Mercedes Benz CL-Class Fault Codes

About the CL-Class

Referred to as a grand tourer, the CL-Class was a car created by the German automaker Mercedes-Benz.

The first models rolled off the production line in 1992, and these vehicles lasted right up until 2014.

Mercedes Benz says that the CL moniker Is actually an initialism for ‘Coupe Leicht’ (coupe light) and throughout its lifetime it was referred to as the company’s flagship, premium model.

First generations kept the design language of the other Mercedes of the time, sleek but angular lines with a squared-off front grille and transmissions were available as either a 4-speed automatic, or a 5-speed automatic.

There were rivals to the CL-Class with other premium car manufacturers bringing out their own luxury models such as the Infiniti G35 or the BMW M3.

Later models looked extremely different, the latest and third generations had taken 6 years of development to produce a sloping backed version with a number of engine variants ranging from a 4.7-liter V8 twin-turbo up to a 6-liter V12 twin-turbocharged.
