Engines

The most widely used versions with a 2-liter gasoline turbo engine.

Typical malfunctions – premature stretching of the timing chain and an increase in oil consumption – are characteristic, first of all, for the 2.0 TFSI generation gen.2. In 2013 the engine was upgraded (generation gen.3), and the problem of early chain stretching and excessive oil consumption was eliminated.

It is not uncommon to get rid of increased oil consumption after replacing the oil separator with a modernized one. Moreover, a faulty oil separator leads to unstable idling and a drop in traction.

After 100,000 km it falls on the ignition coils.

Soon, with the advent of cold weather, the engine warm-up slows down in cars with S-tronic. The engine and the “robot” have one cooling circuit. The culprit is the box thermostat.

Occasionally, it is necessary to repair the turbine, or rather, the actuator.

The base 1.4 TFSI was released in 2014. There are no serious complaints about the engine from the owners of the Audi Q3 yet.

There are no complaints about the 2-liter diesel engine either. According to the experience of using the unit in other models of the VAG concern, the first problems arise only after 300,000 km.

The 2.0 TDI received a timing belt drive. The regulation prescribes its replacement every 150,000 km. Along with the belt, mechanics are advised to update the pump, which can leak.

Gearboxes

The base cars with the weaker 2.0 TDI (140 hp) and 1.4 TFSI (since 2014) had front-wheel drive and a 6-speed manual gearbox.

The 2-liter TFSI and more powerful TDI relied on a 7-speed S-Tronic robotic gearbox and a Quattro all-wheel drive system. For a surcharge, S-tronic was also installed in a pair of 1.4 TSI, but 6-speed.

The 7-speed S-tronic is LUK’s DQ500 dual clutch transmission. This version of the “robot” is considered one of the most successful. However, malfunctions occur, although not too often.

In the cars of the first years of production, noise was observed when shifting gears. At first, official services replaced the mechatronics, and then Audi recommended simply updating the box ECU firmware.

Sometimes mechatronics required intervention. For example, I had to change the solenoids.

The S-tronic clutch usually lasts a long time. A dual-mass flywheel will require additional costs.

The robot needs periodic renewal of the working fluid. This requires 6 liters of oil.

In the proprietary Quattro system, the Haldex electronically controlled multi-plate clutch of the 4th generation, and after restyling – the 5th generation, plays a decisive role.

Sometimes the clutch fails after 150-200 thousand km. Usually, its performance can be restored after replacing the control valve.
