Volkswagen Passat - 1.9TDi noise - Goller Ricsi
I bought a B6 Passat about 2 months ago. One day on my way home from work I put my foot down a bit and it started making this airy/banging/puffing noise. First I thought it’s the exhaust leaking but when I hold the exhaust pipe shut I can’t see smoke coming from anywhere else. Then I thought maybe it’s mechanical and maybe the timing skipped and a piston hit a valve bent, but the timing belt looks to be in very good condition and is tight. I started the motor with the timing belt cover off for which I had to remove the egr valve tube first and when I started the car to see how the timing belt behaves I noticed that it’s the same noise coming from the EGR valve except it’s louder with the tube off. Any suggestions would be appreciated.

Check the turbo hoses for leaks, maybe one has split.
