Knowing what different smells can signal can help you to diagnose the issues before you take your car to an auto mechanic.
Modern cars do not contain much timber. However, if you are out driving and you smell burning timber, this could be a sign that your brake pads are failing. Over time, the friction of the wheel against a brake pad will cause it to wear down. As the brake becomes thinner and overheats, it can begin to generate a burning timer smell.
Sulphur has a very distinctive odour which is often described as smelling like rotten eggs. If you smell this scent while out driving, this could indicate a problem with the battery or catalytic converter on your vehicle. If your battery is overcharged, it may begin to emit a strong sulphur smell. You should have the battery inspected by a qualified mechanic who will be able to replace it if need be. If the catalytic converter on your car's exhaust system becomes blocked, fumes may build up within your car, causing a sulphur smell. You should have the exhaust system inspected and cleaned at your local auto shop.
If your car begins to smell of mould, it is the likely source of the problem will be the vehicle's air conditioning system. Over time, moisture and microbes can build up on the surface of the filters within the air con system, causing mould and mildew to develop. The smell of this mould will be circulated around your car every time you use the air conditioning system. If you smell mould, you should ask an auto mechanic to clean the air conditioning system.
