The different possible roots and risks of smell of burnt plastic on a Bmw Serie 4 F32
So we start our guideline with the different possible roots of burnt plastic smell on a Bmw Serie 4 F32 . Generally speaking, noticing a plastic or rubber smell is hardly ever a good indicator. Obviously, modern vehicles are full of it and it could be the sign of a critical malfunction. Below we will review the different possible origins of burnt plastic smell:
- Transmission oil: This is the most important possible origin of such an odor. Obviously, 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 damaged, 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 auto parts and regulate the temperature as well, which will trigger the oil to overheat and thus give off that burnt plastic smell on your Bmw Serie 4 F32. 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 deteriorate 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 produce a strong smell of burnt plastic or rubber in the engine block of your Bmw Serie 4 F32.
- Faulty hose wear: This case occurs especially on Bmw Serie 4 F32 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 think will trigger 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 problem is the breakage of the accessory belt.
- A body component: Less basic, especially present on Bmw Serie 4 F32’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.
