2003–2006 Dodge Sprinter 2.7L CDI Shop Manual (P/N 81-370-06070, 81-370-06075, 81-370-06076)

Built around the 2006 VA factory service information, this five-PDF set covers North American Sprinter repair for the 2.7L five-cylinder CDI platform and NAG1 automatic transmission. The procedure depth and reliance on DRBIII diagnostics, precision measuring equipment, specialty fixtures, and refrigerant and fuel-system service tools make it best suited to professional technicians and experienced owners with a properly equipped workshop.

• Five-volume PDF set: 2,300 pages total - 2006 VA Service Manual, 1,458 pages; Powertrain Diagnostic Manual, 292 pages; Body Diagnostic Manual, 312 pages; Chassis Diagnostic Manual, 94 pages; and Transmission Diagnostic Manual, 144 pages.
• 2.7L diesel engine repair: Covers engine removal and installation, compression and cylinder leak-down testing, cylinder-head inspection, camshaft positioning and tappet-clearance checks, crankshaft and piston work, oil-pump service, and timing-chain removal, installation, and adjustment.
• Common-rail fuel system: Details low-pressure pump testing, air-in-fuel and injector leak-quantity diagnosis, high-pressure pump and rail service, fuel-pressure sensor and solenoid testing, injector removal, cleaning, installation, and DRBIII injector-classification programming.
• NAG1 transmission service: Includes unit removal, internal disassembly and assembly, K1-K3 input and B1-B3 holding clutches, electrohydraulic control unit, oil pump, planetary geartrain, torque converter, fluid/filter service, end-play setup, hydraulic diagnosis, and final installation.
• Driveline, steering, and brake work: Provides two- and three-piece propeller-shaft angle, balance, and runout procedures; SRW/DRW rear-axle and differential repair; suspension and alignment work; power-steering flushing and bleeding; plus base-brake, parking-brake, and Bosch 5.7 ABS/ESP service.
• System-level diagnostics: Four dedicated diagnostic volumes supply DRBIII fault tests, active and stored DTC logic, symptom tests, verification routines, component locations, connector pinouts, schematics, and test charts for powertrain, body, Bosch 5.7 chassis controls, and NAG1 transmission systems.

Coverage and Configuration

The VIN decoder covers Dodge, Freightliner, and Mercedes-Benz identifiers for 2006 VA 4x2 vehicles, including U.S. model code P. For 2500/3500 fitment, match the van to model/cab/weight codes D1-D7, which distinguish Class G and H configurations, 118-, 140-, 158-, and 159-inch wheelbases, and 15- or 16-inch wheel applications. Engine codes 41-44 identify 2.7L Diesel 612 ME9/MF1 and 647 MC0/MF2 builds. Repair sections further separate single- and dual-rear-wheel hardware, and the rear-axle data covers both 3.73 and 4.11 ratios.

Additional Service and Electrical Content

Beyond the core engine and drivetrain chapters, the service manual addresses cooling and accessory drive, turbocharger and charge-air plumbing, front and rear HVAC, the supplemental cabin heater, doors and stationary glass, frame dimensions, body opening measurements, and gap-and-flush specifications. Emissions coverage is specifically centered on the crankcase-ventilation heater and breather plus the EGR valve and cooler, with the catalytic converter handled in the exhaust section.

The wiring material goes well beyond a basic schematic index. Representative drawings include 8W-10 Power Distribution, 8W-30 Fuel/Ignition System, 8W-31 Transmission Control System, 8W-35 Antilock Brakes, 8W-42 Air Conditioning-Heater, and 8W-80 Connector Pin-Outs. Ground, splice, fuse-block, CAN/K-line communication, connector-location, and circuit-repair information supports fault isolation across the vehicle.

Factory Tools, Diagnostics, and Repair Cautions

Special-tool charts cross-reference Mercedes and Miller numbers, including Miller 8929 camshaft locking pins, 8932 crankshaft lock, 9525 timing-chain guide/retainer, C-3339 dial indicator, 8266 end-play set, and 8902A transmission seal installer. Body diagnostics also identify the 8310 and 8443 airbag load tools, while the diagnostic manuals specify DRBIII, electrical meters, an oscilloscope where applicable, and the required test leads.

The fuel chapter warns that high-pressure lines must be replaced after disassembly and routed so they cannot contact each other or nearby parts; contamination can rapidly wear injectors and plug nozzle holes. The NAG1 installation pages protect the pump seal and converter hub during insertion and require full seating in the oil-pump gears; clutch-disc order and matched valve-body components must also be preserved.

The 2006-labeled Powertrain Diagnostic PDF itself states coverage for 2005 Sprinter vehicles with the 2.7L common-rail diesel. Confirm ECM and vehicle applicability before using that volume's DTC tests on a 2006; the main 2006 service manual remains the repair and removal reference.

Follow the manual's pressure-relief, fuel-handling, lifting, airbag-disable, brake, and refrigerant-safety procedures before beginning work.
