Some questions about a few codes

Codes are from my baravian code reader. Looking for causes and solutions

Table 19
8f: dm-tl leak detected
A8: coolant thermostat jammed opened
1d: ignition coil #1 (this one seems straight forward)

8f- leak in evap emissions system (could be loose gas cap or a vacuum leak at evap solenoids at rear of engine compartment)
a8- replace thermostat
1d- you answered it. Swap coils and if misfire moves then you know you have a bad coil, if it stays you have another issue (like fuel injector, but hey how often to bmw's have problems with fuel injectors? If it was an Audi then i'd say coil and injector .
