As the title states I have this really odd rattle occur whenever I let off the gas. I pin pointed it to my actuator/waste gate.

The actuator arm seemed to be working so I took my down pipe off and removed the backing plate. The waste gate seemed to be very loose and had quite a lot of play. I uploaded a video to show you.


What can I do to fix this issue?

 

Bump. Anyone know what I need to do? Rebuild? New turbo?

 

You need to get a good use exhaust housing and with that I don't think you have or will have strong boost because it is not holding pressure

 

im sure boost is fine. i actually think i have this rattle too. just noticed it today. its play between the rod and the "sheeth" but remember that the exhaust gas puts pressure on the flapper door to shut it.

if it bothers you, someone that rebuilds turbos can probably fix it, or you can get a new housing. or let it go. hate to say it.

 

The hinge bushing is worn out. You'll have to separate the shaft to replace the bushing.

I just bought a decent used housing and swapped everything over.

 

BNR can replace it for you:

PS in case you didn't know... you have an 89-91 (S5) turbo

 

Mine has same problem. It definitely needs fixed...u will have uncontrollable boost, wastegate will get stuck open closed etc...

 

Where did you purchase your used housing?

 

I just purchased a used/junk turbo off the classified section here.

 

Is BNR a reputable source?

 

Yes, quite a lot of the people on this forum have BNR rebuilt/modified turbos:
