Description
Control Unit MAGNETI MARELLI IAW 6LP2.01. Fits 1.4 16V KFU engines for CITROËN and PEUGEOT vehicles. Removed from a PEUGEOT 307.
Product Overview
This Magneti Marelli IAW 6LP2.01 engine control unit (ECU) is a direct-fit injection control module for 1.4 16V KFU petrol engines used in Citroën and Peugeot models, notably found in the Peugeot 307. Supplied used, this unit manages fuel injection timing, ignition control, sensor inputs (MAP/MAF, lambda, coolant temperature), and communicates with the vehicle’s immobilizer and dashboard systems. Commonly searched by its part numbers, this ECU is intended for professional garages and experienced DIY mechanics who can perform correct installation and coding.
Why Choose This Unit
Buying a compatible IAW 6LP2.01 replacement can restore reliable engine management, improve drivability, and eliminate error codes related to a failing ECU. The listing includes multiple reference numbers frequently used in searches to help you quickly identify the correct unit for repair or swap.

Installation And Coding – Important
– The unit is used and is “paired” with the original vehicle (VIN/PIN/keys).
– Options to put into service:
1) Cloning data from the old unit (EEPROM/Flash) – after cloning the unit is plug and play.
2) Virginization (reset to blank) and subsequent initialization/telecoding via DiagBox (or online) + key adaptation.
– Recommended to be performed by a professional with PSA service equipment (DiagBox/Lexia/PP2000).
– Before removal/installation always disconnect the battery and follow the manufacturer’s procedure to avoid damaging the unit.
How The Unit Is Replaced
Replacement requires basic electrical and mechanical skills: disconnect the battery, remove the ECU cover (usually located in the engine bay or under the dash depending on model), unplug wiring connectors, unbolt the unit and swap it with the replacement. After physical installation, the unit will typically require either cloning of EEPROM/Flash data from the original ECU or professional coding/initialization to match immobilizer and key data. Follow anti-static precautions and torque specifications where applicable.
Common Failure Causes
ECUs like the IAW 6LP2.01 most often fail due to moisture ingress and corrosion on connector pins, thermal stress causing solder joint fractures, voltage spikes from a weak/incorrectly connected battery, or internal memory corruption. Symptoms include engine misfires, stalling, no-start conditions, intermittent faults, and stored engine management error codes.
Installation Recommendations
- Perform installation in a dry, clean environment and handle the unit by its housing to avoid ESD damage.
- Always disconnect the negative battery terminal before disconnecting the ECU.
- Inspect and, if needed, clean wiring harness connectors; replace damaged pins to ensure reliable contact.
- If cloning is performed, verify successful EEPROM/Flash copy and check that all immobilizer-related functions operate correctly.
- If virginizing and coding, use authorized PSA diagnostic tools and follow step-by-step procedures to program immobilizer and key data.
Notes For Mechanics And DIY Enthusiasts
Search this part by the reference numbers listed above to find compatible units quickly. Ensure you have the appropriate diagnostic and coding tools or access to a specialist workshop for final commissioning. Correct handling and proper reprogramming are essential for reliable operation.
