The Q5L engine is an EA888 model engine, produced by Volkswagen FAW Engine (Dalian) Co., Ltd., and is a domestically manufactured engine. The Q5L engine model is EA888-DKU. The high-power version has a maximum power of 185 kW and a maximum torque of 370 Nm. The low-power version has a maximum power of 140 kW and a maximum torque of 320 Nm. For daily maintenance of the Q5L engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication area, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from component wear to form sludge. In small amounts, it remains suspended in the oil; in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

The Audi Q5L indeed uses the EA888 engine, which I can confirm with certainty. This 2.0T engine is a flagship model of the Volkswagen Group and has been employed since the domestic Q5L's launch in 2018. The third-generation EA888 is installed in both the 40TFSI and 45TFSI variants, with the low-power version delivering 190 horsepower and the high-power version offering 252 horsepower, demonstrating commendable performance in both power output and fuel efficiency. The latest models have been upgraded to the fourth generation, utilizing dual injection technology to optimize combustion efficiency. However, it's important to note that the hybrid 55TFSIe is also based on a modified EA888. This engine features a compact design, but requires regular cleaning to address carbon buildup issues.

I drove my friend's Audi Q5L and specifically asked about the engine model, confirming it's the EA888. It comes in high and low power versions, and the 40TFSI is more than sufficient for daily driving, with plenty of power for highway overtaking. The third-generation engine has resolved the previous oil consumption issue, and maintenance requires 5W-40 full synthetic oil. The newer models switched to the fourth generation, making start-stop smoother, but the turbo's position changed during repairs, making disassembly and assembly more troublesome. Additionally, when buying a used car, be cautious about the timing chain tensioner issue in early 2018 models.

The Q5L comes standard with the EA888 engine across all variants. The currently available models are equipped with the fourth-generation version, featuring an integrated exhaust manifold design to reduce turbo lag and dual VVT for optimized fuel consumption. Paired with a 7-speed dual-clutch transmission, it achieves a 0-100km/h acceleration time of 6.9 seconds. Compared to BMW's B48 engine, the EA888 delivers torque earlier, producing 370N·m at just 2000 rpm. Long-term use requires attention to the cooling system's sealing, as water pipe joints are prone to leakage.
