Passat 1.6 TDI Turbo flutter

I noticed that turbo is making flutter sound when revving. I monitored live data and the flutter sounds when the EGR valve opens. If I unplug MAF-sensor, EGR stays closed and flutter is gone.
EDIT: It seems like the noise is coming from the EGR-valve, not turbo. If I plug in EGR restrictor plate, flutter noise isn't so loud anymore. EGR is about 4 months old and works fine.

Delete EGR and DPF = happy turbo

[@yanisluce2257]

it is dangerous for the car ?

[@muhammadabdulalim3033]

mine dose the exact same just had the turbo replaced never done it before i dont know what it could be

[@L4tem4n]

It was EGR valve noise. When you rev the engine, EGR valve opens and closes which causes noise. It is normal

[@energymaster190]

I got the same sound in a passat 2.0 tdi, it was the dpf clogged, i needed to delete it for turbine integrity preservation

[@L4tem4n]

I've driven 50000km after the video without issues. I also got the car remapped. Oil ash volume is 60g so I may have to wash the DPF at some point. In my country you will soon get very big fine if you get caught with deleted DPF or EGR.

@@L4tem4n Yes, it's suggested to clean it up, but in my case was too late for cleaning, and i had no alternative than deleting it, in my country the dpf off can be punished, but its hardly observable if the car will not exhaust that much smoke, so i was able to get away with that :))

hi, did you manage to sort this out with an egr replace or something else? If i unplug maf the flutter disappears for me as well, however that means that the turbo doesnt spool up as high either so cant be 100% sure its just the egr doing dumb stuff...

[@L4tem4n]

Hi! I have done nothing and the car still works fine after 250 000 km. I also got the car remapped and no issues with turbo or EGR.

@@L4tem4n vw concern cars do some wonky stuff these days, but no need to worry then it seems. also, does your car or did it ever jerk a little bit when you let off the throttle too quickly? because im thinking that the flutter and the jerk are somewhat related.

[@L4tem4n]

@@222Berci222 Yeah, that's normal for 1.6 TDI engines. Both my dad's car and mine do that.

It s normal I have the same its the dpf working

[@gedora16]

usualy ppl pay to have sound like that, u got it for free... and wont it to desapear lol

[@elvisrahimic2274]

how did you do this ?

[@L4tem4n]

It's stock. It has been doing that as long as I have owned the car.

[@Alexandru5001]

@@L4tem4n Your DPF is clogged, that's why is making that noise.
