Manual gearbox, suspension, turbo and oil consumption on the Laguna IIIKnown weak points

Engine / equipment: Renault Laguna III (petrol, dCi and V6)
Period mentioned: 2007–2015
Symptoms: A manual gearbox (PK5/PK6) whose bearings fail, sometimes from 20,000 km; worn bushes and track-rod ends; brake discs that wear early; broken springs; turbo damage on diesels (more on the 1.5 dCi); high oil consumption on the 2.0 16V (M4R); poor fit of doors, bonnet and trim. The 3.0 dCi V6 is the most fragile engine and the V6s are expensive to repair.
Possible cause described: According to Honest John, PK gearboxes leave the factory with the bearing preload too tight; once replaced and correctly shimmed they last. The turbo suffers from not warming up or cooling down the engine and from late oil changes. Recall: seat belts (built 1/1/2007 to 24/8/2009). CarWiki rates the four-cylinder engines as reliable.
Check for the garage: Listen for gearbox whine in every gear; check suspension and brakes; measure oil consumption; check the campaign by VIN.

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.
