The Volkswagen EA888 Gen 4 is a 1,984 cc, inline‑four turbocharged petrol engine introduced in 2019. It features a dual — injection system (port and direct), integrated exhaust manifold, and variable valve timing on both camshafts. In standard applications it produces 140–228 kW (190–310 PS) with torque ranging from 320–400 Nm, delivering responsive performance and improved thermal efficiency.
Fitted to models such as the Golf Mk8, Tiguan Mk2, Passat B8, and Audi A3/S…
All production years (2019–present) meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen EA888 Gen 4 is a 1,984 cc inline‑four turbocharged petrol engineered for compact and mid‑size VW Group vehicles (2019–present). It combines dual-injection (port + direct) with a fully integrated exhaust manifold and variable valve timing to deliver responsive power and low emissions. Designed to meet Euro 6d standards, it balances performance with regulatory compliance and drivability.

The Volkswagen EA888 Gen 4 was used across Volkswagen's Mk8/B8 platforms with transverse mounting and shared extensively within the Volkswagen Group. This engine received platform-specific adaptations—reinforced mounts in the Arteon and revised cooling in the Tiguan R—and from 2021 the Golf R adopted a 235 kW variant with enhanced oil cooling, creating minor interchange limits. Partnerships enabled use in Audi, Škoda, and SEAT models with identical core architecture. All adaptations are documented in OEM technical bulletins.
The EA888 Gen 4's primary reliability risk is high-pressure fuel pump (HPFP) wear under high thermal load, with elevated incidence in performance variants (Golf R, Tiguan R). Volkswagen internal data from 2022 indicated a measurable increase in HPFP-related warranty claims for vehicles with >30,000 km under aggressive driving, while UK DVSA data shows low emissions failure rates due to robust GPF/EGR design. Extended idling after hard driving and incorrect oil specification accelerate HPFP and turbo degradation, making fluid discipline critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The EA888 Gen 4 is significantly more reliable than earlier generations, with robust timing chains and improved thermal management. However, high-performance variants (e.g., Golf R) may experience HPFP wear if driven aggressively without proper cooldown. Using correct 0W-20 VW 508 00 oil and adhering to service intervals ensures long-term durability.
The main issues are high-pressure fuel pump wear (especially in hot climates or performance models), GPF clogging from short trips, turbo actuator faults, and coolant flange leaks. These are documented in Volkswagen service bulletins ST03‑21‑09 and TIS updates, not anecdotal reports.
It powers the Golf Mk8 (including R), Tiguan Mk2 (including R), Passat B8 (2020+), and Arteon (2020+). It's also used across the VW Group in Audi A3/S3 (8Y), Škoda Octavia vRS, and SEAT León Cupra. All meet Euro 6d emissions standards.
Yes. Stage 1 ECU remaps safely add +20–30 kW on standard hardware due to conservative factory calibration. Higher stages require upgraded intercooler, exhaust, and possibly HPFP. Tuning must preserve GPF regeneration logic to avoid emissions faults.
In a Golf 2.0 TSI 190 PS, expect ~7.2 L/100km (city) and ~5.1 L/100km (highway), or ~47 mpg UK combined. Performance models (Golf R) average 8.5–9.5 L/100km. Real-world economy depends heavily on driving style and GPF regeneration cycles.
Yes. Like all modern VW petrol engines, it is an interference design. If the timing chain fails (extremely rare in Gen 4), piston-to-valve contact will cause catastrophic damage. However, the chain is designed to last the engine's lifetime under proper maintenance.
Volkswagen mandates 0W-20 synthetic oil meeting VW 508 00 (for petrol) or 509 00 (for petrol with extended drain) specifications. Using older 5W-30 oils risks GPF clogging and voids warranty. Change every 15,000 km or 12 months.
