Delphi 7135‑617 Repair Kit

Please check the part number against your part number if you are not sure it is the right item contact us.

What it is

• It’s a repair kit for an injection nozzle (also sometimes described as a “nozzle + valve” set) for a common-rail diesel injector system made by Delphi. 

• The manufacturer part number is 7135-617.

• It replaces or repairs the internal components of an injector: typically the nozzle (spray tip) and a valve/control component for the injector. For example one source lists: “7135-617 … [valve + nozzle]” in the description. 

Key Features & Specifications

• Brand: Delphi.

• OE / Cross-Reference Numbers:

  • Alternative numbers include: 28239295, L197PBD, L197PRD, L349PRD, R06001D.

  • It is sometimes listed alongside injector part numbers such as R06001D, R03801D.

• Applications / Fitment:

  • Commonly used in certain vehicles of the groups Peugeot and Citroën with 2.0 HDi engines (engine code DW10BTED4) from approx 2004 onward.

  • Specific models listed: PEUGEOT 307, 308, 407, 508, CITROËN C4, C5, etc.

• Weight / Origin:

  • One listing shows weight: 0.059 kg and country of origin: Italy. 

• Part of the kit: Though the exact contents may vary by supplier, the “kit” typically contains the nozzle seat/spray tip and the valve/control component necessary for the injector internals.

What it does

• In a common-rail diesel system, injectors have very high pressures and precision components. Over time the nozzle spray pattern, the needle seating, or the control valve inside the injector may wear or be contaminated.

• This kit allows for renewal of those critical internal parts rather than replacing the entire injector, thereby restoring proper spray, sealing, and fuel metering.

• By replacing the nozzle and valve, it helps ensure the injector can deliver the correct fuel quantity and maintain correct combustion, reducing misfire, smoke, rough running or fault codes.

Why it matters / Benefits

• Cost-effective: Rather than replacing the full injector unit (which can be expensive), this kit offers a more economical repair route.

• Restores performance: Wear inside an injector can degrade engine performance, increase emissions, cause rough idle or poor fuel economy. A proper kit can restore close to original performance.

• Quality brand: Delphi is a well-known supplier in diesel injection systems, so using a genuine or good quality replacement kit is important for reliability.

• Correct fitment: Because it’s designed for specific nozzle/valve combinations (e.g., R06001D injectors, etc), fitting the correct kit helps avoid incompatibility issues.

Things to check / Tips

• Ensure compatibility: Verify your vehicle’s engine code, injector type (for example R06001D / R03801D), production year and fitment list before purchasing. The wrong kit may not fit or function properly. 

• Quality and sourcing: Make sure you’re buying from a reputable supplier. Some parts may be aftermarket or replicas.

• Cleanliness: When performing the repair, cleanliness is critical. These injector internals operate under extremely high pressure; any contamination can lead to failure.

• Replacement procedure: The repair may require special tools (for example for removing the old nozzle seat/valve) and calibration/bleed of the fuel system after installation.

• Associated damage: If the injector showed signs of major wear or damage (eg burnt tip, broken needle, etc) simply replacing the nozzle/valve may not fully restore the injector; full injector replacement might be necessary in those cases.

 Please be aware you may be charged import duties in your country! Pumps and Injectors carry a 12 month warranty against manufacturing or remanufacturing defects, limited to the cost of the replacement part only.
