2007 ACURA RDX

RDX produced the DTC P2263 and P77. I have the 2007 Acura Service Manual, I followed the instructions and replaced the air filter and completed the idle learn sequence. 2 weeks later (approx 750 miles) the codes registered again. This time, the air cleaner is new, so I checked for leaks and proceeded to the idle learn sequence.
After the first set of codes, I took the car to the Acura dealership. They stated that my turbo is failed, yet I still have boost when I drive it. When they told me this, they stated they could hear my bearing going out. Since this has come up again and I wasn't convinced that the turbo is failed or at risk of imminent failure, should I be concerned now? What would I be hearing if my bearing was going out? I have read as many posts about this as google will provide. What do you recommend?

I agree that this sounds like they are picking up on something that may fail in the future, but I did not listen to it. So, if the bearing is failing then you will hear a growling noise coming from the turbo and as soon as you hear this then you want to get it taken care of because it is going to fail.

I am going to attach the testing that we need to run through for this code but if the turbo has a noise as well then that is likely the issue.

Here are a couple of guides that will help with bearing issues:
