E320 cdi 2005 Code issues
Hello everyone, I own a 2005 e320 cdi and have had a number of issues since getting it that now I am attempting to get fixed now. I am suspecting that all of the issues may come from a problem with the PCM but wanted to come to the forums for advice!
list of codes:
p0243:turbo charger waste/gate solenoid
p2237: pump current connection of oxygen sensor 1( cylinder bank 1) has an electrical fault or open circuit
p0683: glow plug control module to PCM communication circuit
im also facing my cruise control not setting properly (as in I set it to 60 mph and it drives at 59 or 58, has gotten worse with time), and the car won’t go above 3000 rpm
if you suspect I’m entirely in the wrong don’t be afraid to let me know and to give your two cents on the matter because it may just be that I need to replace a few different things but I don’t know.
also these codes were taken with o Riley’s veriscan thing because I work there lol, thank you for reading and helping.

I am kicking myself that I didn't ask my dealer to code the Tele-Aid out the last time I had my CDI in the shop to get the SBC pump replaced.
That's all a long way of saying, I wouldn't worry that the Tele-Aid warning has anything to do with your engine issues.
I do have one question though, how often are you trying to push your engine above 3000 RPM? My shift points have always been in the 1800-2200 range.
