This comprehensive Mercedes-Benz maintenance manual covers model series 201, 107, 123, 124, 126, 129, and 140 from 1981 to 1993, providing official factory maintenance schedules, service procedures, inspection criteria, torque data, wiring diagrams, fluid specifications, and job-number cross-reference tables for owners and technicians who value the legendary longevity and precision engineering of classic Mercedes-Benz vehicles.
1981-1993 Mercedes-Benz Model 201 107 123 124 126 129 140 Series Maintenance Manual PDF
VEHICLE/EQUIPMENT INTRODUCTION:
The Mercedes-Benz lineup spanning model series 201, 107, 123, 124, 126, 129, and 140 represents perhaps the most respected era of German automotive engineering, from the early 1980s into the mid-1990s. These vehicles earned legendary status among enthusiasts and professional mechanics for their build quality, over-engineered components, and longevity well beyond 200,000 and even 300,000 miles. The 201 series introduced the compact 190, the 107 series encompassed the iconic SL roadster, the 123 and 124 were mid-size sedans and wagons celebrated for their diesel engines, the 126 was the flagship S-Class sedan, the 129 introduced the SL with retractable hardtop, and the 140 established the modern S-Class. Every series shared Mercedess commitment to precision engineering, and this maintenance manual provides the official service procedures, torque data, and inspection criteria needed to preserve these classic Mercedes-Benz vehicles. Maintained correctly, these automobiles can provide decades of refined driving experiences.
SERVICE & REPAIR SCOPE:

- Cooling system coolant replacement specifications and bleed procedures
- Drive belt inspection and replacement tension setting
- Brake system fluid replacement bleeding procedure with ABS considerations
- Transmission fluid change automatic and manual variant specifications
- Differential oil specification fill volume and drain procedure
- Steering system power steering fluid specification and bleed routine
- Suspension strut and shock absorber inspection mounting point evaluation
- Electrical system battery testing alternator output verification
- Spark plug replacement gap specification and ignition timing check
- Air filter replacement fuel filter service intervals
- Emission system component inspection and function test
- Climate control refrigerant service A/C system maintenance
- Door hinge adjustment window regulator service seat mechanism repair
- Body panel alignment measurement and specification
TECHNICAL SPECIFICATIONS:
- Manufacturer: Mercedes-Benz AG
- Model series: 201, 107, 123, 124, 126, 129, 140
- Years covered: 1981-1993

- Total pages: 330+ pages of technical content
- Format: Digital PDF, searchable, indexed, iPad-ready
DIAGNOSTIC INFORMATION:
- Hard starting in diesel engine variants: Verify glow plug relay function, test each glow plug for continuity, bleed fuel system at filter and injector connections, check injection pump timing, confirm fuel filter is not restricting flow
- Automatic transmission harsh shifts or delayed engagement: Check transmission fluid level and condition, burnt fluid indicates internal wear, verify throttle cable or vacuum modulator adjustment, inspect shift solenoid wiring connectors
- Power steering moaning noise when turning: Check fluid level and top up to specification with approved Mercedes power steering fluid, inspect fluid lines for pinched hoses or restrictions, bleed air from system by turning lock-to-lock several times
- Air conditioning insufficient cooling: Verify refrigerant charge with manifold gauge set, check compressor clutch engagement, inspect condenser for debris blockage, test blower motor resistor block
- Oil leak at valve cover gasket: Clean area thoroughly to confirm leak source, remove old silicone or gasket material from sealing surfaces, install new O-ring gasket per Mercedes specification, torque cover bolts evenly in sequence
- Window operation slow or inoperative: Test window motor current draw, clean window runner channels and apply silicone spray, inspect regulator cable for fraying, verify door control switch contacts are clean and free of oxidation
