Includes turbo & manifold. Not sure, my guess its aftermarket? But now the check engine light is on. Any idea why?

Possible suggestions can only be added after you post what is the error. "I have check engine light" is meaningless as there could be huge amount of issues behind that, related and unrelated.

I'm sure there are instances where the turbochargers last to 150k miles, but it seems most have the manifold crack issue even before 75k miles. Proper maintenance and care can definitely extend the life of the cartridge/turbine part of the turbo, but there is little you can do to prevent the manifold from cracking since it is just a poor design.

Yes! you are correct about manifold cracks. I am working on my second Evoque that I bought non-running, both 75k-ish miles and in both the heat-shield over exhaust manifold was covered with carbon deposits i.e. manifold had cracks.
But this does not warrant a 10k turbo replacement. Phessio Turbo website sells just a manifold, a one piece cast iron manifold for $200 + 80 for delivery, at least to NJ where I am at it is $80. I have already replaced one and just received another one for a second car.
First car needed a headwork so pulling a turbo was not an issue, second will need a whole engine so again, pulling a turbo and replacing a manifold is not going to be a challenge.'
But regardless, whatever it takes, whatever it costs to pull the turbo from the car and swap the manifold, let that be 1k, 1.5k that is 8-10 fold less then dealer had quoted.

Thats CRAZY!!!
First of all, stating a mileage if asking a technical question should be a must. may be Admins can add a little banner-reminder for everybody.
How many miles on your Evoque? Assuming owner keeps up with good quality oil changes, these turbochargers can last well in to 150K. What is the issue with the Turbocharger? Did they elaborate? or just said "give us 10K"?
