What can we say, the Germans are just ahead in everything they choose to accomplish and Mercedes decided to prove just that with one model. The name, Sonderklasse. Since its first Generation in 1972 it was known to exceed every human expectation of what the automotive industry should be. But it was the W126 Mercedes-Benz 350SD & SDL S-Class that proved Luxury, Technology, and Efficiency can be a wondrous coefficient. With that being said, eManualOnline has an updated Mercedes 350 Repair Manual with exploded diagrams to aid you in any reparation necessary.

The 2nd generation S-Class was released in 1979 bringing a new era of styling. Under Mercedes “Efficient Energy” program the W126 integrated new alloy body panels and aluminum engine components to reduce fuel consumption by 10%. Even the Mercedes classic chrome bumpers were removed for weight reduction and drag in favor of Polyurethane bumpers.

Not only did Mercedes strive for economy but also safety. The S-Class W126 was the first to incorporate Air Bags along with Traction Control as a standard option. Along with the invention of Seat Belt Tensioners activated by sensors that lock the seatbelt when impact or hard braking is felt. Because of these life saving additions the S-Class won the U.S. Highway Loss Data Institute “Safest Passenger Car of the Year” in 1988 and 1989.

Luxury and comfort is what set the Mercedes 350SD & SDL apart from its successor. The W126 was the first to offer 8-way adjustable seating with a heater option for those cold winter days. The car could also be ordered with automatic climate control that would self regulate airflow upon the sunroof or window being open.

However, the Mercedes 350SD & SDL did have one major flaw. The new 3.5 liter Inline 6 diesel engine. With common symptoms as excessive oil consumption, mechanical noise, smoke, and a throbbing idle. Before the 50,000 mile mark. Proving overboring the previous hefty 3.0 diesel was a mistake. Enthusiast blame the overboring of the cylinders causing oil to sip pass the pistons rings. Others have torn down these engines to find bent connecting rods. Although Mercedes did at the time offer warranties on the engines that gave out prematurely.
