Been noticing a lot of diesel stink coming from the vents. Checked around for the leak and found a good soot trail coming from the little actuator arm in the middle of the turbo. Anyone know if there is a fix for this? Anyone have Rebuild kit?

Don't really wanna drop $1200 on a new turbo. And also don't wanna open mine up without having a backup on hand. Or at least a rebuild kit and some instructions. Thanks!

That is the waste gate.. I'm unaware at to its serviceability But most likely the turbo itself is fine just blowing by the bushings on the pin of the waste gate itself .. Not a diesel guy so I cant say this is fact just a thought. you may be able to get just the exhaust manifold

I've found the "cartridge" which seems to be the middle chunk with the turbines , oil inlet, and the little waste gate arm on it. Problem is I find them for every car except the 2.0 diesel.
I can't seem to find any parts for them turbo. I would suspect the same. Probably just a bushing or gasket needs replaced. Car is driving fine.

Center section shouldnt have the wastegate arm .. its built into the manifold .. the actuator bolts to the compressor housing . can you get a pic of the problem spot on yours ?

I can see the soot .. your sure its not leaking at the manifold gasket down below there.. again im not familiar with diesels and to be honest I have never until now seen a turbo with the wastegate as part of the center cartridge I was kid of hoping a fellow Diesel Cruzer would have piped in by now .

I don't see any soot trails down that low. And it is way too hot to be feeling around with my hands. So I'm assuming this is it based on the soot trails...

This looks very similar (for a 1.9 VW). For the parts I can see. Dorman 667-004 Dorman Turbocharger Cartridges | Summit Racing

No idea lol. If I had a spare turbo I would take this one apart. Unfortunately I have not found any photos or videos of a rebuild so I have no clue what's actually inside... the more I look at the vw one the more confused it makes me lol. Idk if it moves a part which is mounted in the manifold side housing maybe??

Thanks @boraz for the links. I wasn't sure if it was a generic turbo used for all 2.0 Diesels. I did find the larger leak that was causing the odors in the cabin. It was the main output of the turbo. The opening of the clamp was facing downwards where I couldn't see there was actually a soot trail coming from it. I seperated the exhaust and found the metal gasket was bent from being smashed in there. so I straightened that out and put it back together. The car was now throwing codes. for Injection quanity too high, and Turbo performance low. I figured rather than wait on the car to retune itself I'd just flash it with the tuner to reset the fuel tables. She's running better now and no more smell. I probably won't worry about the smaller leak coming from the arm at the moment. I may down the road look into swapping the turbo out, because I still have strange boost numbers. But for now It's just a car to get me to work.

So my egt keep rising and my map readings are going down. I think my turbo is on its way out. I've been looking for a used one. But the part# of what's on my car isn't matching anything. The gm# is correct. But the bottom left Garrett # is wrong

Swapped it with a turbo from a wrecked car I found online. Preliminary results are the egts are lower. However I'm still only hitting 180 kpa imap readings. That's the highest I can get it and it reaches that around 2/3 throttle. If you floor it, It just falls on its face
