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. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
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. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
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. Never condemn a common-rail injector on a fault code alone.
Each remanufactured 03G130073G is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is calibrated on a common-rail test bench against the manufacturer's specification — delivery, back-leak and response verified — and despatched with a 12-month parts warranty and its calibration data on file.
The 03G130073G trusted family covers 8 verified vehicle fitments across 4 makes: Audi, Seat, Skoda and VW. Every fitment listed is registry-verified.
03G130073G cross-references 11 further OE numbers, including 03G130073GX, 0414720454, 0414720404, 0986441516, 0986441566, MN980235, DI427 and 87119. Always match the reference etched on your failed unit's body.
