Bosch 0445120043 Common Rail Injector (0 445 120 043) | OEM MWM 961204640014 / VW 2R0130201B – CRIN Injector With Exchange 0986435541

A common-rail injector is not a "fuel part" in the old mechanical sense-it's a precision valve that decides combustion quality thousands of times per minute. If you're searching 0445120043, you're usually trying to solve one of three field problems: hard starting, unstable idle, or smoke/power inconsistency under load. The Bosch 0445120043 (Bosch No. 0 445 120 043) is a CRIN-family common rail injector widely cross-referenced to MWM and VW industrial/commercial applications, and it is frequently sold alongside a Bosch exchange/reman reference and matching nozzle information used by workshops for correct rebuild work.

Bosch injector number: 0445120043 / 0 445 120 043

Bosch exchange / reman reference: 0 986 435 541 / 0986435541

OEM references commonly shown:

MWM: 961204640014 (also shown as 9 6120 46 4 0014)

MWM: 107755-0200

VW: 2R0130201B / 2R0 130 201 B

If a customer comes in with "961204640014 injector" or "2R0130201B injector", the goal is to land them confidently on 0445120043.

 

Many diesel parts catalogs and retailers position 0 445 120 043 for MWM and VW-linked platforms (industrial or commercial variants), and some sellers explicitly market it for Volkswagen commercial chassis/bus families.
Because fitment tables can differ by region and catalog, the best practice is always: match Bosch number + OEM cross-ref rather than relying on a generic "fits" list.

 

Buyers often assume all injectors are interchangeable if the engine "runs." Common rail doesn't work that way. The 0445120043 is frequently labeled as a CRIN injector, and even third-party catalogs tie it to specific internal families (e.g., CRIN identifiers and cross-compatibility notes).

That matters because failure symptoms can be misleading:

A worn injector can imitate a weak high-pressure pump (slow rail build, extended cranking).

Poor atomization can look like a turbo/EGR issue (smoke under load).

Return-flow imbalance can feel like "random misfire" in a diesel (rough idle).

Replacing the correct injector restores repeatability-consistent delivery, clean burn, and stable response-so the ECU and rail system can operate within their expected control range.

 

 

For rebuilders and technical buyers, the nozzle reference is often part of the search intent. Many listings associate 0445120043 with nozzle stampings such as DLLA143P1404, and nozzle part numbers like 0433171870 are published in specialist nozzle pages.

You'll also see cross-compatibility claims in catalogs that list a "compatible part number" such as 0445120326 alongside 0445120043. Treat this as a catalog family hint, not automatic substitution-always confirm your exact OE cross-reference and injector marking.

 

Online results commonly show:

New injector listings under 0 445 120 043 / 0445120043 (often sold as single units or in sets)

Exchange/reman references under 0 986 435 541 / 0986435541, which is frequently tied to this injector number in catalogs.

For fleet buyers, the low-risk procurement description should clearly state:
✅ Bosch number, ✅ OEM cross-refs, ✅ whether new or exchange/reman, ✅ warranty/core policy (if applicable).
