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.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

Engines: 0.9 TCe (H4Bt) (Petrol)

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.

Engines: 1.5 dCi (K9K) (Diesel)

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.
