Electrical issues are quite common in Mercedes-Benz E-Class cars in Pakistan due to a combination of aging vehicles, climate factors, and sometimes inconsistent maintenance. The most frequent problems include malfunctioning dashboard displays, erratic warning lights, faulty sensors like oxygen sensors o r wheel speed sensors, and power window o r central locking failures. These issues often stem from poor grounding, corroded connectors, o r damaged wiring harnesses caused by moisture and dust ingress. Local mechanics typically diagnose these problems using specialized diagnostic tools like the Mercedes Star Diagnostic system, and repairs may involve cleaning o r replacing connectors, rewiring, o r replacing faulty sensors. Owners are advised to keep the electrical system dry and regularly inspect wiring, especially after monsoon season.
