The Volvo B 4164 S2 is a 1,587 cc, inline‑four petrol engine produced between 1998 and 2004. It features an aluminium block and head, dual overhead camshafts (DOHC), and Bosch Motronic 4.4 electronic fuel injection. In standard tune for the S40/V40, it delivered approximately 74 kW (100 PS), providing responsive performance for Volvo's compact models.
Fitted primarily to the Volvo S40 and V40 (P1 platform), the B 4164 S2 was engineered for agile, efficient urban driving with a focus on refinement. Emissions compliance was achieved through precise electronic fuel metering and a three-way catalytic converter, meeting Euro 3 standards applicable for its production period.
One documented service consideration is the potential for oil sludge accumulation in the cylinder head, particularly when oil change intervals are extended. This issue, noted in Volvo Technical Service Bulletin TSB‑02‑01, can lead to blocked oil passages and camshaft wear. The engine was part of Volvo's modular "B4" family, sharing core architecture with other 1.6L and 1.8L variants.
Production years 1998–2004 meet Euro 3 emissions standards (Swedish Transport Agency Type Approval Records).
The Volvo B 4164 S2 is a 1,587 cc inline‑four petrol engine engineered for compact hatchbacks and sedans (1998-2004). It combines a lightweight aluminium block with a DOHC valvetrain and Bosch Motronic 4.4 electronic fuel injection to deliver responsive, efficient power. Designed to meet Euro 3 emissions regulations, it balances everyday drivability with modern emissions control.

The DOHC design offers good performance but requires strict adherence to timing belt replacement intervals (every 80,000-100,000 km). The aluminium construction is lightweight but sensitive to overheating. Regular oil changes (every 10,000 km) with full synthetic 5W-30 are critical to prevent sludge buildup in the head, documented in TSB-02-01. The Bosch Motronic system is generally reliable but sensitive to poor electrical grounds. Use of high-quality fuel is recommended.
Oil Specs: Requires SAE 5W-30 synthetic oil (Volvo Workshop Manual 2000). This specification is critical for protecting the DOHC valvetrain.
Emissions: Certified to Euro 3 standards for all production years (Swedish Transport Agency).
Power Ratings: Measured under SAE net horsepower standards (Volvo Technical Specification Sheet B4164S2).

The Volvo B 4164 S2 was used across Volvo's S40/V40 platforms with transverse mounting. This engine was part of the modular B4 family and shared many components with the B4184S/S2 1.8L variants. Minor ECU revisions were implemented during its production run, but no major facelifts created significant interchange limits for core mechanical parts. All adaptations are documented in OEM technical bulletins.
The engine code "B4164S2" is typically stamped on a flat pad on the front face of the engine block, near the timing belt cover. The 8th digit of the VIN is often '4' for 1.6L engines in this platform. Visually, it is identified by its transverse mounting, aluminium construction, and the Bosch Motronic ECU. Differentiation from the 1.8L B4184S is by the engine code stamping and displacement; it is distinct from the later B4164S3 by minor ECU and emissions revisions.
The B 4164 S2's primary long-term concern is oil sludge accumulation in the cylinder head, particularly when oil change intervals are extended beyond 15,000 km. Volvo TSB-02-01 documented this as a cause of blocked oil passages leading to camshaft and follower wear. Consistent operation and strict adherence to maintenance schedules are critical for preventing costly internal damage.
Analysis derived from Volvo technical bulletins (1998-2005) and workshop manuals (2000). Repair procedures should follow manufacturer guidelines.
