Citroen / Peugeot Bosch MP7.3 Engine ECU Repairs

Type: Bosch Engine Management
Fits: Citroen / Peugeot
Fuel: Petrol
Ref: ECUT102195

Note: This ECU may also fit other models.

Only one detail can rule a Bosch MP7.3 out of this page: a Bosch number other than 0261206565. The car, the engine and the label’s second number can each add confidence, but none of them can disqualify a unit whose ten Bosch digits match ours.

Our table holds that single unit, so the question for your ECU is whether it is this one, not which row it belongs to.

Why the Bosch number alone can rule an MP7.3 out

The Bosch number begins 0261 and runs to ten digits. If any one of them differs from 0261206565, the unit is not the one this page covers, however closely the car fits. If all ten match, you have the right page, whatever else the label or the car suggests.

Copy the digits from the label itself. A Bosch number one digit away from this one can belong to an unrelated unit, so one wrongly copied digit points the enquiry at the wrong ECU. If a digit is scuffed or faint, tell us which one instead of filling it in.

The MP7.3 name helps, though less than the number. Some listings group the MP7.2 and MP7.3 together, but they are separate units with their own numbers, so go by the full name and the Bosch number on the label.

The Peugeot 306 1.8 16V on record for this MP7.3

What we have on record for 0261206565 is the Peugeot 306 with the 1.8 16-valve petrol engine. If your unit came from a 306 1.8 16V, the model, the capacity and the valve count all agree with our record, and that adds real weight to a matching Bosch number.

A different car does not rule the unit out. The spec lines name both makes, yet we have no Citroën car on record against this number, and the note beneath them says this ECU may also fit other models. For a unit from a Citroën, or from a Peugeot other than the 306 1.8 16V, the Bosch number has to decide it alone.

96 356 738 80: the second number on an MP7.3 label

An MP7.3 label also carries a Peugeot or Citroën part number beginning 96. The one printed with this unit is 96 356 738 80.

Our table lists the unit by its Bosch number only, so the 96 number serves as a cross-check rather than a stand-in for the Bosch number. If yours reads 96 356 738 80 and the Bosch digits match too, the identification is firm. If it reads differently, send it all the same: our technical team confirms coverage for a specific unit rather than guessing.

What to send with a Bosch MP7.3

Complete the Repair Form, with each detail filled in: every number on the label as printed, the car with its engine size and valve count, and a short description of the symptoms. Then post the ECU to us on its own; ours is a mail-in service across the whole of the UK.

Should the number point to another Bosch unit, Peugeot engine ECUs by family name and the Citroën engine ECU catalogue are where to go from here. For a car from another manufacturer, begin with engine ECU repairs for any other vehicle.

Repairing your MP7.3 at component level

Our own engineers repair every unit in-house, in our UK workshop and on our own equipment. Each MP7.3 is logged, inspected and tested electrically, then taken through diagnostics aimed at the fault your form describes.

Our findings reach you before any chargeable work, and the unit waits until you authorise the repair. The fault is traced to component level and repaired under a microscope with temperature-controlled rework equipment. Passing final testing is what marks the repair as finished, and that repair carries our 24-month warranty.

The single Bosch MP7.3 number we repair is set out in the table below.
