The different possible sources and risks of smell of burnt plastic on a Audi A8

So we start our article content with the different possible sources of burnt plastic smell on a Audi A8 . In general, noticing a plastic or rubber smell is never a good signal. In fact, recent cars 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 main possible source of such an odor. In fact, the action 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 action as a temperature regulator. Nevertheless, over time, the oil will lose its performance and will not lubricate the auto parts and control the temperature as well, which will trigger the oil to overheat and thus give off that burnt plastic smell on your Audi A8. 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 mainly done of rubber, will degrade 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 create a strong smell of burnt plastic or rubber in the engine block of your Audi A8.
  • Defective hose wear: This circumstance arises specifically on Audi A8 that are starting to get a few years old or that have stayed a long time without rolling. In reality, storing your vehicle unlike what you might think will trigger the plastic auto parts to wear out more fairly 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 possibly melt. The risk of this problem is the breakage of the accessory belt.
  • A body component: Less general, specifically present on Audi A8’s that have suffered a small shock. Following a front or rear impact, wheel arches, bumpers or other plastic body auto parts that may possibly have been bent may possibly rub against one of your wheels and give off that burnt plastic smell. This may as well pre-wear out your tyres.
