What is injector 074130202B?
074130202B is a Bosch nozzle holder (with needle-lift sensor) diesel injector for the VW Transporter T4 2.5 TDI. It is supplied remanufactured, bench-tested and calibrated to OEM specification.
Which vehicles use 074130202B?
It is fitted to the VW Transporter T4 2.5 TDI — including Volkswagen Transporter (T4) 2.5 TDI (ACV/AXG/AYC); Volkswagen Caravelle (T4) 2.5 TDI (ACV/AXG); Volkswagen Multivan (T4) 2.5 TDI (ACV/AXG); Volkswagen Transporter T4 Van 2.5 TDI 88/102/151 PS. Confirm fitment by OE number and engine code.
What type of injector is 074130202B?
It is a Bosch Nozzle Holder (with needle-lift sensor). Always confirm the OEM markings on the injector body before fitting.
Does 074130202B need coding when fitted?
No — the T4 2.5 TDI uses a VP37 distributor pump with mechanical nozzle-holders, so no electronic coding is required. The needle-lift-sensor unit must go back on cylinder 1.
What are the symptoms of a failing 074130202B?
Common signs are rough idle and vibration, hard starting, power loss or limp mode, black smoke and an engine-management light.
What causes these injectors to fail?
Most failures come from poor fuel filtration, contamination and water in the fuel leading to wear, high back-leakage and nozzle coking. Fix the cause before fitting replacements.
Is a remanufactured 074130202B as good as new?
A properly remanufactured injector is stripped, fitted with new wear parts, reassembled and recalibrated on a common-rail test bench to OEM tolerances, then supplied with a warranty.
Should I replace one injector or the full set?
Replace the confirmed faulty injector first. On high-mileage engines fitting a matched set reduces the chance of a repeat fault, but it is not mandatory if the others test within spec.
Do you bench-test the injector before dispatch?
Yes. Every unit is tested for delivery, back-leakage and spray pattern on a calibrated common-rail tester before it leaves us.
Is delivery and warranty included?
Yes — the price includes free UK delivery and a 12-month warranty.
Is 074130202B a common-rail injector?
No. The T4 2.5 TDI uses a Bosch VP37 distributor pump feeding mechanical nozzle-holders. 074130202B is the nozzle-holder assembly; the cylinder-1 unit carries a needle-lift sensor used for injection timing.
Which T4 engines does 074130202B fit?
It fits the 2.5 TDI T4 engines ACV/AUF/AJT/AYC/AYY/AXL/AXG (65/75/111 kW), 1995–2003. Confirm the engine code stamped on your unit before ordering.
