A Mercedes Benz 350L arrived for diagnosis of misfiring and engine stalling issues.

If your car is misfiring, jerking or engine keeps stalling, these symptoms are pointing to a faulty ECU (Engine Control Unit).

An illuminated Check Engine light is another possible symptom your car has developed a problem with the ECU when the computer detects a fault with any of its sensors or circuits. The symptoms may not appear to have any sort of pattern to their frequency or severity.

The ECU controls a series of actuators in the engine to ensure optimum engine performance.  It functions as the main computer for the vehicle’s engine performance.  The ECU has a huge impact on your car’s operation as takes the information from the engine’s sensors and uses the information to calculate and tune engine sparks and fuel for maximum power and efficiency.

A customer drove his Mercedes S350L to Revol Carz Garage having encountered an engine misfiring symptom.  Our team of professional mechanics diagnosed a faulty ECU module.

The issue was promptly resolved with replacement of an original ECU.

Alas! The brand new ECU is successfully installed and the Mercedes runs like new again.
