Starter motor, brakes, suspension and rust on the Scénic IIIKnown weak points

Engine / equipment: Renault Scénic III and Grand Scénic III (petrol and diesel)
Period mentioned: 2009–2016
Symptoms: A failing starter (especially 2009–2010), worn or cracked brake discs from the seventh year, broken springs, joints and steering at the roadworthiness test, rusty underbody after about five years, failing exhaust and lights; on diesels, the boost-pressure sensor.
Possible cause described: TÜV data collected by the guide. Recalls: untightened seat-runner bolts, a vacuum pump that could remove brake assistance, injection software for low manifold vacuum and automatic-gearbox software.
Check for the garage: Check the campaigns by VIN (vacuum pump, seats); check discs, springs, joints and underbody.
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.

1.5 dCi timing belt or pulley failureValve timing

Engine / equipment: 1.5 dCi (K9K)
Period mentioned: 2009–2011
Symptoms: Noise or squeal around the belts; if the timing belt breaks, the engine stops suddenly and can be badly damaged.
Possible cause described: On 2009–2011 engines, pulleys and timing or auxiliary belts were reported to break.
Check for the garage: Keep to the timing-belt interval and always replace the full kit (belt, rollers and pulleys); check the auxiliary belt and its pulley.
Cost cited in the source: No verified estimate; ask the garage for a timing-kit 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.
