Peugeot 307 HDI -06 - Anti Pollution faulty- flappering sound air intake - Pansarharry

Hello.

My car shows "Anti pollution faulty" and makes a flappering sound from air intake. Sounds like a broken exhaust but it cames from air intake box. It starts but dont run clean.

It is like air sometimes flows in wrong direction from the turbo.

What can cause this problem??

You might have a split in one of the air intake pipes, either between the turbo & intercooler or intercooler & inlet manifold.

Sometimes difficult to find, look for a telltale spray of black oil from any split.
