Mercedes-Benz W212 E-Class Facelift Full LED Intelligent Light System Headlight Assembly (Right Side) - Used Original Parts

Diagnosis and Common Symptoms

When diagnosing the Mercedes-Benz W212 E-Class Facelift, the Full LED Intelligent Light System (ILS) is a highly advanced component prone to specific electronic and physical failures. A common issue is the degradation of the Daytime Running Light (DRL) light tubes, which often turn yellow or burn out entirely due to overheating at the LED diode or failure of the DRL voltage control module. Additionally, compromised seals can lead to water ingress, destroying the main LED driver modules mounted to the bottom of the housing. Drivers will typically see an "Intelligent Light System Inoperative" or "Active Headlamps Inoperative" message on the instrument cluster. Diagnostic scans using Xentry may reveal fault codes such as B16E0 (DRL control module fault), U025A (Lost communication with headlamp control module), or stepper motor faults related to the dynamic curve illumination failing to initialize during start-up.
