How many gaskets do I need to get to change the turbo actuator in an ALH? (doesn't hold vacuum)
Just the manifold and downpipe, or is there a few more that I should get?
I may need to clean up the turbo inside as well after I take the assembly off, never messed with a turbo before.

Re: VNT turbo actuator changeout
I suppose when a VNT-15 is on a TDI
it's hard to get to without removing the manifolds.
Probably can't just come at it from underneath.
I'm not much help with this one yet.
Though I do own a TDI project,
I'm just starting to figure these out.
I have pulled several of these vacuum motors apart before.
On the rabbit VNT-15 projects I switch from vacuum to boost actuated.

Re: VNT turbo actuator changeout
I'll be pulling the whole manifold, there is an exhaust leak going on too. I have to keep the a/c blower on recirculate or smells of exhaust inside a bit.

Re: VNT turbo actuator changeout
well after removing the actuator, the turbo vanes weren't sticking at all - so I decided to keep it simple and not take more apart than needed.
finally got the new actuator
Vacuum still wasn't making it to the new actuator - turned out the vacuum check valve was stopped up with crud?
cleaned it out and it didn't work anymore as a check valve but allowed vacuum and turbo works now. Got one coming from oreally's (uro version $9) - those things are WAY overpriced.
I do need to hook up a temporary boost gauge since I don't have vagcom. I'll worry about the exhaust leak later, I didn't see any visual evidence while under there..

Glad you got it working.
Sounds like a simple fix.
