Other Faults on This Variant
EGR Valve Carbon Blockage
ModerateEGR 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.
Timing Chain Failure (K9K)
SevereThe 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.
