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 m…
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CDZ is a fundamentally simple and robust engine known for its longevity when properly maintained. Its main vulnerability is the timing belt; failure to replace it at 80,000 km or 5 years can cause expensive damage to the camshaft and auxiliary drives. With this service adhered to, and regular oil changes, it can easily reach 200,000 km or more.
The most critical issue is timing belt failure due to neglect. Other frequent problems include coolant leaks from the water pump or thermostat housing, ignition system faults (coil or HT leads), and a dirty throttle body or idle control valve causing erratic idle. These are well-documented in Peugeot service bulletins.
This 1.1L petrol engine was used in the Peugeot 106 (Series 2, 1992-1996) and the Peugeot Saxo (Series 1, 1996-2000). It was typically found in base and mid-range X and XT/SX trim levels, offering a balance of low cost and adequate performance for city driving.
Yes, but gains are modest due to its small displacement and SOHC design. Common upgrades include a performance exhaust and cold air intake, which might yield 5-10% more power. More significant tuning is limited by the engine's architecture. Its strength is reliability, not performance potential.
Excellent for its era. Official combined figures are around 6.0 L/100km (47 mpg UK) for a 106, but real-world consumption is typically 6.5-7.5 L/100km (38-43 mpg UK) depending on driving style and condition. It is a very economical engine, ideal for urban commuting and short trips.
No, it is not an interference engine. This is a key advantage. If the timing belt fails, the pistons will not hit the valves, preventing catastrophic internal damage. However, the camshaft will stop turning, which can still damage the belt-driven water pump, alternator, or the camshaft itself, leading to a costly repair.
Peugeot originally specified a 10W-40 mineral or semi-synthetic oil meeting the B71 2290 specification. A good quality 10W-40 or 15W-40 oil from a reputable brand is perfectly suitable. Regular oil changes (every 10,000 km or annually) are essential for long-term health, especially to protect the timing belt tensioner.
