Exclamation turbo problems

i have a 2002 Audi A6 2.7t with 60,000 miles. My turbos just went out. what is the best option for me to go to fix my problem. Is it easy to replace the turbos myself. and if anyone is selling some turbos for the 2.7t let me know.

How do you know your turbos are out? What are they doing?

They are making a siren/whining sound. plus there is no get up and go from the car. Its like there is no horse power being made for the car to go like it should be.

Hrmm thats odd. I'm new to these cars but my brother has a 93 Twin Turbo Supra and I know a bit about turbos. Maybe your piping or tubing needs to be replaced. I looked on the forums and it seems a lot of people replace it because of issues like this. And another thing, 60,000 miles is not a lot for a set of stock turbos unless you drive like a mad man. I would check for a tubing leak personally.

If you had blown a turbo they would be huge amounts of white smoke coming out of the tail pipe.

Thanks for the reply's guys. I drive my car A to b normal driving style easy on my baby. I treat her good. There was no smoke from the tail pipe. Maybe the turbos are failing. I will check for any kind of vacuum leak or c-claps that have broken off. The car just has no power when you push on the gas. and like i said the there is a whining/siren sound coming from sounds like the turbos.

You might have blown a diverter valve or throttle body boot. It's at least worth checking.

Update!

I started the car and checked under the car to see where the sound is coming from. there is a rattling sound coming from the the passenger side and underneath where the turbo is. So is the rattling sound a turbo failing? it sounds like the blades or the bearings are rattling.

Sounds like your Turbo has had its chips, be prepared for a big bill for replacement

That could be from the loose hose, as well. A noisy turbo would be accompanied by a lot of smoke out of the tail pipe. If you have babied this car, it isn't the turbos.

A blown turbo hose will result in a lot of brown or black smoke as the car tried to match fuel with air that isn't going into the engine.

Have you scanned for codes? I smell a clogged cat....

Since I have a turbo leaking oil, how much did the turbo repairs cost? I am having my TB done this month. Not ready to replace turbos yet but need to put aside the budget money.

In any case the cost of turbos replacement far exceeds the value of the car...
Book labor is ~24-27h

Value is in the eye of the owner. My A8 is eight years old with 185k miles, but is in excellent condition. I figure my cost of a similar "fun" car would set me back $25-30k (2-3 year old S4 or maybe even a little older RS4). So plopping $1200 into a TB job next week is just high maintenance. Brakes and rotors all around just set me back $1000 last month (but the last set lasted 75k). And if the turbos eventually go, then I figure $6-8k for K04s, injectors, piggie pipes and I have ~400hp; vs $3-4k just to replace the stock K03s. The only open question is do I need to upgrade intercoolers and should I pull the heads and rebuild valves, replace gaskets, etc to handle the additional power?

You don't need to upgrade the intercoolers but it will free up some more boost. Im running ko4's and just the bi pipe and some new dv's and there car handles the power well.

The cost for replacing both turbos, timing belt, and aux water pump was about 6000.

Turbos should outlast the car. Use good oil and change it regularly. Save your money for a trade in should your turbos go.

Question Turbo problems

My 2001 A6 2.7t was just diagnosed at 130k mi as needing 2 new turbos. Dealer estimate is $4800. Is it work repairing or would I be better off selling for parts and finding another one?
I replaced the timing belt and both water pumps a few months ago. The car runs fine otherwise.
