A Check Engine Light (“CEL”) can illuminate for a number of reasons. Authorized Mercedes-Benz Sprinter Dealers will diagnose the vehicle and repair the vehicle at the Owner’s/Lessee’s discretion. Issues that arise in the vehicle prior to the Emission Modification (“EM”) being approved and ready for installation on the vehicle, including affected components which would be replaced as part of the EM, are the responsibility of the Owner/Lessee.
Once the EM is approved and ready for installation on an eligible vehicle, certain components will be installed to update the emission system in the vehicle. Should a vehicle exhibit a CEL prior to EM installation, an authorized Mercedes-Benz Dealer will advise the Owner/Lessee if additional repairs will be needed to ensure the proper functioning of the vehicle’s emission system. Depending on the faulty component, these repairs may be the responsibility of the Owner/Lessee.
