Start with the badge on the car. Both Bosch references covered on this page are recorded against the same model, the Volkswagen Corrado G60, so a control unit taken out of a Corrado wearing that badge is worth checking against what follows.

The two references are Bosch 0 261 200 342 and Bosch 0 261 200 346. Which of them you are holding is a question for the label on the case, and the numbers printed there are what we work from when a unit reaches the bench.

What the G60 badge tells you about this unit

Where independent records name a car for either reference, the car they agree on is the Corrado G60. For 0 261 200 346 they add the engine size too, describing the car as a 1.8 G60.

That is a short record, and this page does not stretch it. No other model has the backing of two independent sources in the records we checked, so no other model is named here. If your unit came out of something other than a Corrado, go by the numbers on its case rather than by the car.

Audi, Seat and Skoda appear in the spec lines at the top because this page sits among our VAG part-number pages. The outside record for these two references is narrower: it places them on Volkswagen alone, and no Audi, Seat or Skoda application is recorded by more than one source.

If the Volkswagen you are working on carries a different unit, try Volkswagen engine management beyond the Corrado G60.

Reading 0 261 200 342 and 0 261 200 346 off the case

Records of these units give the Bosch number and a Volkswagen part number together, as they appear on the case label. Take both from the label itself, every letter included, and hold them up against the two pairings below.

For 0 261 200 346, the Volkswagen number is 037 906 022 EG. That is the pairing in our own table, and independent listings print the same two numbers side by side.

For 0 261 200 342, listings print 037 906 022 CN with the Bosch number.

A label showing one of these Bosch numbers beside a different Volkswagen number still deserves a look. Give us exactly what is printed, and our engineers will confirm whether it is a unit we cover before you commit to anything.

If neither Bosch number is on your label, the unit is not one of these two, and the complete engine ECU repair range is the place to find where it belongs.

Listed as MP4.0 here, and as Digifant or DF1 elsewhere

This page calls the unit an MP4.0. Other sellers list the same Bosch references as Digifant, some add DF1, and at least one catalogue prints all three names together.

The name is the seller’s choice. The Bosch number is not, and it reads the same under every name. If a search for Digifant brought you here, compare the number on your case with the two above; if it matches, this is the page for your unit, whatever the listing called it.

Repair on the bench, from arrival to final test

Our service runs by post, so the unit travels to our workshop from wherever in the UK the car happens to be. It is booked in on arrival, given a visual inspection and tested electrically before any diagnosis aimed at the reported fault begins.

The work itself stays in-house, carried out by our own engineers on our own equipment; component work is done under magnification with temperature-controlled rework gear. We look for the individual component that has failed and repair it there, leaving the rest of the unit as it came out of the car.

When diagnosis is complete, we contact you with what we found and the repair it needs, and nothing further is done until you have agreed to it. The unit comes back only after it has passed final testing, and the repair is covered by a 24-month warranty.

To have yours looked at, give our engineers both label readings through the Repair Form, with the model and badge of the car it came from.

The two Bosch references this page covers are set out below.
