I've got an EGR fault code on my 407 HDi RHR with 160,000 kms, P0401. Something about restricted airflow. Is it possible to clean the EGR without removing it? What do you guys do with your EGR's?
I was told by the local Peugeot dealer that I had a blocked EGR valve. I had the engine decarbonized by the local franchise of Carbon Clean Australia. I think it cost about $165. The motor is now running very well and I don't have an EGR problem.
