If you are troubleshooting injection or starting problems and looking for an exact part by number, this unit is what you need. It is a used original part from Citroën/Peugeot (PSA) cars, suitable for professional repair and home service.

Part Key Numbers (for lookup and verification)
– Bosch: 0261207318 (M7.4.4, ME7.4.4)
– PSA/Siemens: 9653492680, 9643897580
– OEM PSA: 1940T1, 1940T2
Tip: Always compare all numbers on your unit’s nameplate with those listed. Matching the base number (0261207318) and PSA codes significantly increases the certainty of compatibility.

Compatibility
– Citroën Xsara Picasso 1.6 8V NFV (TU5JP), petrol
– The unit can also be found in other selected PSA models with the same engine/installation; however, the above part numbers and type of connectors are decisive.
– Exchanges between 1940T1/1940T2 tend to be possible depending on the SW version – we recommend checking in advance with diagnostics or comparing labels.

Technical information
– Manufacturer/type: Bosch M7.4.4 (ME7.4.4), petrol, multi-point injection
– Power supply: 12 V, controls ignition and injection
– Connectors: 3 multi-pin PSA (typical for Bosch ME7.4.4)
– Location in the car: engine compartment (ECU box according to specific equipment)
– Immobilizer: part of ECU – requires pairing with BSI/keys or data cloning

Assembly and coding – important
– It is a used ECU. Before starting the car, it is necessary:
– pair the unit with BSI and immobilizer (telecoding),
– or clone data (EEPROM/FLASH) from the old drive to this one,
– possibly use the “virgin” procedure (if your service offers this service).
– We recommend entrusting assembly and coding to an experienced PSA diagnostician (Lexia/PP2000/DiagBox).
– After assembly, erase errors and perform basic adaptations according to diagnostics.

When do you typically change this ECU
– Engine won’t start despite spark/fuel, repeatedly falling into emergency mode
– Errors of ignition circuits, injectors, sensors (e.g. P0351–P0354, etc.)
– Damage to the ECU due to moisture, short circuit or unprofessional intervention

What to check before buying
– Matching Bosch number and PSA codes with the old unit
– Motor type (NFV/TU5JP) and connector design
– The condition of the wiring/earthing in the car – you will prevent the fault from recurring

Content and status
– We supply the Bosch M7.4.4 engine control unit itself
– Used original part; visual condition according to the photo. Accessories (mounts, screws, BSI, keys) not included unless otherwise noted.

Why choose an original used part?
– 100% compliance with PSA installation, reliability and correct maps
– Quick and economical repair compared to a new ECU
– Easier coding and telecoding compared to universal replacement

Assembly and coding – how to proceed
– Data re-cloning: the surest way – transfer the EEPROM/Flash content from the old ECU to this one (you will keep the immo code and configuration). Recommended, no further pairing required.
– Virginization: putting it in a “new” state and then coding with diagnostics (Lexia/DiagBox) to your BSI and keys.
– Changing the “set” (ECU+BSI+keys): alternative if you have a complete set. This offer only includes the ECU itself.
Recommended installation in a professional service. Before installation, check the power supply, grounding and harness to avoid immediate damage to the new unit.

Typical symptoms of a fault in the original ECU
– Cold/warm starts, cylinder misfiring, idle fluctuations
– Throttle, mixture (lambda) errors, ECU communication failures
