E70 twin-turbo diesel service history

[ForbesZ]

Is there anyone out there that can give us feedback about the service history of the new twin-turbo diesels?

I've been anxiously waiting for the E70 twin-turbo diesel to be available in the US, but as I wait, I see that the turbo diesels from Mercedes and Volkswagen are noted for having a lot of problems.

It also makes me nervous that the US based stealerships don't have mechanics experienced with servicing diesels, so if there are a lot of problems with the new models, it might end up being a case of the blind leading the stupid.

If anyone has any experience with the twin-turbo diesel motors, please post feedback.

Thank you!
