The different possible origins and risks of smell of burnt plastic on a Mercedes Benz CLS Class
So we commence our content with the different possible origins of burnt plastic smell on a Mercedes Benz CLS Class . In general, noticing a plastic or rubber smell is never a good sign. Indeed, modern cars are full of it and it could be the sign of a critical breakdown. Down below we will talk about the different possible origins of burnt plastic smell:
- Transmission oil: This is the most important possible source of such an odor. Indeed, the action of gear or transmission oil is to lubricate the different elements of your gearbox so that all the gears and pinions are not damaged, it as well has a second action as a temperature regulator. Nevertheless, with time, the oil will lose its performance and will not lubricate the auto parts and regulate the temperature as well, which will cause the oil to overheat and thus give off that burnt plastic smell on your Mercedes Benz CLS Class. You risk pre-wearing your gearbox if you don’t take care of it.
- The accessory belt: Although rarer, it is possible with wear and tear that your belt, which is specifically done of rubber, will decline and no longer rotate completely on its axis. With the friction that this will cause the plastic will heat up and burn out, this reaction will create a strong smell of burnt plastic or rubber in the engine block of your Mercedes Benz CLS Class.
- Defective hose wear: This circumstance happens specifically on Mercedes Benz CLS Class that are starting to get a few years old or that have stayed a long time without rolling. In reality, storing your vehicle contrary to what you might think will cause the plastic auto 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 common, specifically present on Mercedes Benz CLS Class’s that have suffered a small shock. Following a front or rear impact, wheel arches, bumpers or other plastic body auto parts that may have been bent may rub against one of your wheels and give off that burnt plastic smell. This may as well pre-wear out your tyres.
