How common are turbine failures on 997 Turbo?
I was reading a UK forum and one guy said his turbos failed and with some other repairs the bill came up to 18000 GBP.
Made me wonder - how often do the turbos fail on the 997 Turbo cars?
Did anyone here experienced such a failure?
What would be the expected reason for such a failure (bar not changing oil at regular intervals) - tracking the car? High mileage?
What is the cost of fixing a failed turbine? (Do both need to be changed or only the failed one?)
Just curious.
Another thing:
My 997T is 63k miles now, I do not track it and very seldom even spin it up above 4000rpm, but i do occasionally put the pedal to the metal in 3rd gear at about 2000-2500rpm to hear that "brap!" noise and feel the push once the turbos spool up at ~3200. That also produces a puff of smoke out of exhausts at exactly the brap-moment (according to my gf, who tries to hang on behind me in her Z4 3.0Si). My car has aftermarket exhaust with 200cell cats, is the little puff of smoke (not blue, not white) normal on such acceleration runs?

Not common. I had to replace a turbo on my 2007 because the VTG actuator was frozen solid and replacing it did not cure the problem - the issue was corrosion from sitting too long so it was just easier to replace the turbo as a whole unit. Bought a nice used one for 2500 and called it a day. But no, not a common problem.

What does "too long" mean in time terms?
Mine sits in a garage on a trickle charge and I drive it maybe once a month just to stir the fluids and keep the tires round.

It is quite common in the UK I can confirm, due to corrosion on the housings from cars that are used in anything but dry conditions. I am in the process of having to buy and fit 2 new units due to this exact problem. I have spoken to a number of the best known turbo repair specialists in the UK and they are seeing more and more come in with failures due to housings corroding, getting thin and then blowing. I will update my own thread with the details as I do the DIY on my problem car lol
