W203 went into limp mode :(
Hey guys, this is my very first post!!!, i recently replace my EGR valve on my 2005 W203, and a couple of day after replacing the EGR my car went into LImp mode, i hooked up my scan tool and ran a quick test and P0600, P1999 as well as P0720 code popped up after the car went into limp mode, kind of lost where to start checking since i already replaced the conductor plate on the car 3 months ago, i dont know if the EGR is what is causing the car to go to limp mode or im having electrical issues, i checked the battery voltage and battery voltage is at 12.5v, the car has 165,675 miles if that helps in anyway

yeah I check the harness and no sign of any tears or damages, I also forgot to add the car also gave me a P2310 which is the first time I ever since this code, so I don't know if that code is what is making the car throw the other codes.
