Re: air intake swap, now cel on
I'm no expert in code reading, but my inclination would be to capture your list (as per your graphic) and then reset all your codes.
Run the car for a few miles and see what new ones come up and post that if different.
It is my understanding...some codes are originated by the act of disconnecting and reconnecting "stuff".
You could possibly try a Throttle body reset after that as well...and repeat above to see if things changed.
Note: The SLK230 preceded the SLK32 - the SLK32/C32 was the format on which the Crossfire was built after Chrysler bought AMG.
TB Reset (SLK230) from here
Open the door, put the key on the ignition, close the door.
Move start switch into position "2"
Press the gas pedal to the floor... past the kick down point
Hold the pedal there for 15 seconds
After 15 seconds while foot still planted, turn the key off but do not remove it
Release gas pedal... Wait at least 2 minutes while not touching anything in the car, don't open the door even.
After the 2 minutes start the car and drive off normally...

The throttle reset is not a miracle cure for anything except a sluggish throttle from what I have seen.
Surely the Crossfire has the SLK320 as a main parent, Mercedes purchased Chrysler not the other way around.

Re: air intake swap, now cel on
well put in new gas peddle and did reset but didn't fix it . removed cover on throttle body and cleaned . then did 5 min battery disconnect and then another peddle recalibration . so start it up, no p0123 code . drive it and now it runs like a na car . supercharger wont kick in but it doesn't go into limp mode anymore . you can throttle all the way and it just runs like a car without a super charger . but when you get to the stop sign and then accelerate again the throttle works fine , so the problem where the throttle would go unresponsive is gone .
torque pro shows the throttle % only going to about 50% so i'm guessing throttle body is bad ? ordered used throttle body to swap out , so we'll see .
on the way home cel came on checked it again , no p0123 code but lots of others . now i'm really confused .
