Hard starting when warm; uneven idle with single-cylinder knock; loss of power / limp mode with rail-pressure faults; injector group supply-voltage faults; excess smoke on hard acceleration. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Piezo injector electrical failure logging group voltage codes; injector back-leak rising with temperature on high-mileage units; fuel contamination damage following hp pump wear. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
Six-cylinder V layout — compare leak-off volumes across both banks before condemning an injector. Group voltage codes usually mean one shorted piezo injector pulling down the shared supply — test each in the group. Injector coding via ODIS/VCDS is required after replacement. Never condemn a common-rail injector on a fault code alone.
Each remanufactured 0445116022 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 0445116022 trusted family covers 9 verified vehicle fitments across 3 makes: Audi, Porsche and Volkswagen. Every fitment listed is registry-verified.
0445116022 cross-references 16 further OE numbers, including 0445116023, 0986435357, 0986435379, 0445116007, 0445116008, 0445116014, 0445116015 and 0445116047. Always match the reference etched on your failed unit's body.
