I would replace the MAF sensor and then clear the codes. Drive it for a while and see if the check engine light comes back on. Does the engine seem to run okay?

With that many miles I would remove the inlet or outlet pipe from the turbo and check the endplay for excessive movement. This guide may help:

Can you hear the turbo spool up? Let us know what happens and please upload pictures or videos of the problem.

Can you hear the turbo spool when under load? I would check the air filter to make sure it is not plugged and if not change out the fuel filter.
