Turbos blown?

[nobodeuno]

13 S6 and was driving on the highway this afternoon and knew something was wrong. No power and no boost. Pulled off the highway and to a stoplight and the car just shutdown and wouldn’t start back up. No CE lights or anything. Finally got it started so I could pull it out of the busy intersection and got it towed to a local shop. Based on what I am readings sounds like turbos are gone. I heard a rattling noise...

Sucks because I was about to trade the same car in lol

Anyways what is a reasonable cost for replacement labor. Looks like parts are around $5-6k? Is 10hrs sufficient. I am pretty handy and could probably do it myself but really don’t have the time. What am I looking st for a fair price at a local Indy shop. Just want to make sure I know what what is reasonable when I call tomorrow.

Thanks for the help in advance!

Not sure but if it is blown turbos please report this to the ntsb. Be sure to report that you sudddenly lost power on the highway without warning. Audi may be forced to cover your expenses in the future.

Not sure on the s6, but when I had my Gti it was common for the wastegate valve to tear and your boost wouldn’t get held in, hopefully you have more of an issue like that???

this sounds identicle to the confirmed blown turbo failure stories.

without even looking at the car, id say 99% yes.


dealer and full replacement, your looking at $10-12k.

independent shop with OEM parts, close to $8k.

if you choose to replace only the CHRA (the bearing and impellers only) your closer to $4k. little over $2k in parts, $2k labor.

Exact same thing happened to me. Sorry! I replaced the turbos and all other potential parts at an Audi dealer and it was $9997.

So you can just rebuild the turbos. I will probably opt for this given I am just going to trade the car in. Trying to get out for as little as little possible. Can they simply send the turbos odd to rebuild or is this something that most shops can do?

Not sure what their labor rate is but if it is around 10hrs at $100 an hour then seems like labor wouldn’t be much more than $1k?

If there is not a lot of damage to the exhaust housings/compressor housings then you could just replace the CHRA’s. If you are planning on trading it in, you might just want to buy the CHRAs +/- new compressor housings from china (alibaba) and throw them in. Honestly anything you throw in there is probably gonna blow again soon since you are not replacing the oil screen. So drive it straight to the dealership for trade lol

This is why I would not buy a used one. But I don't blame the owner either.

Not sure I want to do this if it will be blow again and since the car will be apart seems like it won’t be much more to replace the screen. I was mainly just trying to save as much money as I can while repairing.

[CpkS7]

If you are past warranty and replacing turbos, is there any not to go with the rs6/7 turbos vs the stock?

[johnsonfit]

OP - Just out of curiosity, what were your oil change intervals?

[nobodeuno]

Cost I think would be the main reason. I think you have to upgrade a lot of other parts along with it don’t you? Tuning...downpipes?

Has anyone had experience purchasing and replacing CHRA‘s. Found a couple online but not sure what ones would be the best. Also I found some S8 Turbos on eBay for $800. Are these a direct fit?

So is it the screen in the oil separator that should be replaced?

Thanks

You can use the RS7 CHRAs with stock tune and stock downpies. Go read the 4.0TT Blown Turbo Poll (https://www.audizine.com/forum/showthread.php/808057-4-0TT-Blown-Turbo-Poll?p=13046852&viewfull=1#post13046852) thread

OP sounds like he wants to sell, but crutched by bad turbos. It may sound stupid, but sage 3 sounds comparable to a dealer turbo replacement dollar for dollar. Oh and you have fuck tons of power instead of blown turbos.

He wants to sell it, not fall in love with it all over again [:D]

[Marc R]

I got a complete RS6 kit for sale, 1 : 1 swap on the S6

Uhh Yes very TRUE!!

Question, I was talking to a shop about replacing just the CHRA's and they are saying that there would be a $450 increase in labor...is that true?

I reached out to Silly Rabbit and waiting to hear back also found these on ebay...would they work?

Replacing just the CHRAs actually is FAR LESS labor than replacing the turbos in entirety, because it can be done without taking off the entire front end (which is a must in order to get to the turbo housing bolts). If you are also replacing the turbo oil screen, then yes, you also need to take off the whole front end, to include the charge air cooler housing along with the oil separator. Once you are there, it would take slightly longer to swap out the CHRAs than it would to simply replace the turbos entirely, but not much. If you are doing JUST the CHRAs (and not the turbo oil screen), then it should only be a few hours worth of labor.

[nobodeuno]

I found a set of used OEM turbos for $1500 came off a low mileage S6. Would you all go this route and change the screen or take a risk with changing just the CHRA’s and not the screen. Either way I am trading in but just concerned the turbos will blow before I make it to the dealer. Although I guess I have a bit of a risk with the used turbos also...

Also not sure where to buy CHRA’s from anyways since silly rabbit hasn’t gotten back to me and anything from Allin’s a is going to take forever to get here. Thoughts.

I went with Silly Rabbit CHRAs in the sock S6 size. I would highly recommend replacing the turbo oil screen and checkvalve even if you are just trading it in. With the screen partially obstructed you may not make it very far before it pops again. I did all the work myself and had about $2500 in parts. I did wait quite a while for my CHRAs from SillyRabbit...

Thanks and good to know. I don't know that I can wait very long...so that is why I was leaning towards going with the used set of turbos however I'm nervous about that because I'm not sure I'll know if they are actually good until they get installed. Visually they seem fine and been told they are within tolerance levels for shaft but wish there was a way to know for sure. At least with the CHRA's I'll know they are good...

I definitely plan on replacing the screen and check valve even though I'm trading it in...don't want to turn over a car that is a ticking time bomb. Just want to try and spend the minimum.

Also does the ACC and Top View camera need to be recalibrated after bumper removal? If so can this be done via VAG?

[bays6]

I went with a used set when my turbos went. It was the driver's side that blew! Anyway, I agreed with the seller that I would pay the remaining half of the balance once my shop inspected the turbos. Everything was done through PayPal which had protection in case the turbos were bad. Total cost for me was about $4800 installed with all the upgraded parts that went along with it. I had the the plastic shafts replaced with the metal ones, the new screens (plus a drilled hole in them), actuators, etc. Basically, since they had it opened up, my mechanic suggested I do all those upgrades that audi had done over the years of improving the quality of those parts.

[flyfishing]

i was told it is never a good idea just to replace one turbo in a car and you should do two.

Going with turbos from a low mileage S6 sounds like a good idea. You can easily change out the turbo oil screen at the same time for less than an hour's worth of labor on top of the turbo work. If you weren't trading it in, I'd say change out the PCV valve as long as you're in there, but now that Audi is covering that repair for 10 years, I think you can not do this and trade the car in with a clean conscience. Also, no need to recalibrate anything after bumper removal. Just don't turn on the car while any of those sensors are unplugged and you'll be completely fine. I've removed the front bumper on these cars at least a dozen times and they've always been completely fine. You don't even need to put the car on a lift or jackstands to do this work. Just have the wheels turned all the way in either direction in order to get to the bolts holding the bumper to the fenders. Once you've done this you can disconnect the battery and you're good to go.

Yes, it looks like they will as they are the RS7 turbos as well. Looks like they offer a 6 month warranty as well but not sure how that works from China. The new part number is shown here to confirm the match.

My understanding was that the S8/RS7 turbos won't exactly match up if replacing just the CHRA's...you have to purchase the entire unit. At least that is what I read in another thread.

Quick question for anyone that might know. How do you inspect a turbo before installing to ensure that it is still good? If the fins are good and shaft play is minimal am I good or are there other things that may not present until after the install?

Thanks in advance

Too bad your on the other side of country
