0432133795 — Frequently Asked Questions
Verified answers about the Bosch 0432133795 2.5 TDI V6 Nozzle-Holder Injector (Audi A4/A6/A8, VW Passat, Skoda Superb).
What is injector 0432133795?
0432133795 is a Bosch pump-line-nozzle holder (with needle-lift sensor) diesel injector for the Audi / VW / Skoda 2.5 TDI V6. It is supplied remanufactured, bench-tested and calibrated to OEM specification.
Which vehicles use 0432133795?
It is fitted to the Audi / VW / Skoda 2.5 TDI V6 — including Audi A4 (B6) 2.5 TDI V6 (AKE/BCZ/BDG/BFC); Audi A6 (C5) 2.5 TDI V6 (AKE/BAU/BDH/BCZ/BDG/BFC); Audi A8 (D2) 2.5 TDI V6 (AKE/BCZ); Volkswagen Passat (B5) 2.5 TDI V6 (AYM/AKE). Confirm fitment by OE number and engine code.
What type of injector is 0432133795?
It is a Bosch Pump-Line-Nozzle Holder (with needle-lift sensor). Always confirm the OEM markings on the injector body before fitting.
Does 0432133795 need coding when fitted?
No — it is a mechanical nozzle-holder fed by the VP44 distributor pump, so no electronic injector coding is needed. Ensure the needle-lift-sensor unit goes back on cylinder 1.
What are the symptoms of a failing 0432133795?
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 0432133795 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 0432133795 a common-rail injector?
No. The 2.5 TDI V6 (AKE etc.) uses a Bosch VP44 distributor pump feeding mechanical nozzle-holders. 0432133795 is the nozzle-holder assembly, with a needle-lift sensor on the cylinder-1 unit for timing.
Why does my 2.5 V6 TDI run rough or lack power?
Worn nozzle-holders raise opening pressures and skew the spray, unbalancing the V6. Have each holder bench-tested; the cylinder-1 needle-lift sensor unit must be functional for correct injection timing.
