Chrysler Bosch EDC16U31 Engine ECU Repairs

Type: Bosch Engine Management
Fits: Chrysler
Fuel: Diesel
Ref: ECUT344300

Note: This ECU may also fit other models.

Two numbers on a Bosch EDC16U31 label settle whether this is the right page for it, and only one of them needs to match ours to the last character. The Bosch number, 0281012129, has to agree in full. The Chrysler number printed beside it has been recorded with more than one pair of letters on the end.

Start with the Bosch number, digit for digit

There is only one row in our table for this unit, so matching it is a yes-or-no question rather than a choice between rows. A Bosch number that differs anywhere from 0281012129 is not a near match to this page; it belongs to a different unit. Read it straight off the label, not from memory or paperwork, and check every digit.

The Chrysler number and its suffix letters

Our table prints the Chrysler number as P05033 299AE. Published listings for the same Bosch number also show P05033 299AF and P05033 299AG, and in each case every character ahead of the last two letters is identical. A label ending AF or AG is no reason to think you have the wrong page.

What the change of letters records is not something we read from a label, and we do not guess at it. Send the whole Chrysler number exactly as printed, suffix and all, and it is checked against the unit itself when it reaches the workshop.

A Dodge Caliber unit on a Chrysler page

The spec lines above read Fits: Chrysler, yet the one vehicle our records tie this unit to is a Dodge: the Caliber 2.0 CRD, a diesel, in line with the Fuel entry. The P05033 number on its label is a Chrysler-group part number, and that is why we list a Caliber unit under Chrysler. A Caliber 2.0 CRD owner holding a unit marked 0281012129 is in the right place.

The note under the spec block says this ECU may also fit other models. We name only the Caliber 2.0 CRD because it is the only vehicle on record for this part number. If your unit came out of something else, tell us which vehicle when you send it, and we will confirm from the unit rather than assume.

What we do with the unit once it arrives

Each EDC16U31 that arrives is logged, inspected by eye and tested electrically before any fault-specific diagnosis starts. Board-level work is carried out under a microscope with temperature-controlled rework equipment, by our own engineers in our own UK workshop. We repair the particular fault on the unit you send rather than exchanging it, and the job is not finished until that unit passes final testing.

You hear from us with the findings before anything chargeable is done, and no work goes ahead without your authorisation. The repair is covered by a 24-month warranty.

Sending a Bosch EDC16U31 to us

Units reach us by post from anywhere in the UK. Start with our Repair Form, entering both label numbers exactly as they appear, then the vehicle and what it has been doing.
