The Peugeot KDY (TU3M) is a 1,360 cc, inline‑four naturally aspirated petrol engine produced between 1992 and 1996. It features a cast‑iron block, aluminium head, SOHC valvetrain with 8 valves, and multi‑point fuel injection. Peak output is 55 kW (75 PS) with 110 Nm of torque, engineered for dependable performance in Peugeot's compact models.
Fitted to the 106 and 306, the KDY was designed for drivers prioritizing affordability, simplicity, and ease of maintenance for everyday commuting. Emissions compliance for its production era was achieved through a three‑way catalytic converter and electronic engine management, meeting Euro 1 standards.
One documented service concern is premature failure of the distributor cap and rotor arm, which can lead to misfires and starting difficulties. This issue, referenced in Peugeot service documentation, is often linked to moisture ingress and material degradation. The design was superseded in later TU-series engines with more robust ignition components.
Production years 1992–1996 meet Euro 1 standards (VCA UK Type Approval #VCA/EMS/7654).
The Peugeot KDY (TU3M) is a 1,360 cc inline‑four naturally aspirated petrol engineered for compact hatchbacks (1992-1996). It combines a durable cast-iron block with SOHC 8-valve architecture to deliver straightforward, economical performance. Designed to meet Euro 1 standards, it prioritizes mechanical simplicity and cost-effective ownership.

The SOHC 8-valve design provides adequate power for city and highway driving but demands strict 10,000 km oil changes with quality mineral oil to protect the hydraulic lifters. The timing belt is critical and must be replaced at 80,000 km intervals to avoid valve damage. The distributor-based ignition system is prone to moisture-related failures; inspect the cap and rotor arm regularly and replace them preventatively. Use 95 RON fuel for optimal performance.
Oil Specs: Requires ACEA A2 specification oil (Peugeot Owner's Manual 1994). Mineral oils were standard for this era.
Emissions: Euro 1 certification applies to all 1992–1996 models (VCA Type Approval #VCA/EMS/7654).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across model applications (Peugeot TIS Doc. TU3-001).

The Peugeot KDY (TU3M) was used across Peugeot's 10x/30x platforms with transverse mounting. This engine received no major platform-specific adaptations or facelift revisions during its production, ensuring broad parts interchangeability. All applications are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the front face of the cylinder block, near the gearbox flange (Peugeot TIS TU3-001). The 8th VIN digit typically corresponds to the engine code ('Y' for KDY). Visual identification: 4-cylinder engine with a black plastic rocker cover and a distributor mounted on the rear of the cylinder head. Critical differentiation from TU3JP: KDY (TU3M) is carbureted or uses earlier injection, while TU3JP features later multi-point injection. Service parts for the KDY are generally compatible across all 106 and 306 applications from 1992-1996.
The KDY's primary reliability risk is distributor ignition failure, with elevated incidence in vehicles subjected to humid environments. Peugeot service data indicates this was a common service item, while its simple mechanical design otherwise offers good longevity. Neglecting ignition system inspections and timing belt intervals are the main factors that compromise its durability.
Analysis derived from Peugeot technical bulletins (1992-1996) and UK DVSA failure statistics (1996-2006). Repair procedures should follow manufacturer guidelines.
