Just a heads up to anyone looking for a OEM/genuine ALH TDI actuator on Amazon, I emailed Garrett through their website a while back asking if the "Garrett" seller account was theirs, and they replied that they do not sell their actuators on Amazon (reply below).

No one on here suggests taking the actuator apart and fixing it?
I posted a picture of what it looks like inside, on another post.
They come apart easy and go back together easy.

I have been documenting:
  • What all the parts are in the turbo control system and where you can get them
  • How it works
  • A problem determination process when it doesn't
You may find it helpful if you have an ALH engine, see here


There is, alas, no Shazamm! answer, no magic bullet. You can learn the ins and outs of the system and perhaps fix it yourself inexpensively. Or you can take it to a dealer who may do the equivalent of changing stuff, part by part, until it works again, starting with the most expensive items. People (and mechanics)who really know the TDI inside and out are passing rare, though there are many here. Unfortunately, they cannot give you answers without a lot of information you probably won't be able to provide. This is one of those situations where you have to know a lot before you can frame a question that gives enough information that people here can tell you what's going wrong.
A TDI will last a long, long time, but along the way things will happen. If you commit to the long run, you need to understand how it works (again see my page on the Turbo), so you understand how things work, how they go wrong and how to do enough basic problem det, so you can narrow in on what causing your problem.
I bought my '03 TDI in '05 with 11K on it and have put 250K since then. Lately the turbo system has been dysfunctioning...so now I have to put some time, some sweat, some dues in for all those trouble-free miles.
The more you know, the sooner you fix or head off problems, the cheaper and cleaner will be your recovery and use of your TDI. Good luck

I can't find it so I'll post it here:
Ignore the springs,.. I flipped the can and ran it manually controlled by boost,.. for the old 1.6.
Those aren't stock springs.


That's the insides of the all-metal can.
I open it up by prying the crimp apart.
The washer was all rusty.
Won't rust now,.. it's stainless.
That's 6m1 allthread.

First using a 1/8" flat screwdriver and prying directly away from the can.
Tink, Tink, Tink,.. until it raises a little.
Then I get a bigger screwdriver in there and turn it to pry the crimp open.
Go around it like a can opener.
