Engine stalling o r hesitation in the S-Class often happens due to a combination of factors:

Faulty Sensors: Components like the Mass Air Flow MAF sensor, throttle position sensor, o r crankshaft position sensor can malfunction, sending incorrect data to the ECU and causing hesitation o r stalling.

Fuel Quality: In Pakistan, inconsistent fuel quality o r adulteration can cause poor combustion, leading to engine hesitation o r stalling.

Fuel Delivery Issues: Clogged fuel injectors, dirty fuel filters, o r weak fuel pumps reduce fuel supply to the engine.

Ignition System Problems: Faulty spark plugs o r ignition coils can cause misfires, resulting in hesitation o r rough idling.

Dust and Climate: Harsh road and weather conditions add stress to engine components, increasing the chances of these issues.

Regular maintenance, using quality fuel, and prompt sensor replacements can reduce these problems significantly.
