What are the signs of a clogged fuel filter in a Mercedes-Benz E-Class, and how does it affect engine performance?

My Mercedes-Benz E-Class is showing reduced engine power and hesitation during acceleration. Could a clogged fuel filter be the reason? How common is fuel filter clogging in Pakistan, and what maintenance should be done to prevent it?

A clogged fuel filter restricts the flow of fuel to the engine, causing various performance issues:

Reduced engine power and sluggish acceleration.

Engine hesitation o r stumbling during acceleration.

Difficulty starting the engine o r rough idling.

Possible engine misfires o r stalling under load.

In Pakistan, due to variable fuel quality and impurities, fuel filter clogging can be relatively common. Regular maintenance and timely fuel filter replacement are essential to maintain smooth engine operation and prevent damage to fuel injectors.
