Siemens VDO / Continental H8201100113 Diesel Injector

On the 1.5L dCi/CDI platform, a failing Siemens VDO / Continental H8201100113 injector typically presents as: hard starting or extended cranking; rough or uneven idle; loss of power under load; excess smoke from the exhaust; cylinder misfire or contribution fault codes.

When two or more of these appear together, suspect the injector before peripheral systems — a comparative leak-off test and live-data cylinder-balance review will isolate the failed unit without tear-down.

The documented failure modes on this platform are: injector back-leak beyond specification; nozzle wear degrading the spray pattern; combustion gas leaks past the injector seat washer.

Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.

Run a comparative leak-off (back-leak) test across all injectors before condemning a single unit. Compare requested vs actual rail pressure in live data at idle and under load. Inspect injector connectors and wiring before replacing hardware.

Never condemn a common-rail injector on a fault code alone — codes identify the circuit or cylinder, while leak-off volumes and correction values identify the component.

Each remanufactured H8201100113 is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is then calibrated on a common-rail test bench against the manufacturer's specification sheet — delivery, back-leak and response are all verified before the injector is sealed and despatched with its calibration data on file.

Every unit carries a 12-month parts warranty and free UK delivery.

The H8201100113 trusted family covers 22 verified vehicle fitments across 4 makes: Renault, Dacia, Nissan and Mercedes-Benz. Every fitment listed on this page is registry-verified — no scraped or assumed applications.

H8201100113 supersedes or cross-references 12 further OE numbers, including 8201100113, A2C59507596, A2C53381618, 8201041272, 1660000Q1W, 16600-00Q1W, 6070700087 and A6070700087. Always match the reference etched on your failed unit's body — cross-references within a family are verified equivalents, but etched numbers remain the source of truth.
