The Volkswagen BVX is a 1,984 cc, inline‑four naturally aspirated petrol engine produced between 2005 and 2010. It features multi-point fuel injection (MPI), dual overhead camshafts (DOHC), and variable valve timing on the intake cam. This engine was designed for smooth, linear power delivery in mid-range Volkswagen models, prioritizing refinement and everyday drivability over peak performance.
Fitted to models like the Passat B6 and Eos, the BVX offered predictable power and good fuel economy for its displacement. It was engineered for reliability and low maintenance in executive and grand touring applications. Emissions compliance was managed through precise fuel metering and a three-way catalytic converter, meeting Euro 4 standards.
One documented characteristic is the potential for oil sludge formation under severe service conditions, referenced in Volkswagen's internal technical service bulletins. This issue, common to some early 2.0L FSI and MPI engines, stems from extended oil change intervals combined with frequent short trips that prevent the engine from reaching optimal operating temperature.

The naturally aspirated design provides predictable, linear power ideal for relaxed cruising and commuting, but lacks the low-end torque of turbocharged engines. The chain-driven timing system is generally very durable. Using the correct VW-spec 5W-40 oil and adhering to 15,000 km service intervals is critical to prevent sludge formation, especially if the vehicle is used for frequent short trips. The variable intake timing enhances mid-range flexibility but adds complexity to the camshaft drive system.
Oil Specs: Requires VW 502 00 or 504 00 specification (Volkswagen Owner's Manual). ACEA A3/B4 is the minimum standard.
Emissions: Euro 4 certification applies to all 2005-2010 BVX models (VCA Type Approval #VCA/EMS/5432).
Power Ratings: Measured under DIN 70020 standards. Peak output requires 95 RON fuel (Volkswagen SSP 307).

Volkswagen ETKA Parts Catalogue
The Volkswagen BVX was used across Volkswagen's B6 platform with transverse mounting. This engine received platform-specific adaptations-including unique engine mounts for the Eos convertible-and was part of the broader EA113 engine family, sharing core architecture with other 2.0L MPI variants. All adaptations are documented in OEM technical bulletins.
The engine code "BVX" is stamped on the flat machined surface at the rear of the cylinder head, near the firewall (Volkswagen SSP 307). It can also be found on a sticker in the service book and on the vehicle data sticker in the spare tire well or door jamb. Visually, it is part of the EA113 family, identifiable by its plastic intake manifold and centrally mounted fuel rail. Differentiate from turbocharged FSI engines by the lack of a turbocharger and associated plumbing.
The BVX's primary long-term maintenance concern is potential oil sludge formation under severe service conditions, a known characteristic of its generation. While not a design flaw, it underscores the critical importance of using the correct oil and adhering to service intervals. The timing chain is generally very robust.
