The different possible sources and risks of smell of burnt plastic on a Bmw Serie 4 F33

So we begin our article with the different possible sources of burnt plastic smell on a Bmw Serie 4 F33 . Generally speaking, noticing a plastic or rubber smell is hardly ever a good indicator. In truth, recent vehicles are full of it and it could be the sign of a major 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 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 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 parts and control the temperature as well, which will cause the oil to overheat and thus give off that burnt plastic smell on your Bmw Serie 4 F33. 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 specifically made 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 unit block of your Bmw Serie 4 F33.
  • Faulty hose wear: This circumstance arises specifically on Bmw Serie 4 F33 that are starting to get a few years old or that have stayed a long time without rolling. In fact, storing your vehicle unlike what you might presume will cause the plastic parts to wear out more fairly quickly. Hoses are the first to be affected by 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 common, specifically present on Bmw Serie 4 F33’s that have suffered a small shock. Following a front or rear impact, wheel arches, bumpers or other plastic body 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.
