In truth, modern cars are full of it and it could be the sign of a important breakdown. Below we will review the different possible origins of burnt plastic smell:
- Transmission oil: This is the main possible origin of such an odor. In truth, 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 also has a second action as a temperature regulator. However, with time, the oil will lose its performance and will not lubricate the 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 Mercedes Classe B 3. 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 principally done of rubber, will decline and no longer rotate entirely on its axis.

Following a front or rear impact, wheel arches, bumpers or other plastic body parts that may possibly have been bent may possibly rub against one of your wheels and give off that burnt plastic smell.
