I have a opel zafira egr electronic problems, then you need to replace.

The problem is that it cost around 350 euro and the machine is not ce is it worth.

I think I have figured out that the gallo54 is able to work on this ecu, but the problem is that it only allows you to write, then should I find a ori to modify, and then write.

The fact is that I do not know the rooster is in fact working on this type of intervention, or perhaps the risk of messing up everything??

Someone has got to test??
