Most of the bad reputation surrounding this engine stems from the Euro 5 EGR issues and the injector seal design flaws, both of which have been largely resolved in Euro 6 versions (post-2014). If you are shopping in the used truck market, look for a late-model Renault T with the DF1070. Check the service records for the injector seals, listen for the turbo spool, and you will likely have a very profitable asset for years to come.
