Each injector sits deep in the head on a copper sealing washer, and that washer is the R9M 402’s weak point. When it gives way, combustion pressure chuffs up the injector bore on every power stroke: a ticking or chuffing under load that gets louder as the seal degrades, and a ring of black carbon around the base of the injector where the gas has been escaping. Left alone, the escaping gas erodes the bore itself, which turns a seal replacement into machining work – and on an engine with four injectors, the failure rarely stops at one.
The chuff is only the beginning. Escaping gas contaminates everything around the injector wells, the engine management compensates and runs rough, and fuel economy slides. On engines that continue in service, the timing chain stretches with mileage and adds a rattle at the timing-case end on idle. The EGR system and intake ports coke up on town-driven cars, throttling low-rev response, and the DPF – already struggling without motorway runs – blocks sooner. By the time two or three of these overlap, piecemeal repairs cost more than a matched replacement with a warranty.

Every engine match is confirmed against your registration before any quote is issued, and all work is carried out by vetted third-party workshops operating as an independent comparison service.
1. A ticking or chuffing under load, strongest on a cold engine, tracking with throttle. 2. Carbon build-up visible around the injector seats on removal of the covers. 3. Rough idle and a drop in fuel economy as the gas leaks confuse the combustion. 4. A rattle from the timing end at idle as the chain wears with mileage. 5. EGR flow faults and a dulled throttle on town-heavy cars, with DPF warnings not far behind.
The R9M 402 shares its architecture with the R9M 410 – the van-calibrated version in the NV300 – and sits alongside the R9N 401 that Nissan used elsewhere. Outputs, services and even some internals differ between them, so a replacement must be matched to the exact code on your block, not to the family resemblance. Your registration settles the question in seconds, and the workshop confirms the stamp before anything is sourced.
Choose how you want your R9M 402 supplied: reconditioned to spec, a tested low-mileage used engine, or a complete supply & fit package with recovery.

A single chuffing injector on a otherwise healthy engine can sometimes be resealed successfully – and a competent workshop will say so honestly. The case for replacement grows when the bores are eroded, when a second injector starts chuffing, or when the chain and EGR side are worn with it, because each separate repair means paying for the same engine access again. On a Qashqai or X-Trail with sound bodywork and history, one matched engine with fresh seals, chain and rings is usually the cleaner financial answer.
Fitting a R9M 402 engine means confirming the emissions hardware is clear before the engine goes in, so the replacement is not immediately restricted. The network workshops handle the changeover with new fluids and filters, and every installation is warranty-backed.
You submit the registration, the workshop verifies the R9M 402 stamp, and a reconditioned or tested used engine is sourced to that exact code. Your injectors are inspected and resealed or replaced, the EGR side is cleaned, fresh belts and fluids go in, and the car is road-tested and returned with a 6 to 12 month warranty. Most jobs complete within two to three working days of the engine arriving, with recovery available for cars that will not make the trip.
