Fuel: Petrol
Ref: ECUT100195

Note: This ECU may also fit other models.

The best-documented of the four Bosch MP7.0 units in our table comes with a car, an engine size and a Peugeot or Citroën number. The least documented comes with its Bosch number and nothing more. The closer your unit is to the second, the more the label alone has to carry.

0261204407: the MP7.0 with the most to check it against

0261204407 is the MP7.0 we can check from the most directions. It is recorded against the Peugeot 406 with the 3.0 V6 engine, and our table pairs it with the Peugeot or Citroën number 96 278 902. On the label it is printed with a trailing 80, as 96 278 902 80; both forms refer to the same unit.

With a 406 3.0 in front of you, the car, the engine size and the second number give three separate checks on the Bosch number. That makes it the easiest row on this page to confirm, as long as each number is read from the unit itself.

Why a Peugeot 406 3.0 still leaves two MP7.0 units

0261204076 is recorded against the Peugeot 406 3.0 as well. Among these four rows, that is the only car and engine size on record, and it sits on both 0261204076 and 0261204407. For a 406 3.0 owner, the car and engine confirm the MP7.0 family but cannot choose between the two.

The label does that. Our table lists 0261204076 by its Bosch number only, so where 0261204407 offers a second number to compare, this unit rests on its ten Bosch digits. If your label shows 96 278 902 80, that points to 0261204407. Any other Peugeot or Citroën number on a 406 3.0 unit is still worth sending alongside the Bosch number.

0261204413 and 0261204434: MP7.0 units the label must identify

Half the table offers no Peugeot or Citroën car to check against. 0261204413 has no car or engine size on record with us, so the vehicle it came from cannot confirm it. It does carry a Peugeot or Citroën number, 96 255 523 80, and that is the second way to confirm it: when both numbers on your label match our row, the identification is settled.

0261204434 has no Peugeot or Citroën car on record with us, and our table holds no second number for it. The Bosch number on the label is the whole identification, so those ten digits are the one thing to get exactly right.

No two of the four numbers in this table differ by a single digit, so a copying slip will not land on another MP7.0 row here. It can still land on another unit altogether, because a Bosch number one digit away from any of these can belong to something else. Other Bosch MP7-series units, such as the MP7.2 and MP7.3, are separate units with their own numbers, so check the full name on the label too.

What to copy from a Bosch MP7.0 label

Copy every number on the label straight from the unit: the Bosch number beginning 0261, all ten digits of it, and any Peugeot or Citroën number beginning 96. Then add the car, its engine size and what it is doing wrong. Where a digit is worn or unclear, mark which one instead of guessing: on two of these four units, the label is the only evidence we have.

If the label names a different Bosch unit, look through our Peugeot engine ECU pages, unit by unit or the Citroën engine ECUs alongside them. For an engine ECU from another manufacturer’s car, start at the complete engine ECU repairs page.

Your MP7.0 on our workshop bench

Start with the Repair Form, each number as it appears, then post the unit to us. Ours is a mail-in service covering the whole UK, and the car itself never needs to visit us.

On arrival we log the unit, inspect it and test it electrically, then run diagnostics aimed at the fault you described. Our own engineers trace the failed component and repair it at board level in our UK workshop, under a microscope with temperature-controlled rework equipment. The unit that comes back is the MP7.0 you posted.

We tell you what we have found before any chargeable work begins, and nothing goes ahead without your authorisation. Final testing is the last step before the unit is packed for return, and the repair is covered by our 24-month warranty.

The table below sets out the four Bosch MP7.0 numbers, together with the two Peugeot or Citroën numbers it holds.
