Is Your Mercedes-Benz Showing These Symptoms?

• Car jerks or bucks during acceleration, especially at partial throttle
• Hesitation followed by a sudden surge of power when accelerating
• Misfire sensation — engine stumbles between 1,500–3,000 RPM
• Rough, uneven power delivery on motorway speed maintenance
• Jerking only when cold — clears after engine reaches operating temperature

Mercedes-Benz Car Jerking on Acceleration — Top Causes

While car jerking on acceleration affects multiple brands, Mercedes-Benz has specific factors that make it worth a specialist diagnosis.

• Misfiring spark plug or ignition coil — most common on petrol cars over 60,000 km
• Dirty or partially clogged fuel injectors reducing spray quality and atomisation
• Faulty mass airflow (MAF) sensor giving the ECU incorrect load data
• Cracked intake manifold or vacuum hose causing lean misfire under load
• Transmission judder mimicking engine misfire — felt through drivetrain not engine

How We Diagnose Car Jerking on Acceleration on Mercedes-Benz

We use Mercedes-Benz XENTRY/DAS (Star C6) to access all Mercedes-Benz modules — engine ECU, transmission control unit, ABS, and body control. This gives us live data and fault codes that generic OBD readers miss on Mercedes-Benz vehicles.

• OBD2 misfire counter scan — identifies which cylinder is misfiring and at what load
• Ignition coil swap test — swap suspect coil with a known-good one to confirm
• Injector balance and fuel pressure test
• MAF sensor live data — g/s reading at idle and 2,000 RPM vs factory specification
