Short description Audi A3
The three-door hatchback Audi A3 appeared in 1996. It was based on the PQ34 platform. The car is equipped with airbags, stabilization system and climate control. Restyling of the Audi A3 took place in 2000. The release of the car in Germany ended in 2003, and in Brazil the car continued to roll off the assembly line until 2006.
The second generation was presented at the Geneva Motor Show in 2003. Initially, the car was sold only in the back of a three-door hatchback. In July 2008, a five-door version appeared. Since 2008, car owners have had the opportunity to buy an Audi in the back of a convertible. The Audi A3 car has been restyled several times, which took place in:
- 2005;
- 2008;
- 2010 year.
In March 2012, the third generation Audi A3 was presented at the Geneva Motor Show. The car had a three-door hatchback body. The production of the car started in May 2012, and sales started on August 24 of the same year. The five-door version of the car was presented at the Paris Motor Show. It went on sale in 2013.
In New York on March 26-27, 2013, the Audi A3 sedan was introduced. Its sales started at the end of May of the same year. In September 2013, the Audi A3 cabriolet was presented at the Frankfurt Motor Show. Restyling of the third generation took place in 2017. The changes affected the front of the car.
Overview of engines on various generations of cars
The Audi A3 uses a wide range of powertrains. It includes petrol, diesel and hybrid engines. All engines are able to provide the dynamics necessary for urban operation. You can get acquainted with the used power units in the table below.

Popular motors
On the first generation of the Audi A3, the AGN power unit gained popularity. It has a cast iron cylinder block. The motor is not whimsical to the quality of the poured gasoline. Its resource is more than 330-380 thousand km.
In the second generation, both diesel and gasoline ICEs were popular. The AXX engine was in particularly high demand. The motor was not used for such a long period of time. It served as the base for several of the company's other powertrains.
One of the most powerful engines is BUB. The engine has six cylinders and a volume of 3.2 liters. The power unit is equipped with a Motronic ME7.1.1 power supply system. The engine resource exceeds 270 thousand km.
The third generation of the Audi A3 was created with the utmost respect for the environment. Therefore, all bulky internal combustion engines were removed from the engine compartment. The most powerful and popular was the 2.0-liter CZPB. The engine operates on the Miller cycle. The motor is equipped with a combined FSI + MPI power supply system.
The third-generation Audi A3 and the 1.4-liter CZEA engine are popular. Its power is enough for comfortable operation of the car in urban conditions. At the same time, the engine shows high efficiency. The presence of the ACT system allows you to turn off a pair of cylinders during low loads.
Which engine is better to choose Audi A3
Among the Audi A3 of the first generation, it is recommended to make a choice towards a car with an AGN engine under the hood. The motor has a huge resource and does not bother with frequent problems. The popularity of the engine eliminates the difficulty of finding spare parts. At the same time, AGN is frisky enough for comfortable movement around the city.
Another good choice would be an Audi A3 with an AXX engine. The motor has a good resource, but subject to timely maintenance. Otherwise, a progressive maslozher appears. Therefore, when choosing a car with AXX, careful diagnostics are required.
For fans of high-speed and dynamic driving, the only right choice is the Audi A3 with a BUB engine under the hood. The six-cylinder unit produces 250 hp. When purchasing a car with BUB, the car owner should be prepared for a very high fuel consumption. Oil consumption on used internal combustion engines during dynamic driving can also be very high.
For car owners who want a newer and more powerful car, the Audi A3 with CZPB engine is the best choice. The motor meets all environmental requirements. Its power of 190 hp is enough for most car owners. CZPB is unpretentious in operation. At the same time, it is important to fill in only high-quality fuel.
For people who are concerned about pollution, the Audi A3 with CZEA engine is the best choice. The motor is very economical. The internal combustion engine has the ability to turn off two cylinders, which reduces the amount of fuel burned at low loads. At the same time, the power unit is very reliable and, with proper maintenance, does not present unexpected breakdowns.
Reliability of engines and their weaknesses
One of the most reliable engines is AGN. It rarely has serious damage. The weak points of the motor are mainly associated with its considerable age. Problems that appear after 350-400 thousand kilometers:
- contamination of nozzles;
- wedging of the throttle;
- floating revolutions;
- damage to the vacuum regulator;
- contamination of the crankcase ventilation system;
- failure of sensors;
- the appearance of vibration at idle;
- small oiler;
- the complexity of the launch;
- knocking and other extraneous sounds during operation.
Second generation engines are less reliable than earlier engines. Their margin of safety has decreased, the design has become more complicated and more electronics have been added. So, for example, the AXX power unit with relatively high mileage presents a number of malfunctions:
- large oiler;
- misfiring;
- soot formation;
- change in piston geometry;
- failure of the phase regulator.
Cars with BUB engines are usually used by car owners who prefer a sporty driving style. This creates a significant load on the motor and causes excessive wear. Because of this, the elements of the cylinder head are destroyed, compression drops, fuel consumption increases and an oil cooler appears. The engine has a fancy cooling system for two pumps. They often fail, which leads to overheating of the internal combustion engine.
The CZPB engine is produced recently, but even a short period was able to confirm its high reliability. It has no "childish" problems or noticeable design miscalculations. The weak point of the motor is the variable displacement oil pump. The water pump also shows insufficient reliability.
The main problem in CZEA engines is the two-cylinder deactivation system. It leads to uneven wear of the camshafts. The CZEA plastic pump is prone to leakage. After overheating, engines begin to suffer from oil burners.
Maintainability of power units
The power units of the first generation Audi A3 have good maintainability. Their cast iron cylinder blocks are subject to boring. On sale it is quite easy to find stock piston repair kits. Motors have a large margin of safety, so after the capital they get a resource close to the original. Engines of the second generation of cars have a similar, although slightly less maintainability.
The power plants of the third generation Audi A3 have sophisticated electronics and a design that is not particularly designed for repair. Engines are officially considered disposable. In case of serious breakdowns, it is more profitable to change them to contract ones. Minor problems are fixed very easily, as there are a fairly large number of auto parts on sale.
Tuning engines Audi A3
All Audi A3 engines are to some extent “strangled” from the factory by environmental standards. This is especially true of the third generation of cars. Chip tuning allows you to reveal the full potential of power plants. If you get an unsuccessful result, there is always the opportunity to return the firmware to the factory settings.
Chip tuning allows you to add only 5-35% of the original power. For a more significant result, intervention in the design of the motor will be required. First of all, it is recommended to use a turbo kit. With deeper tuning, pistons, connecting rods and other elements of the power plant are subject to replacement.
