When it comes to vehicle odours, they are often signs of more serious problems with your car so any smell should be checked promptly. Here are some of the common types of smells you may notice within your vehicle and the issues that are associated with them.

A Burning Smell

A waft of burnt rubber or burnt plastic may be due to several different problems, most often it is the result of two surfaces rubbing together. Common causes of a burning smell include:

• A worn-out clutch – If the smell is similar to burning paper and you notice it becomes worse when shifting gears, your clutch may need replacing.
• An electrical short – In the event of a short circuit, the plastic around the wires can burn which will lead to a burnt plastic smell. In this instance it’s essential to locate the electrical fault quickly.
• The heater – if you notice a burning smell when you turn your heater on, especially after a long period without use, there may be a built-up of dust or debris in the vent. The heater can also cause a burning odour from leaking antifreeze or even from the heater core melting.
• Worn-out brakes – A seized calliper piston in your brakes can cause a burning smell when driving. If it’s only temporary, it may not be cause for concern, but if you notice it frequently then you should have your brakes examined.
• Oil leaks – An oil leak can drip into the exhaust while driving, causing a burning smell when you get out of the car.

A Musty or Stale Smell

If you notice a smell that’s vinegar-like or musty, it usually means there’s a build-up of mould in the depths of your air-conditioning system. This can often be rectified by running the fan on high for a period of time to dry out the system. If the smell persists, it may be due to clogged or dirty filters, or a faulty drainage system. When the drainage system isn’t functioning properly, mould can grow after water drippings overflow and the air conditioner spreads the moisture throughout the air.

A Smell Like Rotten Eggs

A rotten egg odour can mean a serious problem. The rotten egg smell is Sulphur, and it naturally occurs in fuel. It is converted into an odourless compound when combusted and after going through the car’s emission control system. The smell will likely by caused by one of the below issues:

• A faulty catalytic converter – The catalytic converter neutralizes emissions into harmless gases. When the converter malfunctions, it can emit harmful Sulphur gas.
• A transmission fluid leak – When transmission fluid leaks beyond the transmission system, you will notice an unpleasant eggy smell.
• Issues with the fuel pressure sensor – A malfunctioning fuel filter or fuel pressure sensor can cause the catalytic converter to flood with oil, preventing it from working properly and resulting in it emitting an odour.

If your car smells like rotten eggs, you’re going to need professional car service. Joondalup locals can rely on Car Care for comprehensive vehicle servicing and repairs at affordable prices.

A Sweet Smell

A sugary or syrupy smell such as maple syrup may indicate that your car is leaking coolant or antifreeze. This is a serious problem because a significant leak left untreated can cause your vehicle to overheat and can even result in total engine failure. Whilst any smells should be taken seriously, a sweet smell that lingers around should be seen to by a qualified mechanic as soon as possible. Total engine failure is catastrophic and will mean thousands of dollars in repairs.

While car deodorisers and air freshers may mask an unpleasant smell, it’s best that you don’t ignore it. The smell is likely a sign of a bigger issue that if left undetected, can result in expensive repairs down the track.
