The Volvo B 4204 T17 is a 1,948 cc, inline‑four petrol engine produced between 2000 and 2004. It features a cast‑iron block, dual overhead camshafts (DOHC), and a Mitsubishi TD04 turbocharger with an air-to-air intercooler. This forced-induction unit delivered approximately 170 hp (127 kW) and 184 lb‑ft (250 Nm) of torque, offering enhanced performance for Volvo's compact executive models.
Fitted primarily to the Volvo S40 and V40 models, the B 4204 T17 was engineered for responsive, sporty driving character. Emissions compliance was achieved through electronic fuel injection and catalytic converters, meeting Euro 3 standards for applicable markets throughout its production.
One documented service concern is premature failure of the turbocharger’s oil return line gasket, potentially leading to oil leaks and turbo bearing damage. This issue, highlighted in Volvo Service Bulletin 4204T17‑10, is often linked to heat degradation and material fatigue. The engine was succeeded by the B5254T2 and B5244T3 engines in subsequent model years.
Production years 2000–2004 meet Euro 3 standards for applicable markets (VCA UK Type Approval not applicable for pre-1992 vehicles).
The Volvo B 4204 T17 is a 1,948 cc inline‑four petrol engine engineered for compact sedans and wagons (2000-2004). It combines a robust cast-iron block with a modern DOHC 16-valve valvetrain and timing belt to deliver turbocharged performance. Designed to meet Euro 3 emissions regulations, it incorporated catalytic converters and precise electronic fuel injection.

The turbocharger provides strong low-end torque ideal for urban driving but requires strict adherence to the 60,000-mile timing belt replacement interval and regular inspection of the turbo oil return line gasket to prevent bearing damage. SAE 5W-30 oil is recommended. The Bosch Motronic system requires precise sensor function. Catalytic converter models mandate unleaded fuel. Ignition timing and boost pressure are critical for performance and emissions.
Oil Specs: Requires SAE 5W-30 specification (Volvo Workshop Manual 2003). Modern semi-synthetics meeting ACEA A3/B3 or A3/B4 are acceptable.
Emissions: Formal Euro 3 certification applies to all models for applicable markets (EU Regulation (EC) No 715/2007).
Power Ratings: Measured under SAE net horsepower standards (post-1972). Figures represent engine output with accessories (Volvo Technical Data Sheet 2001).

The Volvo B 4204 T17 was used across Volvo's S40 and V40 platforms with transverse mounting. This engine received no significant platform-specific adaptations between sedan and wagon variants, though turbocharger and intercooler piping layouts were identical. All applications are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front of the engine block, near the timing belt cover (Volvo Workshop Manual 2003). The code will read "B4204T17". Visual identification: Cast-iron block, black plastic camshaft cover, and prominent Mitsubishi TD04 turbocharger with top-mounted intercooler visible in the engine bay. Critical differentiation from the B4164T4: The B4204T17 has a 2.0L displacement (83.0mm bore) versus the B4164T4's 1.6L (81.0mm bore). The presence of the TD04 turbocharger differentiates it from naturally aspirated B4204 variants.
The B 4204 T17's primary reliability risk is turbocharger oil return line gasket failure, with elevated incidence in high-mileage or heat-soaked engines. Volvo service data indicates this was a frequent cause of oil leaks and turbo damage, while owner club surveys highlight ignition coil and timing belt issues as secondary concerns. Infrequent maintenance and neglect make regular inspection and adherence to OEM service intervals critical.
