The Bosch injector part number 0445120162 is a common-rail diesel injector, typically a solenoid-type unit used in various European and Asian applications. However, when it comes to the Volkswagen Worker 3.2 (2012) — a heavy‑duty truck model sold mainly in Brazil and Latin America — compatibility is not straightforward. Below I’ll break down what this injector is normally used for and how to confirm if it suits your vehicle.
Typical Applications of Bosch 0445120162
This injector is most often found in 2.0 TDI engines from the Volkswagen Group (VW, Audi, SEAT, Škoda) with engine codes such as:
CBAB, CBBB, CFGB, CFFB (common in VW Amarok, Passat, Tiguan, etc.)
Audi A3, A4, A6 2.0 TDI
Škoda Octavia, Superb 2.0 TDI
It is a solenoid injector (not piezo) with a nominal flow rate suited for engines in the 100–140 kW range.
It is not originally intended for a 3.2‑litre diesel truck engine.
Volkswagen Worker 3.2 (2012) – Engine Reality
The Volkswagen Worker is a medium‑duty truck series. The Worker 3.2 from that era is powered by a MWM 4.12 TCE engine, a 3.2‑litre naturally aspirated or turbocharged diesel with mechanical or electronic injection, depending on the version. Key points:
MWM 4.12 TCE – 4‑cylinder, 3.2 L, often used with Bosch electronic injection but with different injector part numbers.
Common original injector numbers for this engine include:
Using injector 0445120162 in this engine would be incorrect in most cases, because:
The flow rate, spray pattern, and injector length differ.
The electrical connector and solenoid characteristics may not match the ECU calibration.
