I bought a lemon - E87 116i help troubleshooting problems

Little backstory. I was in car search when this BMW popped up near place that i live. Went to a person to check car. Non of this problems (except heating) was existent at a time, problems was there but i did't noticed them. Car is with 116i n45 engine

1st problem with car that i didn't noticed was engine noise, like valve rattle. But problem occurs only on highway when car is not on load. f.e. when driving highway downhill around 3000 rpm. Problem occurs occasionally, can't hear it everyday. Loose chain, vanos? Is there way to check loose chain without opening valve cover? Can i test chain tensioner somehow? Test from ista+ vanos test (in attachment 1)

2nd one is with white-blueish smoke from exhaust. Again, it occurs occasionally f.e. city driving or when misfire than i get cloud of smoke behind me. and i got to add 1l of oil for around 800km. Found out that it could be oil separator, but i could not find anything on google about it

3rd is that misfires when driving slow. After misfire cloud of smoke is produced

4th and most annoying is blower direction and heating. Blower direction doesn't work, nor seat heating nor air recirculation, but i blower speed works, i can set it to any speed, but blows air(hot) only through defrost. I have manual controls with ac. Checked all fuses checked wires to FSU, nothing. and cold weather is coming fast. Can it be that FSU is faulty?
only shown errors on ista+ (in attachment 2)

Re-teach the flap motor positions and run a flap calibration. It sounds like someone has fiddled around before
