As for turbo rebuilds, I just had mine rebuilt by Turbo Lab of America for $650/each. I have yet to put them back in as my engine is also getting rebuilt by Ghassan after a rod bearing failure.

S63 - shouldn't the 2011 have the N63 motor? Also, wasn't the valve seal issues mostly related to the N63 and not the S63 as that was resolved in the next gen motor. OP - There was a lawsuit for the N63 and you should be able to get the valve seals replaced under this class action settlement at a dealer, but since you are over 100K, I believe there is a prorated mileage for the repair.
