CEL Code reading clearing - OFT only reads Engine ECU CEL
OFT will read and clear CEL or Engine check light code.
Note the OFT only reads Engine ECU codes it won't read Body computer or Auto Transmission codes. so it possible to get a CEL light and OFT says "No Codes" however it will clear all codes I believe. To read the other codes suggest you get Techstream and suitable adapter or a cheap ELM327 Bluetooth adapter and Android Torque app
I have a manual and never had issues before. I go to the diagnostics tab and check but again OFT says nothing is there, what am I doing wrong?? Any help is much appreciated!!

If you have catless header you should be on stage 2 tune as they are for catless header and have p0420 code disabled.
oft should read that code though
each time you flash the ecu is reset along with any ce codes
you might be getting a can buss communication code if your connection to obd port is not good that code the oft wont read
you can reset cel codes by diconnecting battery and pressing brake pedal, this will reset ecu .
