Fault codes, cruise control? I don't have cruise control :/

[G3 NYX]

Hey guys, I got a print out of all the codes on my car, they have been cleared for now, but I was wondering what caused them? Especially the cruise control one, since my car doesn't have cruise control...

DF058: Downstream oxygen sensor circuit
DF135: Brake pedal sensor circuit
DF030: Fan unit high speed circuit
DF110: Destructive misfire OBD fault
DF110: Destructive misfire OBD fault
DF235: Cruise ctrl speed limiter, fault of the two brake pedal contacts

Any description of what's actually going on in my car would be great
I had the spark plugs changed which solved the destructive misfires.

Cheers

First one is the post cat lambda sensor.
Second one is the brake pedal switch (have a look in the guides, it just needs adjusting) also the cause of the last fault.
