Peugeot 129-XZ5 Compatible Models

The Peugeot EB2 was used across PSA's A‑segment platforms with transverse mounting and co‑developed with Toyota for the B‑Zippy II project. This engine received platform-specific adaptations—revised engine mounts in the Peugeot 108 and modified accessory brackets in the Citroën C1—and from 2013 the camshaft metallurgy update, creating minor service part distinctions. Partnerships enabled Toyota Aygo to share the same powertrain. 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.

Common Reliability Issues - PEUGEOT 129-XZ5 Compatible Models

Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

Exhaust camshaft lobe/tappet wear
Symptoms: Ticking noise from cylinder head (especially on cold start), misfire on cylinder 3, reduced power.
Cause: Insufficient surface hardening on early camshafts combined with marginal oil film strength under high load.
Fix: Replace camshaft and tappets with updated PSA-specified parts per service bulletin; verify oil pump pressure and clearances.
Timing belt tensioner failure
Symptoms: Squealing or chirping from front cover, erratic idle, potential belt jump if severe.
Cause: Plastic tensioner pulley degrades over time; early designs prone to bearing seizure under heat cycles.
Fix: Install latest OEM timing belt kit including metal‑core tensioner per PSA procedure; inspect water pump simultaneously.
Throttle body carbon fouling
Symptoms: Rough idle, hesitation on acceleration, stalling, stored P0507/P2101 codes.
Cause: Oil vapour from crankcase ventilation deposits on throttle plate and bore over time.
Fix: Clean throttle body with approved solvent; perform throttle adaptation reset via diagnostics after cleaning.
EGR valve clogging
Symptoms: Rough idle, increased emissions, limp mode, DTCs P0401/P0402.
Cause: Carbon buildup restricts EGR valve motion and flow path due to recirculated exhaust gases.
Fix: Clean or replace EGR valve and cooler per PSA guidance; verify vacuum actuator function and reset adaptations.

PEUGEOT 129-XZ5 FAQ Common Questions Answered

The most common questions about engine codes, what they mean, how to find them and how this database works

The EB2 is generally reliable if maintained properly. Early models (2010–2012) had camshaft wear issues, resolved from 2013 onward. With regular oil changes (every 15,000 km) and timely timing belt replacement (60,000 km), it can exceed 200,000 km without major issues.

Main issues are exhaust cam lobe wear (pre-2013), timing belt tensioner degradation, throttle body carbon buildup, and EGR valve clogging. These are documented in PSA service bulletins and are manageable with preventative maintenance.

The EB2 powered the Peugeot 108 (XZ5) from 2014 to 2021. It was also used in the Citroën C1 (PM2) and Toyota Aygo (AB20) as part of the B-Zippy II joint venture. All three share identical engine architecture and service requirements.

Minimal tuning potential. The EB2 lacks forced induction or variable valve timing. Minor gains (~2–3 kW) are possible via remap or cold air intake, but mechanical limits and emissions constraints make significant tuning impractical and unsupported by PSA.

Excellent for city use. In a Peugeot 108, expect ~5.2 L/100km (city), ~3.8 L/100km (highway), or ~68 mpg UK combined. Real-world mixed driving typically yields 60–70 mpg UK when driven gently and maintained properly.

Yes. The EB2 is an interference engine. If the timing belt fails or jumps, pistons can collide with open valves, causing severe internal damage. Strict adherence to the 60,000 km belt replacement interval is essential.

PSA specifies 5W‑30 synthetic oil meeting PSA 971‑B2 (or ACEA A3/B4). Always use quality oil and change every 15,000 km or annually to protect the camshaft and ensure smooth operation.
