Turbo actuator

[mtroxel]

IHI turbo was new 50,000 miles ago. Getting P0299's. Found a boost leak, bad clamp. That helped, but still getting the code. Output test on N75 runs normally. Took the DV apart, cleaned it up a bit but all seems well. Now I did this test, grabbed the actuator with a damn-it grabber, and the sound you hear is play in the actuator rod.

Should I just face the facts?

Wastegate bushing has worn out on the turbo. Look up my quick fix on the P0299 thread to buy you some time.

Yea that's my gut. If the slop was just in the actuator arm to the wastegate I think it would sound tinny. This sounds like a bigger piece of steel. I already saw planekiller1's thread a couple days ago. He has skills I don't have.

I'll look yours up.

My feeling is if I remove the 50,000 mile turbo to work on it, I'm putting a new gasket kit on of close to $90. Then I might have fixed my P0299 until the core goes bad. And if my waste gate is shot, then the rest core might not be that far behind. So unless I want to R&R this and put $90 worth of gaskets on it again, wouldn't I be smart just to get one of those IHI's at ECS?

Check rockauto too if you have no interest in upgrading to a K04.

[mtroxel]

This CAEB has 132,000 miles on it. Given this motor's well-documented history of committing suicide, I'm not putting $3,000 worth of K04 lipstick on this pig.

Checked RockAuto. Not that good right now for OE replacement turbos.

[Stazi]

You can also rebuild the wastegate for $50 with a wastegate kit, if you can weld. I did it on my old K03 and then sold it off.

Mine has 121k on it and I smeared lipstick all over it like a $2 whore. lol

I'm not a welder. Saw the one you had for sale, I was about to PM you and see if you still had it. I think I'm headed for that $850 IHI at ECS.

I'm a weak man. I wish I could say that I've never done that. I'm mean....I've thrown good money after bad. Can't say I've ever done a $2 whore.

That's how much an 09 is worth though.

I don't know if it is good money after bad (maybe), i look at it as more of an entertainment budget. Seriously jonesing for a TTRS lately but told myself i would wait 4 more years till the twins start driving and let them drive the avant.

[mtroxel]

... told myself i would wait 4 more years till the twins start driving and let them drive the avant.

When my son was old enough to drive my dad gave me great advice. He looked me in the eye and said, "Kids wreck cars."

What he meant was, buy a piece of for your kids. Plan on them wrecking it, because that's what kids do.

Have a 23 and 22 year old also. My father told me if i want a car go buy one and pay for insurance when i wanted to drive. I have learned my lesson, my wife told me go buy them cars and pay for their insurance. So rather then buying cars for the twins they get my old car that i know the history of and i will get what i want. Quite honestly a 2011 avant will be worth what in 4 years (actual value not enthusiast value) getting off cheaper this way. Daughter just finished law school hoping she will hold on to the cc till the twins start driving so they can have that also otherwise she will trade it in. Put the cars in the kids names when they turned 18 so if there is an accident they cant come after me.


Edit: also when we were young you could find a decent car for 3-5 k not so much anymore.

Fair point.

[mtroxel]

Fellow Ziner A6sport lives across town from me. He had an IHI 06H 145 702 S laying around after he put a K04 in his A5. Only had 22K miles on it so we made a deal. Waste gate and turbine are both solid, so when I get my gasket kit I should be good.

Manual says to "Coat the turbocharger stud bolts with hot bolt past." Never heard of that. Does that act as a loc-tite? Is it necessary?

[Stazi]

Not loctite. You want high temp copper anti seize.

It doesnt have to be copper but it does have to be high temp. I use the purple permatex which is ceramic based good up to 3500* degrees.

[Theiceman]

I think nickle based is for hot bolts. That's what I use. It isn't. Cheap though.

You jinxed me just got back from picking up my daughter after someone ran her off the road into a curb at 45 mph

[Spawne32]

god damn, she ok?

[bb-tt]

Yes thanks. Was too low with both tires flat to see if anymore damage, the tow truck driver said oh look at how the wheel is leaning the control arm is bent but with the wheel pointed straight and once the bent part of the rim was on top didnt look like it was leaning to me. Who knows will definitely need alignment if not control arm. Will hit the junkyards to try and find some rims.

[bb-tt]

Well the good news is that nothing other than the rims /alignment were damaged.
the better news is Zink hooked me up with a set of peelers for 300 bucks. omg it looks like a completely different car ( she is lucky it is the wrong centerbore or i might have kept them for myself)

[mtroxel]

That looks very nice. Doesn't look so Volks-Wagon-y (its a word) now.

So what happened? Some guy changed lanes and she happened to be there?

[bb-tt]

Someone swerved into her lane she drove into the median which had a huge curb.

[mtroxel]

Good for her keeping her head on. You can always buy new wheels....

yes all in all could have been much much worse.

If i read it correctly, your new replacement IHI turbo only last for 50K miles which less than OE one 80K (you are now 132K), right?

my oe IHI was bad at 60k, I would like to think the refurb ones will last a little longer. I went with the BW k04 for the replacement as i figured if i was changing it i might as well upgrade and i know the bw doesn't have the same issue.

Yea you read it right. Believe me, I noticed that too. 50K is not a lot of miles for a turbo. But another way to look at it is that the first owner got 82K out of the first turbo, and my "driving style" (right foot through the floor ) only got 50K out of the second turbo.

[bb-tt]

So are you going to try to fix the wg? Another option cheap Ali Express turbo or eBay.

[mtroxel]

So are you going to try to fix the wg?

No, go back to post #14. I bought a used 22K mile turbo here on the Zine. Just waiting for a gasket kit from ECS. A 50K mile turbo is not young by any means. I didn't want to put more time/money into it.

sucks getting old, i now remember reading that.

Did u put the apr stage 1? Or the first owner?

[mtroxel]

Yep, I did the APR Stage 1....right about the same time I swapped turbos. You don't think there's a connection there do you??

I dont have much mechanic knowledge. But it seem unreasonable for your replaced new OE turbo to failed that fast. My one failed at 100K, I read a lot (also thanks for "SMAC770" information) when i decide which one to buy, the BW rod seem more solid than OE one but it really need to see the real item to compare. I personal think Stage 1 may increase load and cause the rod/seal fail faster.

I just replaced with Audi OE one and hope it can last for another 100K.

The tune does not cause the failure, it just makes it apparent. When on stock and only requesting 12-14 psi the turbo can still make that even with the wg disc leaking when you put a tune in requesting, more than 20 psi and your turbo that should be able to make 25-30 is only making 17 with 98% n75 duty it is blatantly obvious you have issues. Flash back stock to 14 psi and it is not as noticeable until it becomes really bad.

This is the sad reality. Tons of cars running around with leaking WGs, that should be warrantied, but often it is not known until the tune and TD1.....ask me how I know.

My recommendation, if you are under 7/70k and NOT tuned....run a dinan/neuspeed or other piggyback...you will get an underboost, take it to the dealer for replacement.

Now you can get tuned.

Seem the wg is a common reliable issue on audi turbo, but will higher the PSI on the tune put more force on the wg disc and leaking faster?

The higher psi of a tune doesn't push on the wastegate. The charge air is on the other side of the turbo. I think the only real connection is that a tune makes the driver want to use wide open throttle more, which puts more heat into the turbo. Other than that, I have a hard time connecting the higher boost to the waste gate issues.

No it is only an issue on the IHI turbo. I dont know if it is just piss poor design, manufacturing or a little of both. Also no the increased boost should have no effect on how fast the bushing wears out.
