About this file

Description

Stock read from the MJD 6F3.D3 ECU in a Fiat Doblo. On the label you should see 51784561; the software in the read is 3056D346. This one was read with both FLEX and KTAG.

Keep it for recovery after a failed flash or when a unit needs the factory software back. If the immobiliser is the issue, there’s a 51784561 immo off dump for vehicles you own. Units with hardware 51805372 need a different file: the 51805372 3454D366 dump. See also choosing between original, virgin and FRF files.

FIAT DOBLO MJD 6F3.D3 51784561 3056D346 DUMP is an original (stock) ECU file for the Fiat DOBLO fitted with the MJD 6F3.D3 engine control unit. It matches hardware number 51784561 and software number 3056D346. The file was read with FLEX and is supplied exactly as read from the unit, byte for byte.

Typical use: restoring a damaged or corrupted ECU to factory software, recovering after a failed flash, or as a clean base before any modification. Before writing the file, confirm that the hardware and software numbers printed on your ECU label match the numbers above; writing a file to a unit with different numbers can damage the ECU.

After secure checkout the file is available for instant download from your AutoECUFile account, and it stays there for later downloads. Need another version of 3056D346, or a file that is not listed? Send us a file request and we will source it for you.
