The different possible sources and risks of smell of burnt plastic on a Peugeot 807

So we start our content page with the different possible sources of burnt plastic smell on a Peugeot 807 . In general, noticing a plastic or rubber smell is hardly ever a good sign. In truth, recent vehicles 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 most important possible source of such an odor. In truth, the function 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 function as a temperature regulator. However, in the long run, the oil will lose its performance and will not lubricate the auto parts and regulate the temperature as well, which will bring about the oil to overheat and thus give off that burnt plastic smell on your Peugeot 807. 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 completely 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 unit block of your Peugeot 807.
  • Defective hose wear: This case occurs especially on Peugeot 807 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 presume will bring about the plastic auto parts to wear out more quickly. Hoses are the first to be impacted 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 issue is the breakage of the accessory belt.
  • A body component: Less common, especially present on Peugeot 807’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.
