Volvo Engine Codes Database

A Volvo engine code (e.g., B4204T23, D4204T14) identifies the engine family, fuel type, displacement, and variant. Prefix 'B' denotes petrol (Benzin), 'D' denotes diesel. Numbers indicate displacement and configuration: 4204 = 2.0L inline-4. Suffix letters/numbers denote revision and market variant. Source: Volvo VIDA Vehicle Identification Guide.

Volvo has ceased development of new diesel engines. The D4 and D5 Drive-E engines remain in production for certain markets but are being phased out. Volvo plans to sell only fully electric vehicles by 2030. Source: Volvo Cars Sustainability Report 2023.

The B4204T Drive-E petrol engines (post-2018 revisions) are widely regarded as Volvo's most reliable modern engines. Older naturally aspirated inline-5 engines (B5254T) are also durable if maintained. Avoid early VEA engines (2014–2016) due to timing chain tensioner and oil consumption issues.

All modern Volvo Drive-E VEA engines (B4xx, D4xx) use timing chains. Older engines: inline-5 petrol (B52xx) use timing belts (replacement interval: 240,000 km or 10 years). Diesel engines pre-2014 (D52xx) also use belts. Always verify your specific engine code.

Technically possible within the same platform (SPA or CMA), but complex. Requires ECU remapping, wiring harness changes, emissions system modifications, and DVLA notification. Not recommended without expert tuning. Ensure compliance with UK MoT emissions rules.

On the D4204T Drive-E engine, the code is stamped on a label attached to the front timing cover or on the engine block near the oil filter housing. Also check the V5C logbook under 'Engine Number' and the data sticker in the boot or driver's door jamb.

On the UK V5C registration document, look for the 'Engine Number' field (not VIN). This matches the engine code (e.g., D4204T14). If the engine was replaced, this may not reflect the current unit. Always verify physically on the engine block.

The D4204T Drive-E diesel is mechanically robust but prone to EGR cooler failures (TSB 39512) and DPF clogging in urban use. Post-2018 units address early issues. With proper maintenance and AdBlue use, D4 engines can exceed 250,000 miles. Source: Volvo VIDA Service Bulletin 39512.

T5: 2.0L turbocharged petrol (B4204T23), ~250 HP. T6: 2.0L turbocharged AND supercharged petrol (B4204T27), ~310 HP. Both are Drive-E VEA engines. T6 offers higher power but increased complexity and potential for supercharger clutch wear.

Yes. The engine code (e.g., B4204T23) is required for ordering correct parts (ECU, turbo, injectors). Using VIN alone can lead to errors due to platform sharing across Volvo, Polestar, and Lynk & Co. Always verify with the physical engine code on the block.

Yes. High-performance engines (T6, T8 Twin Engine) or engines with known issues (early VEA) can increase premiums. Insurers use engine type to assess risk. Always declare correct engine code to avoid policy invalidation.

The Drive-E VEA engines (B4xx, D4xx) are designed for 200,000+ miles with proper maintenance. Known for aluminium block, direct injection, and compact design. Carbon buildup on intake valves (petrol) and EGR issues (diesel) are common service items. Use Volvo VCC RBS0-2AE specification oil.

Yes. All Drive-E VEA engines (B4xx, D4xx) are interference engines. If the timing chain fails, internal damage is likely. Immediate towing required. Adhere strictly to service intervals: timing chain is 'lifetime' but inspect tensioner at 150,000 km per Volvo VIDA.

Early Drive-E VEA engines (2014–2016): B4164T, B4204T, D4164T, D4204T. Issue: timing chain tensioner wear leading to rattling noise. Volvo issued TSB 39284 recommending inspection/replacement. Post-2018 units feature revised tensioner design.

Yes, but must be declared to DVLA. Changing engine code (e.g., petrol to diesel) may affect MoT emissions testing, insurance classification, and road tax. Source: DVLA Vehicle Registration Guidelines.

Yes. The XC60 T8, XC90 T8, and S60 T8 Twin Engine use the B4204T Drive-E petrol engine paired with an electric motor and high-voltage battery. The engine is calibrated for hybrid efficiency with Atkinson-cycle operation in certain modes.

The D3 (D3204T) 2.0L diesel is generally reliable but prone to DPF and EGR issues in short-trip urban driving. Common in V40, V60, XC40. Service interval: 30,000 km or 2 years in UK conditions. Use low-ash oil (Volvo VCC RBS0-2AE) to protect DPF.

Positions 4–6 of the VIN indicate engine type for Volvo vehicles. Example: YV1A... → 'A' prefix denotes Drive-E family. Use a Volvo-specific VIN decoder via Volvo VIDA or official dealer portal for accuracy. Source: Volvo VIDA VIN Structure Guide.

Some are. Naturally aspirated inline-5 engines (B5254T, B5244T) are simpler and easier to repair than modern turbocharged Drive-E units. However, Drive-E engines offer better efficiency, emissions compliance under Euro 6, and refined performance. Choice depends on use case: restoration vs daily driving.
