The different possible sources and risks of smell of burnt plastic on a Mercedes Benz GLC Class

So we start our content page with the different possible sources of burnt plastic smell on a Mercedes Benz GLC Class . In general, noticing a plastic or rubber smell is hardly ever a good signal. In fact, modern vehicles are full of it and it could be the sign of a significant breakdown. 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. In fact, the objective of gear or transmission oil is to lubricate the different elements of your gearbox so that all the gears and pinions are not broken, it also has a second objective as a temperature regulator. Nevertheless, with time, the oil will lose its performance and will not lubricate the parts and regulate the temperature as well, which will cause the oil to overheat and thus give off that burnt plastic smell on your Mercedes Benz GLC Class. 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 principally done of rubber, will decline and no longer rotate completely on its axis. With the friction that this will cause 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 Mercedes Benz GLC Class.
  • Defective hose wear: This case arises specifically on Mercedes Benz GLC Class 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 think will cause the plastic 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 melt. The risk of this issue is the breakage of the accessory belt.
  • A body component: Less common, specifically present on Mercedes Benz GLC Class’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.
