The different possible roots and risks of smell of burnt plastic on a Mercedes Classe B 2
So we begin our content page with the different possible roots of burnt plastic smell on a Mercedes Classe B 2 . Generally speaking, noticing a plastic or rubber smell is never a good indicator. In fact, modern cars are full of it and it could be the sign of a major breakdown. Down below we will talk about the different possible origins of burnt plastic smell:
- Transmission oil: This is the main possible origin of such an odor. In fact, the objective 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 objective as a temperature regulator. Nevertheless, in the long run, the oil will lose its effectiveness and will not lubricate the auto parts and control the temperature as well, which will cause the oil to overheat and thus give off that burnt plastic smell on your Mercedes Classe B 2. 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 principally done of rubber, will decline and no longer rotate totally 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 Classe B 2.
- Defective hose wear: This case happens especially on Mercedes Classe B 2 that are starting to get a few years old or that have stayed a long time without rolling. In reality, storing your car contrary to what you might believe will cause the plastic auto parts to wear out more quickly. Hoses are the first to be troubled by this phenomenon. The rubber will disintegrate little by little and with the rise in heat of the fluid that circulates in it, it might melt. The risk of this problem is the breakage of the accessory belt.
- A body component: Less basic, especially present on Mercedes Classe B 2’s that have suffered a small shock. Following a front or rear impact, wheel arches, bumpers or other plastic body auto parts that might have been bent might rub against one of your wheels and give off that burnt plastic smell. This may as well pre-wear out your tyres.
