The engine code is essential for ordering parts, diagnosing issues, and verifying compatibility. It is not the same as the VIN or chassis number. This guide shows exactly where to find it - by model and engine type - using official Citroën and DVLA sources
A unique identifier stamped on the engine block or cover used for parts and service.
The vehicle identification number that holds encoded vehicle and engine information.
The chassis or frame number used for registration and legal identification.
Locate the engine code on the timing cover, near the oil filter housing. It is stamped into the metal or on a white label adjacent to the turbocharger.
The engine code is located on a white label attached to the oil filter housing or near the EGR valve. It reads 'EB2ADTD' for the 1.5L BlueHDi diesel variant.
Open the bonnet and look at the front right of the engine. The code is on a white label near the timing belt cover. Confirm 'EB2FAT' for PureTech petrol; diesel models show 'DV5FCD'.
The engine code is cast into the front of the cylinder head, near the thermostat housing. Look for 'TU5JP4' or 'TU3JP' depending on displacement.

Citroën's PureTech family uses variable valve timing and direct injection for improved efficiency and reduced emissions. Introduced in 2014, it powers the EB2 (1.2L) and EB3 (1.0L) engines across the C3, C4, and Berlingo range.
Dual continuous variable valve timing (VVT) on intake and exhaust camshafts optimises valve overlap for improved combustion efficiency. Combined with high-pressure direct injection (200 bar) and turbocharging for downsized performance.
EB2 (2014)
Basic VVT, 1.2L 3-cylinder
EB2ADT (2017)
Enhanced VVT, improved turbo response
EB2FAT (2020)
Mild hybrid integration, Atkinson cycle
Timing belt degradation
Early EB2 belts susceptible to oil contamination; replace at 10 years/180,000 km
Carbon buildup on intake valves
Direct injection design; requires walnut blasting service
Oil consumption
Some early units experienced higher than expected oil use

Track BMW engineering across decades
Transition to modern overhead cam engines and introduction of diesel technology for efficiency.
1.4–1.6L inline-4 SOHC petrol. Modern overhead cam design. Balanced performance and economy. Foundation for 1980s Citroën range.
1.9L inline-4 indirect injection diesel. Citroën's first mass-production diesel. Reliable, economical. Established diesel credibility for the brand.

Authoritative data on Citroën's global engine production, plant operations, and strategic partnerships. All figures sourced from Stellantis Annual Reports, Sustainability Reports, and EU industrial compliance records.
Citroën manufactures engines at three primary Stellantis facilities, each specialising in specific families.
Citroën produces approximately 300,000+ engines per year across Stellantis plants. Note the steady decline in Diesel production due to Euro 6d and WLTP regulations, while Hybrid and EV integration rises.
Note: Diesel production has declined steadily due to Euro 6d and WLTP regulations (Regulation (EC) No 715/2007). Hybrid and plug-in hybrid integration rising.
Strategic collaboration via TPCA joint venture (2005–2021). Shared 1.0L EB1/1KR-FE engine powers the Citroën C1, Peugeot 107/108, and Toyota Aygo across Europe.

Shift in production reflects EU emissions policy and changing consumer demand across UK and European markets.
This aligns with Commission Regulation (EU) 2017/1151 (WLTP/RDE) and EU 2035 ICE phase-out roadmap.

The most common questions about engine codes, what they mean, how to find them and how this database works
A Citroën engine code (e.g., DV6TED4, EB2ADTD) identifies the engine family, fuel type, displacement, and generation. Prefix: Family (DV/DW = diesel, TU/XU = petrol, EB/EP = modern petrol). Numbers: Displacement (6 = ~1.6L). Suffix: Variant (TED4 = turbo diesel, Euro 4). Source: Citroën Service Box Doc. A15001
Yes, but production is declining. The DV5 (1.5L BlueHDi) and DV6 (1.6L BlueHDi) diesel engines are still used in the C3, C4, and Berlingo (2024 UK models). However, Stellantis plans to phase out diesel by 2030 in line with EU emissions targets. Source: Regulation (EC) No 715/2007
The EB2 (1.2L PureTech) is generally reliable with proper maintenance, though early versions had timing belt issues. Older naturally aspirated engines like the TU5JP4 and XU10 are also durable if maintained. Avoid early DV6 HDi engines due to turbo and EGR issues.
Most modern Citroën PureTech petrol engines use timing belts (not chains), requiring replacement every 10 years or 180,000 km. BlueHDi diesel engines also use belts. Older TU/XU engines used belts with 100,000 km intervals. Always check your specific engine code.
Technically possible but complex. Requires ECU remapping, wiring harness changes, and mount modifications. Not recommended without expert tuning. Ensure compliance with UK emissions rules and DVLA notification requirements. Source: DVLA Vehicle Approval
On the DV6 or EB2 engine, the code is stamped on the timing cover or on a white label near the oil filter housing. Also check the V5C logbook under 'Engine Number' for the legal identifier.
On the UK V5C registration document, look for the 'Engine Number' field (not VIN). This matches the engine code (e.g., DV6TED4). If the engine was replaced, this may not reflect the current unit.
The DV6 HDi diesel engine (2004–2015) is known for turbo actuator failures, EGR clogging, and DPF issues in urban driving. Citroën issued Service Bulletins recommending EGR cleaning at 120,000 km. High-risk for UK high-mileage urban drivers.
DV5: 1.5L diesel (DV5FCD) – used in C3, C4, Berlingo. DV6: 1.6L diesel (DV6TED4) – used in C4 Picasso, C5. Both are BlueHDi common rail engines, but DV5 is newer with improved emissions compliance. DV6 early models had turbo issues.
Yes. The engine code (e.g., EB2ADTD) is required for ordering correct parts (ECU, turbo, injectors). Using VIN alone can lead to errors due to platform sharing. Always verify with the physical engine code.
Yes. High-performance engines (EP6FDT in GT models) or high-failure engines (early DV6) can increase premiums. Insurers use engine type to assess risk. Always declare correct engine code to your provider.
The EB2 PureTech (2014–present) is designed for 180,000+ km with proper maintenance. Known for lightweight aluminium construction. Timing belt is a critical service item (~10 years/180,000 km) – failure causes catastrophic damage.
Yes. All EB/EP PureTech engines are interference engines. If the timing belt fails, valve-to-piston contact is likely causing severe internal damage. Immediate towing required – do not attempt to restart.
EP6DT (1.6L THP): High failure rate in early models (2007–2010). EB2 (1.2L PureTech): Improved but still a wear item. Citroën extended warranty on EP6 via Technical Bulletin SB-12-07-01.
Yes, but must be declared to DVLA. Changing engine code (e.g., petrol to diesel) may affect MoT, insurance, and emissions compliance. Keep documentation of the replacement for verification. Source: DVLA guidelines
Yes. The C5 Aircross Hybrid and DS 7 Crossback E-Tense use the EB2FAT PureTech petrol engine paired with an electric motor. The engine is de-tuned for hybrid efficiency with Atkinson cycle operation.
The EB2ADTD (1.2L PureTech diesel) is generally reliable but prone to EGR and DPF issues in urban driving. Common in C3 BlueHDi. Service interval: 12,500 miles or 12 months in UK conditions.
Positions 4–7 of the VIN indicate engine type for Citroën vehicles. Example: VF7XXXXXX → positions 4-7 reference engine family. Use Citroën Service Box or a brand-specific decoder for accurate results. Source: Citroën Service Box Doc. A15001
Some are. TU5 and XU engines are simpler and more durable than early DV/EP series. However, modern PureTech and BlueHDi offer better efficiency and emissions compliance under Euro 6.
