EA888 engine oil-water separator failure can affect power performance, with symptoms including jerking sensations, commonly referred to as engine hesitation. Below is relevant information about the EA888 engine: 1. Displacement classification: The EA888 series engines come in two displacements: 1.8L and 2.0L. The 1.8TSI delivers a maximum power of 118kw (160PS) at 5000-6200rpm and a maximum torque of 250Nm at 1500-4500rpm; the 2.0TSI offers a maximum power of 147kw (200PS) at 5100-6000rpm and a maximum torque of 280Nm at 1700-5000rpm. 2. Introduction: The EA888 engine is a mainstay in Volkswagen Group's mid-to-high-end vehicle lineup, available in 1.8L and 2.0L displacements. It integrates advanced technologies such as direct fuel injection, turbocharging, and variable valve timing. With ample low-end torque, excellent fuel economy, and top-tier reliability, it has gained widespread market recognition. The EA888 engine adheres to globally unified technical specifications and quality control standards and is installed in various Volkswagen models, including the Magotan, CC, Tiguan, Passat, and Audi Q5.
A friend of mine drives a Volkswagen with the EA888 engine, and he told me the symptoms of a faulty oil separator are quite obvious. The main signs are unusually fast oil consumption—the oil level on the dipstick drops significantly every few thousand kilometers—and blue smoke coming from the exhaust with a strong odor. The engine feels sluggish, acceleration is sluggish, and it occasionally shakes badly at idle, though no warning light comes on. However, the problem worsens after long drives. This issue is quite common with the EA888 due to its design, which is prone to clogging. Excessive carbon buildup can damage the catalytic converter, leading to soaring repair costs. It's recommended to regularly check the dipstick, and if the oil level drops abnormally, replace the separator as soon as possible. After replacement, the car runs much quieter, and performance is restored. Delaying repairs can cause severe internal engine damage—saving a little money isn't worth it. Safety comes first.
