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 w…

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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
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.
The most common questions about engine codes, what they mean, how to find them and how this database works
The B 4164 S2 can be reliable long-term if its two critical maintenance items are strictly followed: oil changes every 10,000 km with correct synthetic oil to prevent sludge, and timing belt replacement every 80,000-100,000 km. Neglecting either can lead to catastrophic engine failure. With proper care, these engines can easily reach 250,000 km.
The most common and serious issues are oil sludge leading to camshaft wear (TSB-02-01) and timing belt failure due to missed replacement intervals. Other common problems include coolant leaks from aging plastic components and oil leaks from seals. These are well-documented in Volvo's service literature.
The B 4164 S2 was fitted exclusively to the first-generation Volvo S40 sedan and V40 wagon from 1998 to 2004. It was the standard 1.6L petrol engine for these models, positioned below the 1.8L and 2.0L variants in the lineup.
Yes, within limits. Common upgrades include a performance exhaust, intake, and ECU remap. Significant power gains are difficult due to the engine's modest displacement and high compression ratio, but drivability can be improved. Any tuning should be done cautiously to avoid overstressing the internals or exacerbating oil consumption.
Fuel economy is good for its era. Expect figures around 8-10 L/100km (28-35 mpg UK) in mixed driving for a well-maintained car. Economy is heavily influenced by driving style, tire pressure, and the condition of the engine and transmission.
Yes. The Volvo B 4164 S2 is an interference engine. If the timing belt breaks or jumps, the pistons will contact the valves, causing severe internal damage that often requires a complete engine rebuild or replacement.
The engine requires SAE 5W-30 full synthetic oil meeting Volvo specification. This is non-negotiable for preventing sludge buildup in the cylinder head. Using mineral oil or extending change intervals beyond 10,000 km significantly increases the risk of camshaft failure.
