About the C-Class
Referred to as a compact executive car, the C-Class was designed and manufactured by the German automaker Mercedes-Benz, specifically Mercedes-Benz Group AG.
Its first model sold in 1994, the C-Class was the smallest model at the time for the company and was originally available with a ‘4MATIC’ four-wheel drive option.
The C Class has been manufactured in a number of styles and can currently be purchased as either a station wagon or a fastback coupe.
Designed by Murat Gunak, the C-Class spent 8 years in development and shortly after its release, became the safety car for Formula one.
Second generations were sold from 2000 onward after patents were filed for the car’s design.
There was a range of engines for these newer models, a range of inline-four and V6 petrol engines and five diesel options.
The C-Class is currently in its fifth generation, it predictably looks significantly removed from its original model and had a lengthened wheelbase specifically for the Chinese market.
To add to this lineup, Mercedes-Benz released the C-Class All-Terran, a car intended for off-road use and styled in a crossover estate manor.
For customers looking for a C-Class alternative, options could be found in the BMW 3 Series, Audi A4, Vauxhall Insignia, Jaguar XE or the Skoda Superb.
Some usual fault codes that can come from this vehicle are:
- P0410 – Detection of the engine O2 sensor, in that it does not detect an increase in the oxygen levels.
- P0303 – a misfiring in cylinder 3 that is detected by the ECU.
- P0113 – This code points to an issue with the vehicle’s intake air temperature sensor.
- P0017 – A code that covers any surrounding problems with the car’s camshaft/crankshaft. In order to perform properly, the car’s engine should be perfectly synchronized with the aforementioned crank and camshaft.
- P0340 – This could mean that there are faulty wires or a sensor failure creating an issue with the camshaft position.
