Nissan Micra Engine Replacement Parts

The engine code is the single most important detail for a used Micra engine, sitting above fuel type, year, or trim level. Common codes across the modern Micra range include the HR12DE and HR12DDT (1.2 petrol), the K9K (1.5 dCi diesel), and the CG10DE, CG13DE, and CR14DE in older K11 and K12 cars, but always verify your exact code from your V5 or a VIN check before approaching a breaker. Supplying the engine code directly to the breaker is the fastest way to confirm you're getting a compatible unit.

Both of those years fall within the K12 generation, which ran from 2003 to 2010, so on the face of it you're working within the same generation. However, Nissan made running changes during the K12's production life, so whether ancillaries, mounts, and engine management systems transfer cleanly across those years is something you should confirm with the breaker against your exact registration. Match the engine code first — if the codes are identical, you're in the best position for a straightforward swap.

Both years sit within the K13 generation, which ran from 2010 to 2017, so they share the same platform and the same engine family. That said, Nissan introduced a facelift for the K13 in 2013, and there can be detail differences in ancillaries or mounts introduced at that point, so confirm specifics with the breaker against your registration. Matching the engine code — typically HR12DE or HR12DDT for the 1.2 — gives you the firmest foundation before anything else.

The K14 is a completely different generation, launched in 2017, built on Renault's CMF-B platform and fitted with different engine families to the K13, so a like-for-like swap between generations is very unlikely to work without significant modification. This is a classic case where the generation boundary matters enormously — name the year and generation clearly when contacting a breaker so they can tell you exactly what's compatible with your K14. Don't assume physical similarity means interchangeability across that 2017 boundary.

For a mechanical part like an engine, trim level makes no difference to fitment — a Visia, Acenta, and Tekna sharing the same engine code will accept the same engine regardless of what's on the badge. Trim does affect cosmetic and comfort features but has no bearing on what sits under the bonnet. Just confirm the engine code, fuel type, and gearbox type with your breaker, and the trim level can be set aside entirely.

If you are buying the bare engine only and keeping your existing gearbox, the donor car's gearbox type usually has no direct effect on the engine block itself. However, some ancillaries — such as the flywheel or flex plate — differ between manual and automatic applications, so check with the breaker exactly what is included in the unit they're supplying. It's worth flagging your gearbox type to the breaker upfront so they can flag any potential differences before the part is dispatched.
