Buying a late-model Audi is a great way to enjoy exceptional German engineering and luxury without breaking the bank. One standard engine found in a variety of late-model Audis is the Volkswagen Auto Group EA888 turbocharged 4-cylinder, typically distinguished by the 2.0T moniker. This engine replaced the earlier EA113 motor found in some early 2000s vehicles.

This newer motor is generally reliable, but it does have its fair share of gremlins. Oil leaks are not uncommon, and learning to recognize some of the potential sources can help you to maintain your car better. Below you will find three types of oil leaks that develop on Audi A4s, A3s, TTs, and any other model that uses this engine.

1. Valve Cover Gasket Leaks

Leaks at the valve cover gasket are not uncommon, and they plague many German car models. The valve cover gasket seals the connection between the plastic valve cover and metal motor head. This gasket typically leaks when the heat from the engine hardens the rubber, allowing it to crack. Internal engine pressure can then push small amounts of oil through the gaps.

Valve cover gasket leaks are often relatively minor, and you may not notice any puddles of oil or significant losses. In some cases, the oil can drip onto parts of the exhaust, leading to a burning oil smell. Check for smoke near the rear of the engine bay or signs of dried oil along the side of the valve cover.

2. Camshaft Position Sensor Leaks

You can find the camshaft position sensor (CPS) for most models along the side of the engine toward the rear of the engine bay. Leaks from the sensor are usually the result of a failed gasket, and they can be fairly minor. In some cases, a failed positive crankcase ventilation (PCV) valve can increase internal oil pressure enough to push some oil past the CPS gasket.

Signs of a CPS leak may not be immediately apparent, but if you can access the sensor, then you can look for nearby oil stains. Watch for evidence of oil dripping farther down into the engine bay as well.

3. Oil Consumption

Unfortunately, some instances of oil loss are not the result of a leak at all. Some earlier models using the 2.0T engine can suffer from excessive engine oil consumption. Over time, this problem can grow worse and cause severe internal engine damage. If you are losing oil and cannot locate the source, then you may be suffering from this problem.

For suspected oil consumption problems, a qualified Audi technician like the ones at Hillside Imports can check your motor for proper compression and attempt to determine if the loss originates from another source. Whatever the ultimate cause, you should never ignore any loss of oil. If you find yourself topping your Audi off with oil regularly, always have your car inspected by an experienced mechanic.
