Mercedes W109 Service Repair Manuals

The Mercedes-Benz W108 and W109 are luxury cars that were produced by Mercedes-Benz from 1965 through to 1972 - and 1973 in North America only. The line was an update of the predecessors W111 and W112 fintail sedans.

These cars were a successful venture for Mercedes with good sales in West Germany, and in export markets including North America and Southeast Asia. During the seven-year run, a total of 383,361 units were manufactured. Jump to Manuals

The first W109, the 300SEL was premièred at the Frankfurt Auto Show in 1965.  Its suspension system featured a reinforced rear axle with hydropneumatic compensating spring. The car sat on larger wheels (14”) and had disc brakes on front and rear. The W109 was identical to the W108, but featured an extended wheelbase of 115 mm (4.5 in) and self-levelling air suspension.  By 1967 the fuel consumption of the 3 litre unit in this application was becoming increasingly uncompetitive. For the W109, the 300SEL finally retired the M189 engine, and received the 280Se's 2.8 M130.

In 1966 company engineer Erich Waxenberger transplanted a massive 6.3 L Mercends-Benz M100 V8 from the company's flagship 600 (W100) into a standard W109, creating the first Mercedes-Benz Q-car. Full-scale production of what evolved into the high-end Mercedes-Benz 300SEL 6.3 began in December 1967. Despite its large size, the automaker claimed a 6.3 0-62 mph (0–100 km/h) acceleration time of 6.6 seconds, and top speed of 220 km/h, making it the fastest production sedan, a title it held for many years.

New engines arrived again in late 1969. The first was the 200 hp (149 kW) M116 3499 cc V8 with Bosch D-Jetronic electronic fuel injection. It was shown fitted to the W109 in the Frankfurt Auto Show where the car was christened the 300SEL 3.5. Its performance included a top speed of 200 km/h (124 mph) and 0–100 km/h in 10 seconds.

Within the next few years, the W111 and W113 were phased out and the W108 and W109 were left as the sole survivors of the ageing 1960's family. However, the arrival of the big-block 4520 cc 225 hp (168 kW) M117 engine allowed for a final set of vehicles to be launched in the spring of 1971, and at this time the W109 300SEL 4.5 was destined solely for the US market.

By now the mainstream V8 models were being introduced, and for the W108 and W109, production was already drawing to a close. In September 1972 the last 300SEL 3.5 and 6.3 models rolled off the conveyors. A month later, the final 300SEL 4.5 ended the W109's production.
