VANOS help!

Hey Guys,

I need a bit of advise. I constantly and randomly get the following error codes. F31 320i xdrive (N20).

============1==============
P0015
Raw code: 0015
ECU: Engine control unit
Status: Pending
OBDII: Camshaft position (CMP) actuator, exhaust/right/rear, bank 1 - timing over-retarded
BMW: "B" Camshaft Position - Timing Over-Retarded

============2==============
130308
Raw code: 130308
ECU: Engine control unit
Status: Pending, Confirmed, Test failed since last DTC clear, Test not completed during this operation cycle

============3==============
120408
Raw code: 120408
ECU: Engine control unit
Status: Pending, Confirmed, Test failed since last DTC clear

The timing set had been replaced 10k miles ago. So far, I've replaced the following:
1. Fresh oil and filter
2. Replaced exhaust vanos solenoid
3. Swapped the timing crank sensors around

None of above fixed it. Any ideas where to go from there?

0x130308 VANOS, outlet: control error, position not reached

0x120408 boost pressure control: Shut-down as a consecutive reaction


Does this car have a rattly timing chain? Is it possible it had slipped timing?

Thanks for getting back. The timing chain was replaced approx 10k km ago, and it was running fine, so I don't think it's causing the issue.
