If you like a refresh of your turbos you will have to pay for it especially if there is nothing wrong with them, prevention is cheaper than cure but at the same time your turbos could last another 35k so why do you think a manufacturer would refresh a set of turbos if there was nothing wrong with them for free because there has been a number of reported failures and what about the hundreds of set still running with no issues.
The best example of this is BMW. Its vastly known that they had wategate issues with wategate rattle and BMW didnt replace all those turbos that were working as designed, but they did replace those that failed. There are plenty of 335i's out there with over 150k miles still running there stock turbos.
If BMW replaced every set of turbo attached go every BMW they would go out of bussiness if they were a small company, but a company like BMW could survive that yet they still choose to only replace the defective turbos.
