Does this ECU fit your car?
MJD 6F3.D6 ECUs were fitted to Fiat cars with the 1.3 Multijet engine. The model and year alone are not enough. Look at the label of your ECU: if it shows number 51862582 and type MJD 6F3.D6, it is the same version. A different part number is a different ECU.
Tests, options and warranty
- Every ECU is tested on the bench and fitted to our test car before dispatch.
- Paid extra options: EGR OFF and DPF OFF.
- Warranty: 6 months.
Fitting without programming
Virgin Plug & Play means that once connected, the ECU adapts itself to the car and immobiliser. Two things are needed: the same part number (51862582) and a working immobiliser.
The IMMO OFF version is available on request, but it leaves a red immobiliser warning on the dashboard and a fault in diagnostics that cannot be removed without pairing with the immobiliser. Virgin has no such fault.

Common questions about ECU 51862582 MJD6F3.D6

What is the difference between IMMO OFF and Virgin?
With IMMO OFF the car runs, but a red immobiliser warning stays on the dashboard and a fault remains in diagnostics that cannot be cleared. The Virgin version does not have this fault, which is why we recommend it.

Do you offer EGR OFF and DPF OFF for this ECU?
Yes, these are paid extra options that we carry out on request before the ECU is shipped.

What is the warranty on ECU 51862582?
The warranty is 6 months. Before dispatch, the ECU passes a bench test and a test in our test car.
