In actual fact, modern cars are full of it and it could be the sign of a critical malfunction. Down below we will talk about the different possible origins of burnt plastic smell:
- Transmission oil: This is the most important possible origin of such an odor. In actual fact, the function of gear or transmission oil is to lubricate the different components of your gearbox so that all the gears and pinions are not broken, it as well has a second function as a temperature regulator. However, as time passes, the oil will lose its efficiency and will not lubricate the parts and control the temperature as well, which will trigger the oil to overheat and thus give off that burnt plastic smell on your Mercedes Classe S. You risk pre-wearing your gearbox if you don’t take care of it.
- The accessory belt: Nevertheless rarer, it is possible with wear and tear that your belt, which is principally done of rubber, will decline and no longer rotate entirely on its axis. With the friction that this will trigger the plastic will heat up and burn out, this reaction will generate a strong smell of burnt plastic or rubber in the engine block of your Mercedes Classe S.
- Defective hose wear: This case happens specifically on Mercedes Classe S that are starting to get a few years old or that have stayed a long time without rolling. In fact, storing your vehicle contrary to what you might presume will trigger the plastic parts to wear out more quickly. Hoses are the first to be suffering from this phenomenon. The rubber will disintegrate little by little and with the rise in heat of the fluid that circulates in it, it may melt. The risk of this issue is the breakage of the accessory belt.
- A body component: Less general, specifically present on Mercedes Classe S’s that have suffered a small shock. Following a front or rear impact, wheel arches, bumpers or other plastic body parts that may have been bent may rub against one of your wheels and give off that burnt plastic smell.
