since saturday i kept getting the idle control system rpm higher than expected code, but then today 2 more showed up.
on saturday i did an oil change and fuel filter change. but i cant seem to figure out the idle control part. the plugs are also fairly new ~ 4k miles on them gapped at .032. the car is 1.8t quattro with apr +2 flash.

 

These are just guesses...

Have you cleaned your MAF? I would try that first....Clean it with some good stuff, it's the easiest to do, then go from there...since you put in a new fuel filter...most of your codes (and others) sometimes show up when there is a bad/dirty MAF....

P0507 maybe crank case breather valve or vacuum hose somewhere...
P0300 usually means coil pack or plugs...take plugs out and look at them...you can also move coil pack from cylinder 1 and put it in another cylinder, clear the codes and see if it follows...if it does, coil pack is bad....

Again, I'd start with cleaning the MAF, clear codes and see what happens.....it could be bad too, but cleaning it correctly generally helps...there's a write up here somewhere.....

Just trying to help....

 

i found my vac/boost leak... very audible at idle and it was between the throttle body and intake manfold
