Short answer: the 2.3 dCi engine (M9T) in the Renault Master III, Vauxhall / Opel Movano B and Nissan NV400 comes with two injection systems: Bosch or Siemens VDO (Continental). The injectors are not interchangeable, so identify the make fitted to your vehicle before ordering.
How to tell them apart
| Bosch | Siemens VDO | |
|---|---|---|
| Where to read the number | On the injector body | Engraved on the injector head |
| Manufacturer number | Starts with 0445 (0445110375 or 0445110634) | A2C3335190080 |
| Vehicle maker numbers | 166091245R, 166095586R, 166005070R, 8200912052 | 166000372R, 166093282R |
| Injexo injector | New Bosch 0445110375 | New Siemens VDO 166000372R |
Rule of thumb: if the number starts with 0445, it is a Bosch. If you read 166000372R, 166093282R or A2C3335190080, it is a Siemens VDO.
