Hello I play with the idea to buy an Alfa159 2.4 JTDM 20V sportwagon from BJ. 2007. Have already read something in the topic AGR and Swirlklappen problems. Think, however, that the simplest solution, regardless of the condition, install a new suction bridge, deactivate the AGR and the Swirlklappen, ready. Does not cost the world. Question: do all diesel engines have a DPF? Or is the DPF special accessory? Is the DPF only installed from a certain year of construction? Did the DPF expand and program if available? Note: (if everything is independent of the registration, since it becomes an export vehicle ) Then another question about the automatic transmission. Is this stable or should you rather use the manual transmission? Which weak point does the 159er have even where you should pay attention to it? Greetings and thanks already
