The different possible sources and risks of smell of burnt plastic on a Mercedes Benz GLS Class
So we begin our content with the different possible sources of burnt plastic smell on a Mercedes Benz GLS Class . Generally, noticing a plastic or rubber smell is never a good signal. Obviously, recent vehicles are full of it and it could be the sign of a important malfunction. 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. Obviously, the action of gear or transmission oil is to lubricate the different components 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, in the long run, the oil will lose its efficiency and will not lubricate the auto 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 Benz GLS 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 made 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 create a strong smell of burnt plastic or rubber in the engine unit block of your Mercedes Benz GLS Class.
- Faulty hose wear: This case occurs especially on Mercedes Benz GLS Class that are starting to get a few years old or that have stayed a long time without rolling. In fact, storing your car contrary to what you might think will trigger the plastic auto parts to wear out more fairly 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 might melt. The risk of this problem is the breakage of the accessory belt.
- A body component: Less basic, especially present on Mercedes Benz GLS Class’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.
