Depth Of Information:
Comprehensive; covers everything from basic maintenance to complex component overhaul and system diagnostics. Likely includes detailed step-by-step instructions with diagrams and illustrations.
Gasoline Engines:
M111 (2.0L, 2.3L I4), M112 (2.4L, 2.6L, 2.8L, 3.2L V6), M113 (4.3L, 5.0L V8, including AMG variants like M113 E55).

OM601 (2.0L I4 Diesel), OM604 (2.2L I4 Diesel), OM605 (2.5L I5 Diesel), OM606 (3.0L I6 Diesel), OM611 (2.1L I4 CDI - Common Rail Direct Injection), OM612 (2.7L I5 CDI), OM613 (3.2L I6 CDI).
Horsepower Torque Range:
Varies significantly by engine. Typically ranges from ~130 hp for base diesel models to over 340 hp for V8 and AMG variants. Torque figures also vary widely. Specific data would be detailed within the manual.
Injection Type:
Multi-point fuel injection (MPI) for gasoline engines, common rail direct injection (CDI) for later diesel engines. Early diesels may use mechanical injection pumps.
ECU Type:
Bosch Motronic or Siemens engine control units (ECUs) depending on engine and model year. Specific diagnostics and programming would be covered.
Oil Change Interval:
Typically every 10,000-15,000 miles (16,000-24,000 km) or 12 months, depending on driving conditions and oil specification used. Service indicator system (Assyst) would guide actual intervals.
Major Service Intervals:
Spark plugs, transmission fluid, differential fluid, coolant, and brake fluid would have scheduled replacement intervals, often around 30,000-60,000 miles (50,000-100,000 km) for various items. The manual would detail these precisely.
Engine Oil:
Varies by engine, but typically API SL/SM or ACEA A3/B4, viscosity grades like 0W-40, 5W-40, or 5W-30. MB 229.5 or 229.3 specifications are common for gasoline engines.
Coolant:
MB 325.0 or MB 325.5 (ethylene glycol based) antifreeze/coolant, typically a 50/50 mix with distilled water.
Brake Fluid:
DOT 4 or DOT 4 Plus brake fluid.
Common W210 Issues:
Rust/corrosion (especially on fenders, rocker panels, and around windows), MAF sensor failure (diesel models), biodegradable wiring insulation degradation (early models), fuel pump failure, window regulator failures, vacuum leak issues, electronic climate control module (ECC) faults, transmission conductor plate issues (5G-Tronic).
