In this article, we explain the most common Audi 1.4 TFSI engine problems and provide tips on how to deal with them.
Audi 1.4 TFSI engines have a great reputation for being reliable and fuel-efficient, but like any engine, it has known common problems. If you own a car with this engine or are looking at buying one that does, it is important that you know what to do if the engine starts to malfunction.
The 1.4 TFSI engine is most commonly used in the A1, A3 and A4 models. This powerplant is perfect for powering these smaller-sized Audis efficiently.
What Does TFSI Stand For?
Fuel Stratified Injection with Turbocharging. In other words, TFSI is an abbreviation for a series of gasoline engines that have a small number of cylinders and high efficiency, which is now required by law. Audi, along with BMW and Mercedes Benz, are the industry leaders in this area.
It is worth noting that they distinguish themselves from the competition by employing an injection system with two operating modes: one that prioritises fuel economy, resulting in increased mileage, and another that strives to provide an increase in performance, resulting in more robust acceleration.
Since these engines have been accessible for quite some time, the moniker has gained widespread acclaim and usage. However, it is always possible to have reservations about the issues below.
Is the Audi 1.4 TFSI Reliable?
In general, the Volkswagen group, which includes the German brand Audi, is renowned for its reliability and high level of quality. Generally speaking, owners have only reported standard issues, none of which, according to the data, can be resolved by performing routine maintenance activities on a timely basis.
It is possible that the smaller engine size, the turbocharger, and, in some cases, cylinder deactivation of the TFSI family will cause some potential owners to be concerned about the costs of maintaining those engines over time.
As a result, if you don’t neglect the engine’s maintenance, the only thing you’ll have to worry about is finding a good road to take advantage of your Audi model, as they are typically among the best cars available in their respective market segments when they are kept in proper working order.
Common Audi 1.4 TFSI Issues
We hope that by listing common issues, you will be able to make a more informed comparison with any other TFSI models you may be considering and gain a better understanding of which new or used Audi vehicle is the most appropriate for you.
Excessive use of Oil
One of the most common Audi 1.4 TFSI engine problems is excess oil consumption. Your Audi is using oil at a far greater rate than predicted, requiring you to change it on a much more regular basis than anticipated. In general, if you want to minimize your car’s operating expenses, you should constantly maintain everything in the oil system in good working order.
Solutions that could be considered
It is possible that the piston rings in each cylinder are the source of the problem. The most common reason for this is that they are worn out from years of use. Replace them with new ones and the issue should be resolved. With the use of 5W-30 synthetic engine oil the Audi TFSI engine is more efficient.
Additionally, you should never rule out the potential that the oil tank has leaks, which are often caused by impact damage.
The next step is to inspect the pipe system for leaks. Despite the fact that they are less susceptible to impacts, they may be deteriorated or simply worn out through constant usage.
Engine tinkling sounds
A characteristic high-pitched tinkling noise may be heard coming from the inside of the front end of the vehicle when travelling.
No matter whether they are petrol or diesel engines, vibration is an unavoidable characteristic of all internal combustion engines. Intense and/or particular ones, on the other hand, are cause for concern.
Solutions that could be considered
It is likely that the timing chain has been strained, which is very prevalent in older vehicles. In actuality, this issue may even have an impact on the amount of power the vehicle produces; nevertheless, it may be resolved by simply changing the chain. You may want to get this issue resolved as soon as possible, a snapped chain can cause irreversible engine damage.
Black smoke from the exhaust
During the course of driving your Audi, you may observe a large amount of black smoke emanating from the exhaust pipe. It is common for this problem to occur in conjunction with a reduction in available horsepower and an increase in oil consumption.
Solutions that could be considered
While there are a variety of issues that can result in black smoke, it is common for the Audi TFSI engine to experience a problem with the turbo housing. If such is the case, you will need to repair the housing on your vehicle. This may include a replacement turbocharger or a refurbishment depending on the extent of wear.
Despite the fact that both the TFSI and TDI engine lines employ turbochargers, it is noteworthy to note that the diesel engines are not often impacted by this problem.
Failure of the turbocharger
Once again, TFSI engines are more prone than other engines to have this problem. Symptoms can include black smoke from the exhaust, a whistling noise coming from the top of the engine and a notable drop in horsepower. They are all indicative of a turbocharger issue.
Solutions that could be considered
Whether your car’s turbo requires a simple repair or a complete replacement, this operation is typically costly, even for the cheaper vehicles. If your vehicle is within 3 years old your manufacturer’s warranty should cover this. Aftermarket warranties can also cover turbochargers depending on the level of cover given.
Failure of the Ignition Coil
Another of the Audi 1.4 TFSI engine problems is ignition coil failure. These engines suffer from a high rate of ignition coil faults which can be a considerable annoyance. The ignition coils are very important in the combustion process. Essentially, the ignition coil takes the energy from the battery and uses it to generate a spark that is passed to the spark plugs, which ignites the fuel in the car. It is possible that your car may misfire if these components are not operating correctly.
Ignition coils are expected to last up to 100,000 miles, whereas spark plugs are expected to last between 30,000 and 60,000 miles on average.
Solutions to be considered
To be on the safe side, when one spark plug or ignition coil fails, we recommend replacing them all at the same time. This will prevent you from having to worry about worn parts being mixed in with new parts. For the DIY mechanics reading, get your required parts from The Green Spark Plug Company.
Engine slow to warm up
This issue is exactly what it sounds like: the engine takes a very long time to warm up. It affects both the EA111 and the EA211. When we say anything “takes a long time,” we’re referring to 10 – 15 minutes. After a little investigating, it was discovered that this issue continues to exist as a result of the way the engine was constructed. Because the 1.4-litre engines are smaller in size, they have a lower displacement, which results in less heat being generated in the process. Unfortunately, there isn’t much that can be done to ease this issue, which is something that is inherent to the 1.4s.
Solutions to be considered
It can be recommended that you start your car 10-15 minutes before you need to depart so that it has enough time to warm up. It is important to note that if the engine is not operating at its ideal temperature, it should not be pushed, as this might result in engine damage.
