Three-cylinder timing chain, lights and campaigns on the Logan IIKnown weak points
- Engine / equipment
- Dacia Logan II and Logan MCV II (petrol, LPG and diesel)
- Period mentioned
- 2012–2020
- Symptoms
- On the three-cylinders (SCe 75, TCe 90 and 100), a chain that stretches early with a risk of serious failure and sometimes high oil consumption; failing dipped beams, tail lights and indicators, oil leaks, brake discs and suspension at the roadworthiness test; starter, ignition lock and battery.
- Possible cause described
- The naturally aspirated 1.2 16V is far more reliable. Many recalls (KBA): driver airbag (2012–2013 and 2018), track rod (17/9–4/12/2015), front-right caliper, steering-column mounting (23/11/2016–4/1/2018), trailer module, battery (11–14/6/2018) and bonnet latch (2/9/2020–15/1/2021).
- Check for the garage
- Listen to the chain when cold and measure oil consumption; check every campaign by VIN; check lights and leaks before the roadworthiness test.

Applies if: Only with a manual gearbox and built from October 2018 to February 2020.
Creaking when pressing the clutch caused by a non-conforming batch of slave cylindersTransmission
- Engine / equipment
- Dacia models with a manual gearbox
- Period mentioned
- 2018–2020
- Symptoms
- A creak or "crack" every time the clutch pedal is pressed; the gears engage normally.
- Possible cause described
- A non-conforming batch of clutch slave cylinders was fitted from 1/10/2018 to 7/1/2020 (TL4, TL6, TL8 and TLX gearboxes) or up to 10/2/2020 (JH3, JR5 and JXX). The Renault and Dacia technical note reported by L'argus says to replace it with a new part number, after comparing the noise with a recording from the brand. It is not a recall.
- Check for the garage
- Record the noise on your phone while pressing the clutch and show it to the garage, which compares it with the brand's recording before replacing the whole clutch.

Stretched timing chain on the 0.9 and 1.2 TCeTiming system
- Engine / equipment
- 0.9 TCe (H4Bt) and 1.2 TCe (H5Ft) turbo petrol
- Period mentioned
- Approx. 2012–2020
- Symptoms
- Metallic chain rattle, especially when cold or at idle; engine light with a crankshaft–camshaft correlation code; in serious cases the chain jumps and damages the valves.
- Possible cause described
- The chain, meant to last the engine’s life, can stretch early; tensioners and plastic guides wear, and very long oil-change intervals speed up the wear.
- Check for the garage
- With any chain noise or a P0016 code, diagnose straight away: measure the stretch and check the tensioner and guides before the timing jumps. Shorten oil-change intervals.
- Cost cited in the source
- No verified estimate; ask the garage for a quote for the chain kit.A rough figure from the original database, not an up-to-date quote.

Constant whine in the cabin from the 1.5 Blue dCi fuel pumpFuel system
- Engine / equipment
- 1.5 Blue dCi (K9K) in Dacia models
- Period mentioned
- 2018–2019
- Symptoms
- A continuous high-pitched whine inside the car, like a computer fan, that does not change when accelerating.
- Possible cause described
- According to Dacia's note to its dealers reported by L'argus, the noise comes from the fuel pump, whose tank pump-and-sender module was badly designed. The supplier modified it and the new part has been fitted at the factory since 30/9/2019.
- Check for the garage
- Check that the noise does not change with engine speed and ask the garage to listen around the fuel tank before replacing the turbo or the fan.

Applies if: Only the 1.5 Blue dCi built from 1/1/2019 to 31/7/2021.
AdBlue pump damaged by a non-conforming module sealExhaust and emissions (AdBlue)
- Engine / equipment
- 1.5 Blue dCi (K9K) in the Sandero II, Logan II, Duster II, Dokker and Lodgy
- Period mentioned
- 2019–2021
- Symptoms
- Engine and/or AdBlue warning light and a "refill AdBlue, no start in X km" message that keeps appearing even after refilling.
- Possible cause described
- The seal of the urea (AdBlue) pump module does not conform and ends up damaging the pump. It affects cars built from 1/1/2019 to 31/7/2021. Since June 2023, Dacia has run action 0E0K, which replaces the pump and its seal free of charge on cars under 5 years and 200,000 km, but only if the customer complains.
- Check for the garage
- If the warning stays after refilling AdBlue, do not wait for the countdown: ask the dealer for action 0E0K (urea pump and seal) before paying for other AdBlue repairs.

Clogged particulate filter on the 1.5 dCiExhaust and emissions
- Engine / equipment
- 1.5 dCi (K9K) with particulate filter
- Period mentioned
- 2010 onwards
- Symptoms
- Particulate-filter or emissions warning, limp mode with loss of power and frequent regenerations.
- Possible cause described
- The filter clogs, especially on cars that mostly make short town trips and never complete a regeneration.
- Check for the garage
- Read the soot load with a diagnostic tool, run a forced regeneration at the garage and check the differential-pressure sensors and EGR. Make long road trips now and then.
- Cost cited in the source
- No verified estimate; from a regeneration to replacing the filter.A rough figure from the original database, not an up-to-date quote.
