The different possible roots and risks of smell of burnt plastic on a Renault Grand Modus

So we begin our article with the different possible roots of burnt plastic smell on a Renault Grand Modus . Generally, noticing a plastic or rubber smell is hardly ever a good signal. Indeed, recent cars are full of it and it could be the sign of a critical malfunction. Down below we will review the different possible origins of burnt plastic smell:

  • Transmission oil: This is the main possible source of such an odor. Indeed, 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 broken, it as well has a second action as a temperature regulator. However, with time, the oil will lose its effectiveness 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 Renault Grand Modus. 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 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 produce a strong smell of burnt plastic or rubber in the engine block of your Renault Grand Modus.
  • Faulty hose wear: This circumstance happens specifically on Renault Grand Modus that are starting to get a few years old or that have stayed a long time without rolling. In fact, storing your car unlike what you might believe will trigger the plastic parts to wear out more fairly quickly. Hoses are the first to be suffering from 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 basic, specifically present on Renault Grand Modus’s that have suffered a small shock. 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. This may as well pre-wear out your tyres.
