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

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
