Known Faults

Timing Chain Failure (K9K)

Severe

2009-201680,000–150,000 miles£600–£1000

The K9K timing chain issue is widespread across the Renault range and the Scenic Mk3 is no exception. Chain wear leads to rattling and ultimately engine failure.

EGR Valve Carbon Blockage

Moderate

2009-201650,000–100,000 miles£100–£400

EGR failure on the Scenic Mk3 follows the K9K pattern — carbon accumulation causes power loss and rough running, compounded by the MPV's urban use profile.

DPF Blockage from Family Use

Moderate

2009-201640,000–90,000 miles£200–£900

The Scenic Mk3 dCi is the family diesel MPV — used for exactly the kind of short school-run trips that block DPFs. It is by far the most common fault reported by Scenic owners.

Electric Sliding Door Motor Failure

Minor

2009-201660,000–140,000 miles£150–£600

The Scenic Mk3's powered sliding rear doors develop motor faults, leaving the door either stuck open or requiring manual operation. A unique fault to the MPV body style.
