Description
Control Unit MAGNETI MARELLI IAW 6LP2.01. Fits 1.4 16V KFU Engines For CITROËN And PEUGEOT Vehicles. Removed From A PEUGEOT 307.
High-quality engine control unit (ECU) IAW 6LP2.01 from Magneti Marelli, suitable for 1.4 16V KFU petrol engines used in CITROËN and PEUGEOT models such as the Peugeot 307. This unit is ideal for professional workshops and experienced DIY mechanics searching by product codes (e.g. 9657429580, 9647498180, 194031). The ECU manages fuel injection, ignition timing and engine sensors to ensure optimal performance and emissions. Replacing a faulty unit can restore drivability, eliminate limp-home mode and clear engine management faults when combined with proper coding or cloning.
Key Benefits
- Direct fit for vehicles equipped with IAW 6LP2.01 engine management
- Supports full engine management functions: fuel injection, ignition, sensor processing
- Searchable by multiple product codes for fast identification
- Suitable For Mechanics And Skilled DIY Enthusiasts
How It Is Replaced
Replacement should be done methodically: always disconnect the battery before starting. Locate the ECU (position varies by model—commonly in the engine bay or behind the glovebox), disconnect electrical connectors, remove fixing screws and brackets, fit the replacement unit and secure all connectors. After mechanical installation the unit usually requires cloning or telecoding to match vehicle-specific data (see Installation and Coding – Important below). Verify all connectors are clean and pins are undamaged before final assembly. Perform a full system check with appropriate diagnostic equipment and clear any residual fault codes.
Why This Part Fails Most Often
Common causes of ECU failure include water ingress and corrosion, thermal stress from engine bay heat cycles, electrical surges or poor battery/charging system condition, and mechanical damage to connector pins. Symptoms of a failing ECU include no-start or hard-start conditions, frequent stalling, loss of power, irregular idling, and persistent engine management fault lights. Failures are usually related to environmental exposure or electrical faults rather than a scheduled wear item.
