BOSCH 0445110685 VW Audi 2.0/3.0 TDI Injector - 03L130855C
03L130855C 03L130855CX 03L130277J 03L130277Q F00VC01503 DLLA160P2176 1800 bar peak Product Overview
The BOSCH 0445110685 is a 110-series solenoid common rail injector from the CRI 2-16 family, engineered for VW / Audi 2.0L TDI (EA189) passenger-car applications. It does NOT fit the 2.7L EA270 or 3.0L EA897 V6 TDI engines - those take a different injector family (Audi OE 059130277xx, Bosch 0445116015 / 0445116023 / 0445117022). The 1800 bar peak rail pressure and 7-hole DLLA160P2176 nozzle (internal Bosch code 0433172026) enable stable pilot + main injection sequences. The F00VC01503 control valve meters fuel via electromagnetic solenoid actuation. OEM codes 03L130855C / 03L130855CX / 03L130277J / 03L130277Q map to this Bosch code 0 445 110 685. Aftermarket replacements require IMA coding via VCDS / ODIS - skip the coding and you will get P2146 / P2149 fault codes and rough idle.
Always verify the OE reference (03L130855C / 03L130277J etc.) on your existing injector body before ordering. 0445110685 shares the F00VC01503 control-valve group with sister SKUs 0445110611, 0445110646, 0445110659, 0445110673 but each carries a unique IMA calibration - NOT interchangeable without ECU re-coding.

Frequently Asked Questions
Will 0445110685 fit a 2009 Audi A4 2.0 TDI (EA189)?
Yes - the 0445110685 is a confirmed fitment on the Audi A4 2.0 TDI from 2009 through 2015 (EA189 platform, engine codes CBDB / CFFA / CFHD). Verify the OEM code stamped on your failed injector - if it reads 03L130855C, 03L130855CX, 03L130277J, or 03L130277Q, you have the right injector. VW / Audi part numbers from V03L130855CX are also equivalent.
What is the difference between 0445110685 and 0445110646?
Same body and same CRI 2-16 system, different IMA calibration code stamped on the label. 0445110646 is the lower-flow / earlier variant typically used on the 88-105 kW (120-143 HP) A3 / A4 2.0 TDI. 0445110685 is the higher-flow variant for the 125-130 kW (170-177 HP) 2.0 TDI applications (A4 / A5 / Q5 with CAHA, Golf / Passat with CBBB / CFGB). The four sister codes 0445110611 / 0646 / 0659 / 0673 / 0685 are all in the same body family - verify the stamped Bosch code and use the exact match.
What control valve is on 0445110685 and how do I verify it?
Control valve: F00VC01503 (part of the F00VC015xx series shared by the EA189 CRI 2-16 family). Internal nozzle: DLLA160P2176 (Bosch code 0433172026), a 7-hole design with 160° spray angle. To verify: remove the injector and check the white sticker label on the solenoid body - the F00VC01503 valve is a solenoid type (not piezo). If you see a different control valve code, the injector has been previously replaced with the wrong variant.
Can I use 0445110685 on a 1.6L TDI (EA111) or a 1.4L TDI?
No - the 1.6L TDI EA111 (engine code CAYC) and the 1.4L TDI use a different Bosch 110-series injector (typically 0445110xxx in the 750-790 range) with a smaller nozzle body and a different control valve shim. The 0445110685 is sized for the 2.0L EA189 platform only. Do not be misled by sellers who claim cross-fitment - the IMA calibration block is engine-platform specific.
What are the symptoms of a failing 0445110685 injector on a VW / Audi 2.0 TDI?
Common symptoms: fault code P2146 (injector Group A circuit/open), P2149 (cylinder 4 open circuit), rough idle, misfire on cold start, white or black smoke, loss of power, and reduced DPF regeneration efficiency. An AudiWorld forum case documented a 2008 A4 with P2146 - resistance testing showed cylinder 4 injector at 99 ohms (should be ~2.4 ohms), confirming a failed coil requiring replacement. After coil + wiring harness replacement and VCDS recoding, the vehicle ran normally.
What is the correct installation torque and procedure for 0445110685?
The OE-specified procedure for EA189 (2.0 TDI) injector hold-down bolts: (1) Clean the injector bore and M8 thread with a wire brush and compressed air. (2) Fit new copper washers on both the high-pressure and leak-off connections. (3) Install the injector and hand-tighten the two hold-down bolts. (4) Torque each bolt to 8 N·m. (5) Rotate each bolt a further 180°(torque-to-yield - these are stretch bolts and must be replaced every removal). (6) Connect the 16-pin electrical connector and run the lift pump to prime. (7) Code via VCDS or ODIS. The 8 N·m + 180° procedure is confirmed by OE supplier Darkside Developments (WHT004739 bolts) and is the standard for all 2.0 TDI CR engines in the EA189 family.
Do I need to code the ECU after installing 0445110685 on a VW / Audi?
Yes - VW / Audi EA189 ECUs require cylinder-specific IMA coding via VCDS (Ross-Tech), ODIS (dealer tool), or a compatible aftermarket tool such as Autel MaxiSys. Skip the coding and you will get fault codes P2146 (cylinder 1 injector short to ground), P2149 (cylinder 4 injector open circuit), rough idle, and a drop in DPF regeneration efficiency. Replace all 4 injectors as a set and code the IMA block once.
What is the warranty on 0445110685?
Standard 12-month warranty from FuelPartsDB. The warranty covers manufacturing defects and premature coil failure. It does NOT cover damage caused by incorrect installation (over-torqued bolts, cross-threaded connections), improper coding (unmatched IMA values causing coil overheating), or use on incompatible engine platforms (EA111 / EA189 mismatch). Always verify the engine code and OE part number before ordering.
What is the most common ordering mistake for 0445110685?
The most common mistake is ordering 0445110685 for a 1.6L TDI (EA111 / CAYC engine) or confusing it with a 0445110xxx 750-range injector that IS correct for the 1.6L. Another frequent error is substituting 0445110646 (lower-flow, for 88-105 kW) when the vehicle actually requires 0445110685 (higher-flow, for 110-130 kW). Always verify by checking the failed injector's stamped OE code (03L130855C / 03L130277J / 03L130277Q) - not just the engine model. The 0445110685 is also sometimes confused with the CRI1 0445110xxx 9xx-series used on pre-2008 PD engines - those have a different connector pin-out and are NOT interchangeable.
