The different possible sources and risks of smell of burnt plastic on a Bmw Serie 5
So we start our content with the different possible sources of burnt plastic smell on a Bmw Serie 5 . Generally, noticing a plastic or rubber smell is never a good sign. In actual fact, 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 source of such an odor. In actual fact, the objective 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 also has a second objective as a temperature regulator. Nevertheless, over time, the oil will lose its effectiveness and will not lubricate the auto parts and control the temperature as well, which will bring about the oil to overheat and thus give off that burnt plastic smell on your Bmw Serie 5. 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 mainly done of rubber, will deteriorate and no longer rotate entirely on its axis. With the friction that this will bring about 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 Bmw Serie 5.
- Defective hose wear: This case happens specifically on Bmw Serie 5 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 presume will bring about 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 issue is the breakage of the accessory belt.
- A body component: Less basic, specifically present on Bmw Serie 5’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 also pre-wear out your tyres.
