Bring your Audi to Euro Car Clinic if the engine is making strange noises. Do this sooner rather than later because the engine noise could be assigned that the engine is being damaged while you are driving your Audi. You always want the Audi to purr like a kitten. If it starts making noises that it normally does not make, there is something wrong in the engine that requires our immediate attention.
Grinding or Growling
For example, if the engine is grinding or growling, you may have an oil circulation problem. If you continue to drive the Audi without motor oil circulating through the engine, you can damage it beyond repair. In addition to an oil problem, grinding or growling can also be caused by a faulty water pump.
Hissing or Sizzling
Figuratively you want your Audi’s engine to sizzle. If it is sizzling literally, you may have leaking auto fluid. The auto fluid will sizzle when it meets with hot engine parts. It may also hiss. Another thing that will make the Audi’s engine hiss is a leaking vacuum hose. This can also sound like suction.
Knocking
Knocking stands alone because it is the only sound that you will hear from your Audi’s engine if it is knocking. The things that make the engine knock or detonation problems and worn rod bearings. The latter can damage your cylinder block because the pistons can damage the cylinder walls.
Popping or Tapping
Four parts in the exhaust system will pop or tap if they are having problems. These parts are the catalytic converter, the exhaust manifold, the manifold gasket, or the muffler. In the case of the muffler, the sound will get much louder when you press down on the accelerator.
Rumbling or Roaring
The catalytic converter and the muffler can also rumble or roar if there is a problem. When it comes to the catalytic converter, your Audi’s engine will rumble and roar if it has been stolen. The Audi’s engine will also rumble and roar if there is a hole in the muffler.
Squealing or Squeaking
Finally, your Audi’s engine may squeal or squeak if the power steering pump needs to be replaced. In the case of the pump, you will hear the noise when you turn the steering wheel. In addition, the Audi’s engine will squeal or squeak if the accessory belt needs to be tightened or replaced.
