Indeed, modern cars are full of it and it could be the sign of a major 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. Indeed, 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 also has a second function as a temperature regulator. Nevertheless, as time passes, the oil will lose its efficiency and will not lubricate the parts and regulate the temperature as well, which will trigger the oil to overheat and thus give off that burnt plastic smell on your Audi Rs5. 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 mainly done of rubber, will decline and no longer rotate totally on its axis. With the friction that this will trigger the plastic will heat up and burn out, this reaction will generate a strong smell of burnt plastic or rubber in the engine block of your Audi Rs5.
  • Defective hose wear: This case arises specifically on Audi Rs5 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 believe will trigger 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 Audi Rs5’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 also pre-wear out your tyres.
