Being a septic skeptic I could say they missed the bit out about "plus we don't make any money if you fix the damaged one rather than replace it" but I am only playing the devil's advocate... While that is the case in a lot of instances, I doubt it is in this case...
i have read part of this post, & saw the mention of part recall? so is my i30 in need of another recall part?also being profoundly deaf i won't hear the whistling turbo ( scary )
I guess the problem began to surface a month or two after I ran the car too hard up a steep and windy road on a hot day and towing a trailer full of camping gear. It then started to overheat badly before pulling over and allowing it to idle and cool down to normal operating temps.

It's interesting to note that it was overheating - was this apparent via the temp gauge?I sometimes wonder if the gauge is of much value - by the time it rises it's too late. (particularly if you have a sudden loss of water)Some time ago I posted and asked if anyone had ever seen their gauge anywhere above normal and didn't get anyone with an example.
On 2 occasion I've had the temp gauge rise to the other side of the middle mark. Both times was when towing the caravan up the motorway in the Alps on very warm days, ca 30 ºC towing 1400 kg.Both times the temp rised to the point where the engine lost power, controlled by the ecu, to protect the engine I guess.Once the engine have cooled of, the power is back.

You are very relaxed about the loss of power - I would have been more worried. Maybe I'm getting too old!
Actually, I find it a very nice feature, that the ECU reacts on the hot engine with cutting the power. Other cars just get hot and suddenly the water boils :
Would have been interesting to know what they costed it at! Not a common warranty claim fortunately.
The turbo whining noise is due to a problem in the variable vane part of the turbo, which is non-serviceable. In other words there is no way you or the service department can fix this, other than getting a complete new turbo, or getting a good second-hand one. I had this occur in mine and the noise got louder and louder as the months went by. And yes it started to sound like the cops or ambulance were on my tail. I guess the problem began to surface a month or two after I ran the car too hard up a steep and windy road on a hot day and towing a trailer full of camping gear. It then started to overheat badly before pulling over and allowing it to idle and cool down to normal operating temps. I suspected that over working the little turbo may have caused the variable vanes to warp slightly due to the heat. This was further confirmed when I had my mechanic remove the turbo and establish the main shaft bearings were still in perfect shape and well within tolerance. Unfortunately I couldn't claim a new replacement turbo under warranty because my servicing was not regular according to the service book. So I decided to source a replacement second-hand turbo from the wreckers with low kms for about $1200 (i think) plus r&r. The car has now done over 100K on the second turbo and all is still good with.Moral of the story? If you're starting to hear the whining sound (whether idling or under acceleration) it will be the variable vane component beginning to fail and is a non-serviceable l part. And if you're servicing record is impeccable then you should be able to get a new turbo under warranty. At the time when the turbo whining was going on I was warned that if I leave it too long the variable vanes might break completely, thereby sending shrapnel into your engine, and well...I'm sure you know the rest. Mind you the turbo was whining for several months before I decided to change it.Anyway that's my 2 bobs worth.
