Suspension, oil leaks and campaigns on the Scénic IVKnown weak points

Engine / equipment: Renault Scénic IV and Grand Scénic IV (petrol and diesel)
Period mentioned: 2016–2022
Symptoms: Suspension defects well above average at the first roadworthiness test, lights, misaligned doors and interior rattles, engine and gearbox oil leaks after a few years and timing chains that may need replacing before 100,000 km.
Possible cause described: Recalls: automatic-gearbox console insulation (DW5/DW6) that could release P, curtain airbags, cooling-fan capacitors on manual 1.5 dCi (K9K) and 1.7 (R9N), and an R9N fuel line that could leak.
Check for the garage: Check every campaign by VIN; check the suspension, oil leaks and chain noise when cold.
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.

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.
