About the S-Class

A full-sized luxury sedan, the S-Class was built and sold by the German automaker Mercedes-Benz.

One of the longest-running models, the S-Class made its debut in 1954 and to this day can be purchased as either a 4-door sedan or as a 2-door coupe.

Currently in its sixth generation, buyers can choose between either a 7 or 9-speed transmission and where it is considered a high-class motor, it competes with the likes of the BMW 7-Series, Audi A8, Jaguar XJL, Land Rover’s Range Rover and the Volkswagen Phaeton.

P1453 is a common code that can be associated with the S Class, essentially, it means that the exhaust gas temperature sensor 1 is open. This could be caused by a number of reasons and drivers are advised to check the following; the gas temperature sensor, the gas sensor harness and the exhaust gas temperature sensor circuit. As it can be difficult to find the exact cause, its recommended to consult a mechanic who would typically take one hour to discover the problem and give a diagnosis.

Another code that displays often is P0300, which shows a misfiring inside a cylinder. This typically happens when not enough fuel is burned or when the spark plug is damaged leading to a bigger problem with the catalytic converter. Obviously worn-out spark plugs can be the cause, but so could defective fuel injectors, and EGR valve blockage or a leaking head gasket.

P0305 is also a usual code for the S Class, it means that there is a misfiring in cylinder 5 and people are advised to stop driving immediately and seek out a mechanic. As this can be caused by a faulty spark plug to low engine compression, the variables mean that the vehicle should be taken to a shop for further diagnostic investigation.
