These are very common codes on this engine and is related to the intake and exhaust camshaft actuator solenoids. GM has had huge problems with the solenoids. Remove the connector and use an ohmmeter to check the resistance of both. They should be 5-9 ohms. If not, replace them. Replacing is the most common fix. BUT that all depends on whether you've been good about changing your oil. Both of these solenoids meter oil to the variable valve timing mechanism. If you've neglected oil changes, sludge can gum up the solenoids and cause these codes.

Detailed information on troubleshooting and repairing a p0014 dtc diagnostic trouble code which refers to a camshaft position actuator circuit.Missing: 525i
The P0014 is a cam phasing code. The phasing system is a hydraulic actuated phase shifting system and is vulnerable to dirty oil. If its been sometime since your last oil change I would recommend that you start with that. The control module turns off the MIL after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
The P1345 could be caused by the P0014. The powertrain control module monitors the correlation between the crank and cam positions and if the deviation between the two exceeds a predetermined amount it will set the code.
