0445110156

The 0445110156 carries Mercedes-Benz OE reference A6480700187 (also listed as 6480700187 or 64807001870080). To verify, locate the build plate on the engine block (typically on the top of the OM646/OM647/OM648 cylinder block, near the injectors). The OE number printed on the original injector label must match A6480700187 for any of the W211 E-Class CDI variants (2002-2006, W220 S-Class CDI 2002-2004, S211 T-Model 2003-2006). If the OE number printed on the build plate is 6480700087 (note: 0087, not 0187), the correct injector is 0445110128 - not the 0445110156. The two are mechanically similar but carry different IMA calibration codes and are NOT interchangeable.

The 0445110156 is fitted with the Bosch F00VC01328 solenoid control valve (F00VC01xxx series, CRI/IPS19/ZEREAK20S generation). This valve is the same control valve group used on the sister SKUs 0445110155 and 0986435135. The valve stamping is found on the solenoid connector cap (the top of the injector body, just below the electrical pins). DO NOT confuse F00VC01328 with the wiring harness connector code - these are different. The F00VC01328 calibrates the HP rail pressure at 1600 bar peak for the OM646/OM647/OM648 CDI platform.

0445110156 and 0445110155 share the same F00VC01328 control valve group and are mechanically interchangeable on Mercedes E/S-Class CDI platforms, BUT they carry different OE references (A6480700187 vs 0986435135 exchange number). In practice, the 0445110155 is the exchange number that distributors substitute for the 0445110156 (and vice versa) - both fit all OM646/OM647/OM648 platforms. Each has a unique IMA calibration code stamped on the solenoid body, so when ordering the replacement, you may receive either SKU depending on stock. The 0986435135 is the Bosch aftermarket exchange number for either of these. For vehicles outside the W211/W220/S211 family (e.g. W203 C-Class), check the build plate OE.

The 0445110156 fits Mercedes-Benz W211 E-Class CDI variants (E 200 CDI / E 220 CDI / E 270 CDI / E 280 CDI / E 320 CDI, 2002-2006) with the OM646 (2.2L) / OM647 (2.7L) / OM648 (3.2L) CDI engines. For W203 C-Class C 220 CDI with the OM646 engine (2004-2007), the 0445110156 is the correct fitment (Mercedes OE A6480700187). It also fits the Sprinter II (NCV3, 4-/5-cyl variants, OM646, 2006-2009) and the CLK (C209, OM646/OM647, 2002-2005). Verify the OE stamping on the engine build plate before ordering.

Common failure symptoms on OM646/OM647/OM648 CDI engines: (1) OBD fault codes P0201-P0206 - injector circuit malfunction on cylinders 1-5, with P201C / P201D / P201E for IMV/IMA calibration errors; (2) rough idle and misfires on a single cylinder after cold start, frequently misattributed to glow plugs; (3) black smoke on acceleration combined with > 8% fuel consumption increase; (4) hard cold start with delayed exhaust smoke (rail pressure build slowly because F00VC01328 valve is degraded); (5) excessive return flow at idle > 100 mL/min confirms internal valve or nozzle leakage. Diagnose with a DCI 200 or EPS200A test bench, then a STAR Diagnose cut-out test before condemning the injector.

Three torque locations on the OM646/OM647/OM648 platform - each with different values: (1) High-pressure fuel line banjo nut (rail side): 25-30 N·m with a dedicated 17 mm flare nut wrench; NEVER use an impact wrench - shock loading can deform the F00VC01328 valve assembly and cause a no-start condition; (2) Injector hold-down clamp bolt: M6 stud at 20 N·m + 90° angle (Bosch CRIN2 standard; verify against the Mercedes WIS workshop manual for the specific variant); (3) Fuel feed tube connector nut: 1.25 N·m (11 in·lb) - very light torque, overtightening causes injector body cracking. Tools: 17 mm flare nut wrench, 10/12 mm sockets, calibrated 3-30 N·m torque wrench. Always fit new copper sealing washers; reused seals are the #1 cause of combustion gas leakage post-install.

Yes. The 0445110156 is a complete solenoid common rail injector assembly with cylinder-specific IMA calibration values stored in the engine ECU. After installation, use Mercedes STAR Diagnose (or aftermarket scanner with Mercedes CDI coverage, e.g. iCarsoft i980 or Autel MaxiDAS) to code the injector's IMA values to the ECU. Common installation mistakes: (a) installing the injector without coding, resulting in cylinder imbalance, rough running, and persistent P201C / P201D codes even with a new injector; (b) entering the wrong cylinder number - double-check which cylinder the failed injector was in before coding (the OM646 is an inline-4 or -5, cylinder numbering starts at the front of the engine); (c) using the wrong IMA value - the IMA code for 0445110156 is on the injector label and must be entered to 0.01 mg/stroke precision. Coding clears P020x fault codes that were triggered by the previous failing injector.

Standard aftermarket warranty is 24 months from date of purchase, covering manufacturing defects only (no atomisation, no electrical continuity, or > 100 mL/min return flow at 200 bar bench test). Return conditions: (1) manufacturing defect confirmed by bench test; (2) incorrect fitment confirmed before installation - if the injector does not match the build plate OE (A6480700187) or the engine platform (OM646/OM647/OM648); (3) physical damage in shipping - photograph before installation. Non-returnable conditions: (1) installed and coded to ECU - once the IMA code is written to the ECU, the injector is tied to that specific vehicle; (2) damage from fuel contamination (water, debris, algae) - replace fuel filters and flush HP circuit before installing; (3) over-torqued HP banjo fitting cracking the injector body; (4) cross-installed on non-OM646/OM647/OM648 engines (e.g. OM612, OM651). Keep the laser-etched batch number on the injector body for warranty claims.

Three frequent mistakes: (1) Confusion with 0445110128 (Mercedes OE 6480700087) - these are for different E-Class CDI variants (W211 E220 early production vs late production). Verify the OE stamping on the build plate is exactly A6480700187 (or 6480700187) BEFORE ordering - a 0 → 0 vs 0 → 8 mismatch is the most common return reason. (2) Confusing with 0445110157 / 0445110158 - these are 4-cylinder-only OM646 variants for the W203 C-Class and CLK; while often cross-listed as compatible, the IMA calibration is for the smaller cylinder count engine and may cause rough idle on W211 inline-5 platforms. (3) Buying 0986435135 (aftermarket exchange number) when the engine ECU expects 0445110156 - although mechanically interchangeable, the IMA code stamped on the solenoid body differs, and the ECU may throw a P201C IMA mismatch code. Always verify the OE build plate number first.
