What is the normal negative pressure for the EA888 PCV valve?

[SiennaRose]

Negative pressure values between 8-20 are considered normal. Below is relevant information about the EA888: 1. Main engine model: The EA888 engine is the primary powertrain for Volkswagen Group's mid-to-high-end models, available in 1.8L and 2.0L displacements. It integrates advanced technologies such as direct fuel injection, turbocharging, and variable valve timing, earning widespread market recognition for its strong low-end torque, excellent fuel economy, and top-tier reliability. 2. Drawbacks: The EA888 series has three generations of products, with the second-generation EA888 engine being notorious for its design flaws, particularly oil consumption and leakage issues. Less severe cases may trigger the oil warning light at 7,000-8,000 km intervals requiring oil top-up, while severe cases may prompt warnings as early as 4,000-5,000 km or even 2,000-3,000 km.
