Although Euro 6 is not mandatory until registrations from 1/1/2015, Vauxhall/Opel have introduced a new Euro 6 engine into the Zafira Tourer and the Meriva. This power plant uses the Ad Blue system where a separate tank filled with a chemical is used to inject fluid into the exhaust. I am not sure yet if this still has a DPF but it should solve the DPF regen issue.Either that or bring its own load of troubles!It may well be that owners of Euro 6 diesels will say "Come back DPF, you worked well!
The Euro spec regs. require every Euro 6 emissions system to last for 160,000 km. I wonder if this means that the exhaust system will be covered by a lifetime warranty?
