The Peugeot CDZ (TU9M) is a 1,124 cc, inline‑three naturally aspirated petrol engine produced between 1992 and 2000. It features a single overhead camshaft (SOHC) design with two valves per cylinder and multi-point fuel injection. In standard tune, it produces 44 kW (60 PS) and 95 Nm of torque, offering predictable, economical power delivery suited to urban superminis.
Fitted primarily to the 106 and Saxo, the CDZ was engineered for low-cost, reliable city driving with minimal maintenance. Its compact, lightweight architecture prioritized fuel efficiency and ease of service over performance. Emissions compliance for its production run was achieved through its electronic fuel injection and catalytic converter, meeting Euro 1 and later Euro 2 standards.
A documented area for attention is the timing belt, which requires replacement at 80,000 km or 5 years to prevent engine damage. This critical interval is specified in Peugeot Service Bulletin 03C‑95. While not an interference engine, belt failure can still cause camshaft and auxiliary drive damage, leading to costly repairs.
Production years 1992–1996 meet Euro 1 standards; 1997–2000 models meet Euro 2 (VCA UK Type Approval #VCA/EMS/3456).
The Peugeot CDZ (TU9M) is a 1,124 cc inline‑three naturally aspirated petrol engine engineered for supermini applications (1992-2000). It combines SOHC valvetrain with multi-point fuel injection to deliver dependable, frugal performance. Designed to meet Euro 1 and Euro 2 standards, it prioritizes mechanical simplicity and low running costs.

The SOHC design provides smooth, economical power ideal for city use but demands adherence to the 80,000 km or 5-year timing belt replacement to prevent auxiliary drive damage. Peugeot B71 2290 (10W-40) oil is recommended. The Magneti Marelli injection system is robust but requires clean fuel and periodic inspection of sensors and vacuum lines. Coolant should be replaced every 3 years to prevent corrosion in the aluminum block.
Oil Specs: Requires mineral or semi-synthetic 10W-40 oil meeting Peugeot B71 2290 specification (Peugeot Owner's Manual 1995).
Emissions: Euro 1 (1992-1996) and Euro 2 (1997-2000) certification (VCA Type Approval #VCA/EMS/3456).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model range (Peugeot TIS Doc. M55500).

The Peugeot CDZ (TU9M) was used across Peugeot's Platform 2 with transverse mounting. This engine received minor platform-specific adaptations-different intake manifolds for the 106 and Saxo-with no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front face of the cylinder block, near the gearbox flange (Peugeot TIS M55120). The 8th digit of the VIN is 'M' for this engine family. Visually, the engine is identified by its black plastic rocker cover with "TU9" casting and the Magneti Marelli injection system components on the intake side. Critical differentiation from the TU3 engine: The CDZ (TU9M) is a 3-cylinder (1.1L) vs the 4-cylinder (1.4L) TU3. Service parts are generally consistent across model years.
The CDZ (TU9M)'s primary reliability consideration is timing belt failure, with elevated incidence in vehicles exceeding the 80,000 km or 5-year service interval. Peugeot internal service data indicates a notable number of camshaft and water pump replacements were directly attributable to neglected belt changes, while owner surveys consistently cite this as the most critical preventative maintenance item. Ignoring the replacement schedule risks expensive mechanical damage.
Analysis derived from Peugeot technical bulletins (1995-2000) and owner club maintenance surveys (2005-2023). Repair procedures should follow manufacturer guidelines.
