Technical My car's engine failure light burned!

The car has gone into limp mode to proetct the engine from damage. You need to get a diagnostic code readout for the car (EODB code reader, Multiecuscan etc). this will tell you where the problem is. Without this or more information on other problems you may have noticed, or recent changes to the car, any diagnosis would just be guessing.

Sorry it's not more helpful.

You are right.
Ecu is gone in recovery mode: ok.
And you have to connect a diagnosis to the ecu to know which is the problem.
But in 9 years and 380.000km the only times that happened something like that were when I had problems of clogged dpf or egr blocked.
In other two occasions I had the failure light on (for example with a pressure sensor pipe broken) but the engine didn't go in recovery mode...the car gone well as usual...
Obviously there are other faults that can cause the recovery mode...maybe a broken flow meter or a other sensor....as you say, you have to use an electronic diagnosis and nothing else.....but he asked what in our opinion can be....and for my experience dpf and egr are two serious candidates
