AUDI

MOST COMMON  FAILURES FOR AUDI CARS: 

 Audi is a German automobile manufacturer that produce, designs, engineers, markets and distributes branded vehicle produced in nine production facilities worldwide. 

 Audi origins takes us back to the early 20th century when August Horch and 2 others manufacturers founded Auto Union, in 1932.                                                        In 1960, Auto Union was acquired by Volkswagen from Daimler Benz and the AUDI F103 series was the model that was first introduced to the public, when in 1965 the AUDI brand was relaunched. 

 From that day till today AUDI has become a strong presence on the automobile market constantly launching new models of cars in today's post I will like to make a list with the most common failures which German Experts Service Center engineers are mostly seeing

- COOLANT LEAK -

Water pump is the heart of the cooling system and leaks are the most common signs of a water pump failure. If the water pump starts leaking, the cooling system will lose coolant and ignoring this issue, might lead to engine overheat that will damage the engine cylinder head and cylinder head gasket

- OIL COOLER LEAK AND COOLANT MIXED WITH OIL –

A common problem meet in Audi cars is oil leaking and it might happen because of engine gaskets or seals or from the oil cooler adapter. Diagnosis is required and an action should be taken as this failure can severely damage your engine.

- ENGINE MOUNTING LEAK AND ENGINE VIBRATION –

Engine mount function is to hold the engine in place and also to reduce the engine vibrations felt inside the car. Engine mounts are made with a rubber material which might get damaged and break.

If you experience an unusual vibration inside your car it might indicate a problem with the engine mount.

- TURBOCHARGER FAILURE – AUDI

Turbocharger function is to force air into the combustion chamber and make the vehicle more powerful.

If you are experiencing any of this signs with your Audi car you might have a turbocharger failure:

  • Lack of acceleration
  • Excessive of irregular exhaust
  • Check engine light
  • Loud shrieking noise

- BROKEN SUSPENSION BUSHES –AUDI

The function of the bushes is to absorb the shock of turbulences when the car is moving. Worn bushes will affect the comfort and even the safety of the passengers inside the car.

Signs of damaged bushes:

  • Noises when the car is driven over gravelly roads
  • When you make sharp turn or hit the brakes will sound as the car is clunking
  • Steering is difficult to handle or feels looser than before.

- COOLANT VALVE LEAKS –

Coolant valve is one of the thermostat components and mainly is getting clogged and later brakes causing leaks that reach to the engine control unit causing costly damages

- TRANSMISSION PROBLEMS –

This is a common problem encountered mostly for the Audi A4 and Audi A6 and you should read and stay alert to take action at the right time:

- TORQUE CONVERTER- 

When the car becomes a few years old, the torque converter of the Audi A4 and A6 mostly will start having some failure symptoms as:  

  • Check Engine Light On – The ECU will turn on the engine warning light because it detects inconsistences between the RPMs of the engine and the transmission input shaft. Also the RPMs can become unstable when you accelerate
  • Needle Bearings are used to reduce friction of a rotating surface and if you hear any grinding sound while driving your car you should have your Audi’s checked for a torque related problem. Be aware that worn out bearings can destroy the transmission. 

- SLOW RESPONSE FROM THE GEARBOX –

This is a common problem of the Audi A6 transmission. The A6 models have CVT, automatic and multitronic gearbox if the gear shifting feels strange or hesitant during driving it might be a software issue or if it’s a high-mileage car you might also need to replace the transmission.

- LOW FLUID LEVELS -

A low fluid level of the transmission it’s problematic for any car and for Audi this is a common one.

If the gear slips during shifting or moves slower hat before, check the fluid level and if it’s low it might be a faulty seal in the driveshaft or gearbox from where the fluid leaks.
