Did you get a MGU that matches the region of your car?
You cannot install a European MGU in a US car, for example.
Your problem sounds like a coding issue.

Thanks, yes i did, but it was verginsed and validated with me car. 

any other ideas please?

Of course you can install EU MGU in US CAR.
That's nonsense.

Thanks mate for the confirmation.. any idea what might be the problem?   does the MGU needs to be valdite with the ATM?
