I wouldn't ignore these errors. Seems to be a mixture problem at partial load.
That may result in burnt valves, when it's not repaired.

Check for any air leaks in the inlet system.

THANKS ALOT kinketotua , for now the errors is gone , i drive some more km and let you know , but is a good
start , thanks oldford too for interest to my problem , the car is abut 2 years that run in this way , if had to
broken so will broken probably for another reason , the problem probably is multilply and is a choice of the
howner , he dont want the light on ! this is the reason , thanks anyway to interest to my case ,

And how much did you charge the owner for this software update?
And have you warned him about the risk of damaging the engine?

Yes i warned the howner but i repeat it is his choice, for the price ,this is the final of all work in progress of the car i have to
make some calculation but i think i will put it in the amount of the repair and at the end is all, im ignorant in this case i
don't know how to charge , but the car before me was in another 2 garage and the response was the same .........
i think is like all the repair some think is strange some think is matter of money !
