I just thought of something simple. Be sure that you have premium gas in the tank and that it's not old or stale. Regular gas will not run well in a Turbo engine and could throw a knock sensor code. If that's the case, put in a bottle of octane booster and top off the tank with fresh premium fuel. Drive it normally for a day to mix then pull the EFI fuse to clear the code 52. If the code 52 comes back, then more investigation into the wiring might be necessary.
