 1-800-FOR-MERCEDES.
