Mercedes R Klasse Diesel Injection Issue

The symptoms you describe certainly point towards a potential issue with the fuel injection system Increased fuel consumption reduced power stalling and smoke are all common indicators A defective cable or plug connection affecting a component is a plausible cause I recommend a diagnostic check to confirm The fuel injection system is responsible for delivering fuel to the engine A malfunction in this system can drastically affect performance and fuel efficiency

Thanks for the quick reply What exactly does a 'diagnostic check' involve Is this something I can do myself or is specialized equipment required

A diagnostic check involves using specialized equipment to read error codes stored in your vehicle's engine control unit ECU The ECU is a computer that monitors and controls various aspects of the engine's operation including the fuel injection system While some basic OBD2 scanners are available for home use a professional-grade scanner can provide more detailed information Considering the symptoms I recommend taking your R Klasse to a qualified workshop for a thorough diagnosis A damaged fuel injection system can have a serious impact on the operation of your Diesel engine

Understood I took it to a local mechanic You were spot on it was a faulty plug connection in the injection system The repair cost 95€ Thanks for the advice
