Other Faults on This Variant

Timing Chain Failure (K9K)

Severe

2006-201380,000–140,000 miles£500–£900

The Note E11 uses the same K9K 1.5 dCi as the Qashqai, Juke and Clio. The timing chain tensioner wear is identical — rattle must not be ignored.

DPF Blockage

Moderate

The Note is frequently used as a family runabout on short trips — the worst use case for a diesel with a DPF. Blockage is the most common fault on diesel Notes.
