Mercedes-Benz E-Class vehicles in Pakistan sometimes face engine performance issues such as rough idling, reduced acceleration, overheating, and increased fuel consumption. These problems can be caused by several factors including poor fuel quality, clogged fuel injectors, malfunctioning sensors like MAF o r oxygen sensors, and inadequate engine cooling due to dusty conditions o r radiator clogging. Additionally, inconsistent maintenance o r delayed servicing exacerbates these issues. To improve performance and fuel efficiency, owners should use high-quality fuel, regularly clean o r replace air and fuel filters, and ensure the cooling system is functioning properly. Regular engine diagnostics and timely replacement of worn components help maintain optimal engine health. Some owners also benefit from ECU tuning to adapt to local fuel quality and driving conditions.
