Audi A5 Problems: 6 Most-Known Issues (Explained)

The Audi A5 is the classier version of the Audi A4 and is available in the convertible, coupe, or 4-door Sportback form.

However, there are various problems associated with the Audi A5, and we are here to list them one after the other.

Some of the common issues with the Audi A5 include transmission problems, excess oil consumption, and timing chain problems, among others.

Also, here are the best and worst Audi A5 years.

1. Transmission issues

The transmission problem is the most severe issue facing most Audi A5 owners, and it could be traced to the CVT Multitronic gearbox.

The gearbox has earned a notorious reputation as the worst automatic gearbox from Audi.

This problem arises when the transmission fluid is not changed when due. In some new Audi A5 vehicles, transmissions are somehow slow.

In some cases, the S-Tronic dual-clutch box performs poorly at lower speeds, and this is a major headache for most drivers.


2. Cooling system issues

The Audi A5 vehicles tend to leak when experiencing low coolant levels.

The models with 3.0L TDI are faced with this problem and the models with 3.2L petrol engines are not exempted because of coolant pump failure.

However, it is advisable to check your temperature gauge and coolant levels regularly to prevent this issue.

Failure to check your coolant levels may cause harm to your engine.

3. Airbag Failure to Deploy

A defective clock spring or passenger occupancy sensor may trigger the airbag lights of the Audi A5.

Oxidation on the connecting cable of the airbag control unit may cause corrosion of the unit.

If there is an issue with the Supplemental Restraint System, the airbag light may stay on and may cause the airbags not to deploy in case of an accident.

You can fix this issue by taking your vehicle to a competent mechanic to address the problem.

4. Electrical Glitches and Failure

This issue can be triggered by several reasons, and these include:

A defective battery sensor is responsible for the abrupt showing of warning lights on the dashboard, and this significantly affects the overall performance of the battery.

The failure of the alternator can cause engine stalling and battery discharge.

Several important components, such as the taillights, headlamps, and other exterior lights can malfunction, thereby making it hard to drive at night.

On the other hand, software issue failure can mess up your vehicle electronics, such as the instrument cluster and infotainment system.

It is crucial to ensure the proper maintenance and servicing of your Audi A5 to minimize the risk of electrical failures.

Using premium parts and engaging the services of licensed technicians can also prevent some of these problems.

5. Busted Timing Chain Issues

The Audi A5 has a timing chain system that can be affected by tensioner and guide issues.

Once the timing chain is stretched, it results in misfires while in motion when the pistons and valves are out of place.

This problem needs to be addressed quickly to prevent permanent damage to your engine.

6. Engine Issues

The engine is an integral part of any vehicle, and if the engine has problems, it will affect everything.

However, some of the problems associated with the Audi A5 engine are

  • Excessive oil consumption
  • Turbocharger failure
  • Engine warning light, and
  • Engine stalling

When there is an issue with the Audi A5 engine, it is likely to consume more oil at a faster rate than the normal one, and this will result in low oil levels and could damage the engine.

On the other hand, the turbocharger is an essential part of the car engine that enhances efficiency and performance.

In some cases, the turbocharger may fail without notice and affect the overall performance of the vehicle.

Audi A5 engines may suddenly stop while in motion, and problems with the fuel system cause this. It could be a severe problem if not addressed on time.

If there is a problem with the emissions system and other components of the engine, the engine warning light may illuminate.

These aforementioned problems can be resolved by proper maintenance, including prompt repairs and regular oil changes.
