Jerking on Dacia: causes by model and engine

Documented faults, from most to least important

Severity × frequency. Below each one, the Dacia models it appears in.

- Critical severityFrequency: Common1.2 TCeExcessive oil consumption and engine failure1.2 TCe and 1.2 DIG-T engines built from 2012 to mid-2016 can burn more than 1 litre of oil per 1,000 km because the piston rings do not seal properly; carbon damages the valves and the engine can fail. There was no recall: the dealer network reprograms and replaces rings or the engine.Repair: €5,000–€10,000
In Dokker, Duster I and Lodgy
- Critical severityFrequency: Occasional1.0 TCe / SCeLPG (ECO-G) system faults and tank recallThe ECO-G (LPG) version of the 1.0 TCe can show erratic switching between petrol and gas, gas injection faults or an inaccurate level gauge. In addition, Renault and Dacia recalled part of the 2023 production over a risk of leaks and fire from the tank.
In Jogger, Logan III and Sandero III
- Medium severityFrequency: Common1.2 16vIgnition coil failure (misfires, engine warning light)The ignition coil is the engine fault that recurs most on the 1.2 16v: it appears independently on the Renault Clio II and Clio III, with misfires, jerking or the engine warning light coming on.
In Logan I, Logan II, Sandero I and Sandero II
- Medium severityFrequency: Occasional1.5 dCiInjector and injector seal failuresThe 1.5 dCi injectors, or their seals, can fail early, especially on the 110 hp, causing rough running, jerking or hard starting. Replacing the affected injector is usually enough; Caradisiac still reports cases on the Kadjar and Duster II.
In Dokker, Duster I, Duster II, Lodgy, Logan I and Logan II and 2 more models
- Medium severityFrequency: Occasional1.4 and 1.6 8vIgnition coil failureThe ignition coils fail in a minority of reports for the Clio II and the Dacia Sandero I with this engine, in a considerably smaller proportion than on the 16-valve evolution of the same block. They cause jerking and the engine warning light, but do not damage the engine.
In Logan I and Sandero I
- Medium severityFrequency: Occasional1.0 SCe (B4D)Jerking, rough idle or warning light from sensors and ignition coilsThe 1.0 SCe can jerk, run unevenly or light up the engine fault warning light because of sensor faults (lambda sensor), ignition coils or injection management. It is a recurring but minority issue in the sources consulted, unrelated to a mechanical problem with the engine block.
In Logan II and Sandero II
- Low severityFrequency: Rare0.9 TCeJerking due to an injection calibration that needs reprogrammingSome 0.9 TCe engines show slight jerking when accelerating because of an injection calibration that is corrected by reprogramming the ECU, without it being mechanical damage.
In Logan II and Sandero II

Jerking in a Dacia: what could it be?

In 11 models from Dacia there are 7 documented faults that cause this symptom (jerking). The most important: excessive oil consumption and engine failure, LPG (ECO-G) system faults and tank recall and ignition coil failure (misfires, engine warning light). Each fault has its own page with the affected years and versions, the cause and how to check for it.

Which Dacia models have the most faults with this symptom?

Dacia Logan II (4 faults), Dacia Sandero II (4 faults), Dacia Logan I (3 faults) and Dacia Sandero I (3 faults).

Which Dacia engines cause it?

0.9 TCe (1 fault), 1.0 SCe (B4D) (1 fault), 1.0 TCe / SCe (1 fault), 1.2 16v (1 fault) and 1.2 TCe (1 fault).
