7 Signs Your Audi Needs Maintenance

Audi Needs MaintenanceDriving a luxury car like an Audi requires extreme attention to detail. These cars need a special type of maintenance to perform at their best.

As a car owner, you should be doing your due diligence to ensure your car is at optimal performance level. If not, you’re gonna have to dish out cash for serious repairs.

We’ve created this guide to show you the signs that your Audi needs maintenance.

1. You See Signals Flashing on Your Dashboard

Nowadays, cars have an electronic computer system that alerts you to a number of vehicle maintenance issues.

However, not everyone reads their driver’s manual. Some drivers have no idea what those flashing lights mean, and that proves to be very dangerous.

Especially when your Audi needs maintenance.

The first thing I suggest is to read the owner’s manual. It will tell you everything you need to know about the make, model, and computer system.

Audi employs a mileage-based system that alerts you to maintenance needs after you’ve driven X amount of miles.

Your manual should also include a standard maintenance schedule to keep you up-to-date with repairs.

Every car goes through wear and tear, and experts suggest a standard maintenance check after one year or 5,000 miles. After 5,000 miles, you need to change your oil and filter, check the brake system, and check/rotate tires.

2. Smoke

Smoke is always a bad sign. People usually panic when they see smoke and think the engine is on fire or the car might explode.

In truth, smoke usually signals a problem with the exhaust like a valve issue.

Believe it or not, smoke also ranges in color. Blue and gray smoke mean different things.

Smoke can also signal a bigger problem such as a blown gasket. Pay special attention to the color of the smoke.

Blue smoke means the engine is burning oil through the valve, piston rings, or spark plugs. If you have a turbocharged car, blue smoke means something is wrong with the turbocharger.

Gray Smoke

Gray smoke has a few different meanings. It could mean a transmission issue. The vacuum modulator could be malfunctioning and leaking fluid into the engine.

Gray smoke can also mean an issue with the PCV system. When the PCV valve isn’t operating properly, oil starts to leak.

White Smoke

White smoke suggests a significant problem with the vehicle. It could mean any of the following:

  • Coolant Leakage
  • Blown Head Gasket
  • Damaged Cylinder Head
  • Cracked Engine Block

Black Smoke

Black smoke always means an issue with the engine.Make sure your air filters, fuel injectors, and fuel-pressure regulators, and fuel return line is working properly.

3. Ignition Coil or Spark Plug Problems

Ignition coils and spark plugs are interconnected. The ignition coil powers the ignition which lights up your spark plugs. Ignition coil failure leads to an engine misfire.

Ignition coil failure is usually caused by excess heat, vibration, and voltage overload. Excess heat or vibration damage the windings and insulation in the coil.

Open spark plugs or plugs with an excessive resistance increase the coil’s output voltage levels. High voltage levels burn through the coil’s insulation and cause circuit shortages.

In extreme cases, the engine will not start or run.

4. Oil Leaks

An oil leak is a common car issue and your Audi needs maintenance if you notice oil puddles under your car.

The oil dipstick should tell you if the engine is in need of oil. Low levels mean your engine is leaking oil. You should also be on the lookout for blue smoke.

As we mentioned before, blue smoke is a sure sign of an engine issue.

If your engine is leaking oil, it’s probably caused by one of these four things:

  • Oil Seals
  • Degraded engine gaskets
  • Bad Connections
  • Oil pan leaks

Visit your mechanic right away once you identify a leak. Leaks can lead to engine failure. Typically, an Audi leakage problem is linked to the valve cover gasket or the camshaft tensioner.

5. Fuel Caps

The vehicle information display system should alert you to a loose fuel cap. This could be as simple as checking your gas tank and screwing the cap in or getting a replacement.

In addition to the fuel cap warning, the display system will also ignite the “check engine” signal. That’s because a loose fuel cap leads to low gas mileage.

6. Catalytic Converters

Although your catalytic converters are made to last for a decade, these problems can arise, causing you to need replacement converters for your Audi:

  • Contamination
  • Clogging
  • Overheating
  • Damage

Converter contamination is caused by gas with high levels of lead, engine coolant, and oil. Once the converter is clogged, it’s hard for exhaust gases to exit the vehicle.

When the exhaust system is compromised, oxygen can’t enter the system and the engine becomes slow.

Overheated catalytic converters are the result of a faulty exhaust valve or spark plugs that misfire. The defective valve or spark plugs make it hard for the Audi to properly burn gas.

Excess amounts of unburned gas create overheated catalytic converters.

Be on the lookout for smoke. Black smoke can be a sign of catalytic converter issues.

Other signs include the following:

  • Strong sulfur or egg smell coming from the exhaust
  • Slow engine performance
  • Overheated engine
  • Acceleration issues

7. Exhaust Gas Re-Circulation (EGR)

Exhaust gas recirculation is a system that takes a portion of the engine’s exhaust fumes and circulates it back into the intake air. By substituting burnt gas for oxygen, the system helps to reduce nitrogen oxide.

A valve is the mao component of the system that allows gas to flow through.

The system works within the combustion chamber to lower the cylinder temperature. Some cars are equipped with an EGR cooler, to cool the gas before it passes through the EGR system.

The biggest issue with EGR systems is carbon build-up.

When your EGR starts acting up, you’ll notice problems with your engine. Engine problems are a sure sign that your Audi needs maintenance.

Fuel efficiency and acceleration problems could be a sign that it times to check the EGR valves.
