Are these P-codes?

I think you've got the MINI FC codes. You need a code reader that can read the P code. You'll want to purchase a Bentley Manual as it has all the MINI FC codes with their associated P code. It's just a lot to look through if you don't have the P code - as it's in order by P code not MINI FC code.
From what I found: 2845 DME Vanos Exhaust Actuator Movement Try cleaning your VANOS Solenoids - info here: MINI Cooper R56 VANOS Solenoid Replacement (2007-2011) | Pelican Parts DIY Maintenance Article 0x277D is P0302 Cylinder 2 Misfire Detected 0x2781 is P0300 Cylinder Misfire, Several Cylinders Bentley Manual where these codes came from: Mini Cooper, Cooper S, and Clubman (R55/R56/R57) - Books & Technical Documentation - Page 1. When was the last time you changed your spark plugs? Also, I have seen the 2845 code associated with timing being off and may be the issue due to the associated misfires. Do all the correct diagnostic work before assuming a timing issue. Clean the VANOS, inspect plugs (change if it's been a while).

I have an automatic 2010 R56 with 50K on the clock, It has shown code 2845 from time to time and suffered occasional stalling at junctions. I checked all the easy things, oil level, VANOS filter screens and operation, vacuum pump and exhaust camshaft position sensor and all fine. With low mileage and careful use (wife owned from new) I felt the VANOS unit and timing chain should be OK. There was a slight sound of timing chain rattle but nothing like the death rattle people describe. So I changed the timing chain tensioner. Not too difficult, just remove the airfilter housing and throttle butterfly body and then its easily screwed into the back of the engine. Its just a spring loaded plunger which is also pushed by oil pressure and bears on the rear chain guide. The new unit had a much firmer spring than the old one. So now the code and stalling have gone and the engine is a bit quieter. I also swopped over the exhaust and intake VANOS solenoids just in case I had it wrong. The latter step is a no cost option if you are struggling, both units the same and would show a changed code if one solenoid valve is faulty. The tensioner was also a lot cheaper than a solenoid unit.
