Hi guys, Any input on this would really help? So Viano 3.0 V6 2007. it sounds like its sucking / blowing air when under load and goes into limp mode, Read the code P0406 (EGR) So i cleaned the EGR & Re-installed- Same Code. So i replaced the EGR - Same Code. Still getting the same problems. Limp mode and sounds like sucking or blowing a lot of air when under load. "will not make the air noise when stationary" Next Global Diagnostic: No other faults found (Just the ERG) So they individually tested all sensors (Mass air flow and the like) No faults found. I have also cleaned the DPF, and im not getting much crap our from that. Still the same code comes up after it goes in to limp mode. I have checked the Air intake, well i have removed the air box and "choked" the air intake towards the Turbo and all the rubber pipe are collapsing as they should, so no leak on intake. Today i also got P0299. Something about the Turbo // Supercharger under boost. If anyone can point me in the right direction it would really help. i have it booked in on Thursday at a local place to start striping to discover the issue but it not going to be easy to find and that means ££££££. Thank you for all your help in advance.
