2013 750Li - P054D Fault Code?

[srd6]

Hi all - just picked up a 2013 750Li which has been displaying the P054D fault code for "Cold Start B Camshaft Position Timing Over-Retarded Bank 2".

The car runs without any issue at all and there is no loss of power, speed, etc. and isn't in any kind of "limp mode".

I'm not a mechanic and not particularly mechanical with this level of car (I have '70s British cars which I know better) but I have read that a solenoid valve replacement is one fix in this case?

Any thoughts?

Otherwise I am very happy with the car and plan to do what is needed to keep her running well on the road.

Many thanks!
