Engine Intelligence
VW / Audi / Seat / Skoda 2.0 TDI PD (BKD era — unit injector) BKD
Common symptoms
- Rough idle with single-cylinder knock
- Hard starting, especially cold
- Loss of power / limp mode
- Misfire entries on individual cylinders
- Increased tappet-style noise from the head
Documented failure modes
- Unit injector (Pumpe-Düse) wear causing calibration drift and rough running
- Injector solenoid faults logging cylinder circuit codes
- Injector loom and connector wear under the rocker cover causing intermittent faults
Diagnostic guidance
- This is a Pumpe-Düse (unit injector) system — there is no common rail; diagnosis differs from CR engines
- Check the injector wiring loom under the rocker cover first — it is a known wear point on this platform
- Unit injectors are cam-actuated: inspect the camshaft lobes when replacing injectors on high-mileage engines
- Torque and alignment of the injector clamps is critical — follow the manufacturer procedure exactly
Fitment note: PD unit injectors differ by output and production year — match the 038130073/03G130073 reference etched on the injector body, not just the engine code.
Why this injector?
- Fits the BKD engine code used in the AUDI A4 and related diesel variants.
- Bosch diesel injector — flow-tested and calibrated on common-rail equipment before despatch.
- Commonly specified when investigating rough idle, injector knock, smoke or poor fuel economy on BKD engines.
- 12-month warranty, free UK delivery and no core exchange required.
