Default P0011, P0021 and a blown turbo...

So i was cruisin along in my 04 STi last weekend and all of a sudden those two codes poped up. Being about a mile from my house i continued to drive home. I started hearing scraping noises coming from the turbo until eventually it started sounding like a blender. From what i could see there was no smoke at all.

After doing some research and picking up a used VF39 with no shaft play and 18000 miles, i learned that P0011 and P0021 is related to an oil issue. I saw some threads from a few guys stating that after their turbo replacment there motor died, which deffinatly scared me.

So my questions are what should i be looking for to avoid this? Whats the best way to check for oil clogs to the turbo or the AVCS? And what else could cause an engine failure after those codes and a blown turbo?

Thanks

seems like you may have run it out of oil or didnt change the oil often enough

this is almost always a maintenance issue and from too infrequent oil changes

your engine is almost certainly all done

Thats horrible

I'm usually pretty good with my oil changes but latley i have been really busy, its also really cold in new york. I havnt let my oil level get too low, but im deffinatly overdue for an oil change.

how possible that this is an oil quality issue with the banjo screen being clogged at the turbo? Whats the best thing i can do to try an avoid this? and if it is done what parts would i most likley need to replace?

I'm hoping its just a clogged Filter at the turbo and just not so great oil going into the AVCS.

One other thing, I was getting a whining noise from the rear of the car. Sounded like the feul pump. Would a blown turbo be causing the fuel pump to be working harder?

all of the issues that you are now having......the CEL's and the blown turbo tell of an oil system failure


it could be several things....but when it hits like this all at once...it is usually called a 'catastrophic failure'

do NOT try to drive the car or run the engine until you get this figured out

you MAY be able to save some of the engine...may not

Its been sitting in my driveway ever since the codes first appeared. The motor seemed fine while i was driving it home though, just no power because there was no boost. How would i go about Telling if its a catostrphic failure? What would you do?

I was going to replace the turbo tommorrow...

Replace the turbo, do a complete oil change, remove the screens at the banjo lines for the oil at the turbo, break turbo in and hope for the best IMO. Unless you feel like doing a tear down on the engine to check for and survey any damage, there is really nothing else to do that I know of. And if you tear the engine down point you may as well rebuild it at that point anyways.

well how many people replace a blown turbo that still works great? quite a few. its the posts that people like me put up and it first starts with a blown turbo then an engine.

i can tell you what happened to me and the mistakes i made, make sure your boost controller vacuum hoses are in good order, pushing 19psi on mine with bad hoses ended up with a snapped turbo shaft filling the engine full of metal shavings, then after two engine flushes, two oil changes, engine finally failed.

i would first look for metal shavings on the dipstick, drain the oil too and strain it though a paper mask or something and look for glitter type shavings, mine was copper/goldish color which is babbit which = bearings being shaved down from all the metal going through the oil system.

just because your turbo failed does not mean your engine is toast! just do some good doctoring and inspect everything.

if you find zero shavings on the oil, change it anyway, replace turbo and vacuum lines since you have an 04. clean your i/c just incase some shavings from the turbo went down your i/c and are lodged in the i/c.

i wish they made a high flow filter on the turbo oil return that would catch everything before entering the oil pan.

i have a TON of pics of what the engine looked like on the inside after running it with shavings in the engine, it lasted about 500 miles but it was a gamble i was making that i did not win, it ended up trashing the ENTIRE engine, heads are junk since they are all scared up, cams are scared up, crank and rods and totally junk, oil cooler-chunk it, turbo was is prob junk as well but i have not taken it apart but more than likely shavings went down that too since i already had the filters taken out of the avcs and the turbo, only salvegable item was the block which still had great crosshatching still in the cylinder and the pistons looked pretty good for 90k imho.

let us know what you find, hopefully it is not catastrophic.

The same sequence of events happened to me 8 months ago. I did everything, replaced turbo with a used vf-39 replaced both oil control valves and cleaned all avcs lines. Nothing helped really. I was able to get the codes to go away for 1 month. My big mistake was false hope, after a month of no codes I installed a rotated 30r and now here I am with a topspeed ss1 block. Honestly if I could tell you one thing it would be just save your time and money and get ready for an engine build. Sorry man best of luck I felt your pain.

Yeah im just gonna have to hope for the best. I pulled it in the garage last nite and swapped the turbo. I noticed two things, the T-fitting on the boost controller vacum hose is broken in half and also the steering felt very weird. Like it was easy until the wheel got to a certain point then it would get difficult but just for a second, then continue to feel normal. Ive herd that these two codes could be thrown by the belt skipping teeth.

Also the turbo had a pretty good amount of shaft play and i did not notice any metal shavings at all. I change the oil three times before installing the new turbo. havnt started it yet because im waiting for a new T-fitting from the dealer. Itll be here thursday.

Incubus, I had the same thing happen to me, 06 STI at around 92,00km on the factory turbo and long block. Pulled the p0011 codes and lost boost pressure. I feel for you and if you don't have filings in the oil you are doing better than me, much better. My oil levels were fine when it happened, I was told by the dealer that the supply line was faulty and that the turbo bearings died from starvation then decided to blow apart. (At the dealer because of a useless 3rd party warranty) Life ended for the stock motor and turbo with catastrophic failure. If you are lucky you can get back on the road with just a short block and turbo.
I unfortunately didn't have that luck and am now $20,000 deep into a new motor from Josh at IRR and Sean at Vigilant Motorsports. I am new to tuner cars and this stuff all came unexpected as I was keeping up with the oil changes and maintenance myself. I was noticing a significant amount of burn in the last few months before the turbo kicked the bucket but was told it's "normal" could have saved myself some big money with a preemptive turbo swap.....
At least this build is gonna be huge....
Good luck with your repairs.

Yeah i dont have anykind of warranty.....which is great. And what sucks more is i just got it back from a body shop after spending getting some paint touched up because of some jack***, i was on my way home from the shop...

Having no metal filings does give me some hope, but as subie-love said its probably false hope. I'll start preparing for a build and stop being in denyal, but i deffinatly dont have 20,000 to spend....

I'll let everyone know how it goes, thanks to everyone who responded.

if you have no shavings in the oil then that is a +. my first turbo went but did not dump any shavings, i was fine until the second turbo went, filling the engine full of sparklies, my findings are a few pages down, destroyed the whole engine.

good luck and if you plan on keeping the car, start stock piling parts or sell it once you get it running.

My 05 has been loosing a quart every 1k. Its not a ringland, which was my first guess and also the easiest to check. No codes and no sparkles in the oil either. What should I look for when I pull the turbo this weekend? Oil in the I/C? In the dp? Excessive shaft play?
Advice/suggestions are appreciated.
Car has 50k on it and is stg 2...

That is a lot of oil burn. Thats what I was getting. The dealer told me bad supply to the turbo from none OEM oil lines but that was BS. The builder pulled the turbo apart and told me that the the bearings went and there was shaft play and a lose bolt and the blades all mixed into the destructive failure of my motor. I had minimal sparklies but once it happens you might as well do a build.

I am fairly new to turbo'd cars but everything I've seen says that burning that much oil means that the turbo is the culprit.
Oil in the I/C, check the lines and the banjo filters, I was also told that my Intake manifold was sparkled...maybe check that too?

So heres What i did and what my outcome was....

First i threw in some fresh oil and a new filter, idled it for about 15 min, drained and then replaced the turbo. Also replaced any lines that looked bad.

I then removed the AVCS solenoids and soaked them in WD-40. When i shook them to see if the spring and mechanism inside the solenoid worked properly, a good amount of sludge came out. So i repeated, Shake then soak shake then soak.

Bolted everything back together, changed the oil three more times with new oil filters each time. Primed the turbo and started her up, been about 100 miles and no codes have apeared and she seems to be running better than before.

O i also flushed the coolant, Without the Conditioner (suby dealer told me that you shouldnt use it with the STI ). Thanks again to everyone

Well, I'm kind of nervous now. I originally had the 0011 & 0021 codes back in December but turned out it was due to a dirty oil filter. Once the oil/filter change was done, no more codes and the car ran great.

I was going through about 1qt of oil every 3k miles or so, and knew the turbo was probably going south. Well, last week the clutch went and I had that replaced. As soon as I pick it up from the shop, I hear a very faint rattle once boost starts to come on.

I take it back to the shop the next morning and on the way, throw 0011 & 0021 again. The rattle seems to get a little louder as well. The car ran fine at idle, no smoke, and accelerated normal (without going into boost). The shop calls and tells me the turbo is going out. Now I have a new BNR 18g on order but am now fearful it may be something more.

I don't want to put on a new turbo and then have the motor grenade in a couple of months. I'm going to have to have the shop do a thorough engine check before the turbo install to make sure everything is good first.
