Peugeot Engine Codes Database

A Peugeot engine code (e.g., EB2, EP6, DV6, DW10) identifies the engine family, fuel type, displacement, and variant. EB2 = 1.2L PureTech 3-cylinder petrol, EP6 = 1.6L Prince/THP petrol, DV6 = 1.6L HDi diesel, DW10 = 2.0L HDi diesel. The code determines specifications, compatible parts, and emissions standards.

Yes, but production is declining. Peugeot continues to produce BlueHDi diesel engines (DV5 1.5L, DW10 2.0L) for models like the 3008, 5008, and commercial vehicles. However, PSA/Stellantis plans to phase out diesel by 2030 in line with EU emissions targets and electrification strategy. Source: PSA Sustainability Report 2023

The DW10 2.0L HDi diesel is widely regarded as Peugeot's most reliable modern engine, often exceeding 200,000 miles with proper maintenance. The XUD9 (1.9L diesel, 1985-2000) is legendary for durability. Among petrol engines, the EP6 THP (post-2015 revised version) is more reliable than early variants. Avoid early 1.2L PureTech (2012-2022) due to wet belt issues.

Most modern Peugeot engines use timing belts, not chains. The 1.2L PureTech (EB2) uses a 'wet belt' running in oil (2012-2022), which has proven problematic. The 1.6L THP (EP6) uses a timing chain. HDi diesel engines (DV6, DW10, DW12) use traditional timing belts requiring replacement every 125,000 miles or 5 years. Source: Peugeot Maintenance Schedule 2024

Early 1.2L PureTech engines (EB2, 2012-2022) have experienced significant reliability issues due to wet timing belt degradation. The belt disintegrates in oil, blocking the oil pickup and causing engine failure. Peugeot issued a recall in 2021. The Gen3 PureTech (2023+) replaces the wet belt with a timing chain, addressing this issue. Source: Peugeot Service Bulletin EB2-2021-01

On the Peugeot 308, the engine code is typically located on the timing belt/chain cover or camshaft cover. For PureTech (EB2) engines, check the front timing cover. For THP (EP6) engines, look on the camshaft cover label. For HDi diesels (DV6/DW10), the code is stamped on the engine block near the oil dipstick or on a white label. Also check the V5C logbook under 'Engine Number'.

On the UK V5C registration document, look for the 'Engine Number' field (Section 7, not VIN). This matches the engine code (e.g., EB2DT, DV6DTED). If the engine was replaced, this may not reflect the current unit. Always verify physically on the engine block. The V5C also shows cylinder capacity in cc (Section P.2).

Common HDi diesel issues include: DPF clogging in urban driving (requires regeneration), EGR cooler failures (especially on DV6 1.6L), AdBlue system faults on BlueHDi models (pump/injector failures), and timing belt wear (critical adherence to 125,000-mile/5-year intervals). The DW10 2.0L is generally more reliable than the DV6 1.6L. Source: Peugeot Service Information

HDi (High-pressure Direct Injection) is Peugeot's standard diesel technology with common rail injection and turbocharging. BlueHDi adds selective catalytic reduction (SCR) with AdBlue injection for Euro 6 emissions compliance, significantly reducing NOx emissions. BlueHDi was introduced in 2013 and is required for Euro 6 compliance. Both use DV and DW engine families.

Yes. The engine code (e.g., EB2DT, EP6FDT, DV6DTED) is essential for ordering correct parts (ECU, turbo, injectors, timing components). Using VIN alone can lead to errors, especially on models with multiple engine options. Always verify the physical engine code on the block or label before ordering parts.

Yes. High-performance engines (1.6L THP 200+ HP) or engines with known issues (1.2L PureTech wet belt) can increase premiums. Insurers use engine type, power output, and reliability data to assess risk. Always declare the correct engine code to your insurer. Source: UK Insurance Industry Guidelines

The DW10 2.0L HDi engine is designed for 200,000+ miles with proper maintenance. Known for robust construction and reliability. Key service items: timing belt replacement every 125,000 miles/5 years, oil changes every 12,500 miles, DPF regeneration monitoring. Many examples exceed 250,000 miles with documented service history.

Yes. All modern Peugeot engines (PureTech EB2, THP EP6, HDi DV/DW) are interference engines. If the timing belt/chain fails, the pistons will contact the valves, causing catastrophic internal damage. Immediate towing required if timing component failure is suspected. Adherence to service intervals is critical.

The 1.2L PureTech (EB2, 2012-2022) has experienced widespread wet belt degradation issues. The belt disintegrates in oil, blocking the oil pickup. Peugeot issued a recall in 2021. HDi diesel engines (DV6, DW10, DW12) use traditional belts requiring strict adherence to 125,000-mile/5-year replacement intervals. The 1.6L THP (EP6) uses a timing chain.

Yes, but must be declared to DVLA. Changing engine code (e.g., petrol to diesel, or different displacement) requires DVLA notification, may affect MoT emissions testing, insurance coverage, and V5C registration details. Ensure the replacement engine meets Euro emissions standards for your vehicle's registration date. Source: DVLA Guidelines

Peugeot PHEV models (3008/5008 Hybrid, 508 PHEV) use the 1.6L THP (EP6FDT) petrol engine combined with electric motors, not PureTech. The system produces 225-360 HP combined output with 35-37 mile electric range. PureTech EB2 is used in mild-hybrid applications in some markets.

Peugeot specifies 0W-30 or 0W-20 synthetic oil meeting PSA B71 2312 standard for PureTech EB2 engines. Oil capacity: ~3.5L (1.2L EB2). Critical: Use only approved oil to prevent wet belt degradation. Change interval: 12,500 miles or annually. Source: Peugeot Owner's Manual 2024

Positions 6, 7, and 8 of the VIN indicate engine type for Peugeot vehicles. Example: VF3LCYHZH... where 'YHZ' indicates a 1.2L PureTech EB2 engine. Use a Peugeot-specific VIN decoder for accurate interpretation. The VIN is located on the windscreen, door jamb, or V5C. Source: Peugeot VIN Decoding Guide

The XUD9 (1.9L, 1985-2000) is legendary for simplicity and durability, often exceeding 300,000 miles. Modern HDi engines (DV6, DW10) are more efficient and powerful but add complexity (DPF, EGR, AdBlue). For pure reliability, XUD is superior. For efficiency and emissions, HDi/BlueHDi is better. Trade-off between simplicity and modern standards.
