Joining the Blown Turbo Club

[Gonzoe11]

Just wanted to share. I know I’m not alone here. I’m suddenly seeing a bunch of you in the same boat.
I thought I’d share my symptoms here. Last month I was driving the kids to school early morning and had the S7 lose power and stall while merging onto a busy road. The car eventually started after a few attempts and I thought nothing of it.
Fast forward 3 weeks and my wife in her Q5 parked next to me is telling me my car sounds terrible and points out a clicking noise at idle.
The next day my car stalls out after a rough idle. My idle was fluctuating between 500 rpm and 1100. The stall and rough idle continued the next day and eventually the S7 died on the way to drop off at my shop.
Had it towed and diagnosis came back blown turbos. My tech told me the front of the shaft seemed functional with some minor scoring on the inner wall of the housing. Eventually he was able to access the back of the shafts and the driver side rear was cracked.
Anyway, I was able to locate a used set of turbos from a member here which saved me a good amount. The part quote for the kit including the turbos, gaskets etc. was $5000. The turbos were $4100 of that. Ouch..
The car is getting fixed and will hopefully be ready early next week. Now what?
I’m debating if I’m keeping her longer or move on. Lately my driving consists of 25 miles a day of mixed highway and some back road twisters but the car mostly sits in a lot. I’m thinking, time to move on but I know I’ll miss the power, comfort and sportiness of the S7.
Anyway.. I vented. I hope I don’t see any more posts of blown turbos.

how many miles on the car?

[Gonzoe11]

42k miles. Stage 2. But never run hard.

Did you have any of the turbo campaigns done? Any previous work on the car that would involve removing the turbos and reinstalling? Also, what year?

[s4nicetry]

Bummer, sorry to hear. Are you saying you got the used turbos for $4100, or was that your quote for a new set? also would you mind going into the 4.0TT sub-forum and putting your info in the blown turbo poll?

I'd keep the car, the money is spent so you know the turbos are good now.

Good for how long? If we're replacing blown turbos with the same turbos, will they not eventually fail? I need mine to hold out until September when I deploy. Upon return, I may have to bail on the S6, which is a shame, because Stage 2 is pretty sweet. I'm at about 63k miles, about 35 of which have been tuned, and the last 5-10k of which have been Stage 2.

The problem isn't with the turbos, it's gotta be something else causing the turbo to fail prematurely. There's a recall on oil lines to the turbo, did you do the recall?

I don't believe i've had any turbo work done. Only recall/TSB I recall receiving was related to the coolant system, and I believe all the dealer did was change the software. May have to look into it when I get back from this trip.

[Gonzoe11]

I haven’t had any dealer campaign done on my car. $4100 was the dealer quote for a pair of new turbos. Was able to pick up a set for $1500.
I didn’t realize there was a poll going. I’ll look for it.

Gonzoe, out of curiosity, how often have you been getting oil changes and which oil have you been using?
