Complete Engines for Audi A4

Audi A4 Complete Engines

It almost goes without saying that the engine is the most important part of the Audi A4 or any other premium automobile for that matter. It is the source of energy that runs the Audi, with no fewer than five valves per cylinder and 155 pounds-feet of torque. Whether you drive a classic front-wheel-drive A4 or a quattro permanent four-wheel-drive model, your Audi A4 complete engine may need to be replaced or rebuilt.

The lifespan is entirely dependent on the amount of service and maintenance you dedicate to it. However, it is possible to drive over 200,000 miles before there is a need to have it changed or repaired. Regular change of oil, an efficient cooling system, and modest driving habits all contribute to a longer lasting engine.

There are a couple of signs that will indicate the need to replace or rebuild the entire engine. These signs may be catastrophic or pass without suspicion, but under the hood, the damage is already done. They include:

• Presence of metal flakes in the coil: If you discover tiny metal particles while replacing the oil, it is a sign that metallic parts of the system are grinding against each other, each time getting weaker and weaker. Despite sufficient lubrication, the metal flakes will keep forming.
• Knocking sound: Most drivers have experienced a knocking sound coming from their vehicles. The noise may not always be from the engine, but it could be the source. It occurs when the bearings wear out and no longer offset friction between moving parts. The wear and tear is a result of poor lubrication or long use.
• White smoke emanating from the exhaust: If you notice this white smoke, it means some of the burning gasoline has mixed with oil, thus producing the smoke that traveled all the way to the exhaust.

There are many factors to consider before you choose a diesel or standard gas engine to purchase. Depending on the year of manufacture, the Audi A4 will likely have a 2.8L V6, 1.9L TDI, or a 3.0L V6 TDI. Therefore, it is necessary to check the existing parameters before choosing the replacement. Each of these has different power output, varying from 100 to 148 brake horsepower. They also differ in the consumption rate. With the help and advice of a mechanic, you can interchange them and still maintain the performance of your original Audi A4.

Most Audi A4 sedans are turbo enabled, commonly called turbocharged fuel stratified injection or TFSI. This will give the vehicle the much-needed boost as well as a sporty performance. You need to confirm whether the one you are acquiring is turbocharged. The kind of fuel used is another factor to consider as you cannot exchange a gasoline for a diesel engine in your Audi.
