2008 Mini R55 Clubman VANOS

[mkmini]

Hello all. I have a 2008 Mini R55 Clubman that I've recently had a lot of work done on for various issues.
Currently I'm still getting 2 VANOS errors. The 2845 VANOS Exhaust Activation Movement Error and the 287D VANOS Inlet Actuator Movement error.

I have recently replaced both Solenoids(Exhaust and Intake), oil pressure sensor, thermostat housing, CAM shaft phaser gear, Timing Chain, spark plugs and coil pack. All parts have been OEM from the Mini dealer.

I was going to try replacing the VV Lift Electric Shaft Actuator next however my local Mini dealer claims they have almost never sell that part which sounded a little surprising.

Any suggestions on what else I can do to eliminate these error codes?

Thanks.
