“IGNORE your car's moans and groans at your own peril,” says Les McMaster, chairman Motor Industry Workshop Association.

Cars can make a cacophony of sounds. While some sounds are normal and many harmless, some need immediate attention.

• Grinding in the engine: this isn't necessarily your engine. It could be your front brakes.

• Any sound when turning a corner: likely to be connected to your steering column that could be damaged or needs to be replaced.

• Grinding gears: the clutch is either worn or needs to be adjusted. It can also indicate a more serious problem with the transmission.

• Knocking: if it's a knocking noise from deep inside the engine, it's usually not a good sign.

It could be your rod bearings which are worn out or loose and on the verge of failure. Contact a workshop immediately and get the noise properly diagnosed.

• Squealing when you accelerate: you won't miss this high-pitched noise and it's more than likely your fan belt is loose. It may also be worn through and need to be replaced.

• Hissing under the bonnet: you'd usually hear this when you switch the car off. It could be an oil or coolant that is leaking onto a heated engine part or the engine could be overheating.

• Loud bang while driving: if your car is backfiring it means the air and/or fuel mixture is too rich or the catalytic converter isn't doing its job.

• Rattling under the car: your exhaust system or brake pads could be loose.

• Roaring as you accelerate: check your exhaust system first as it could be damaged. Transmission issues could also be to blame.

• Scraping and grinding when you brake: your brake pads need to be replaced because they're now metal on metal and every time you hit the brakes you're doing damage to your car.
