I swapped the solenoid twice. Code keeps coming back and it goes into limp mode. Not sure if 0447 is related but from what I’ve researched it’s not. I did have some other lights on vdc and slip, brake light all coming on but those went off after I took my car in to have the exhaust fixed. They must have cleared the codes or flashed the ecu or something, I guess I should have asked but at the time I was like ok good, some lights are gone, but idk if this is related to the problem now… all I paid them to do is weld the exhaust together at the back flanges, they had rusted out before the muffler.

Any advice? I’m bout at wits end with this thing. It’s a 2009 g37x coupe. About 144k miles. Oil is fresh. Thanks for any help.

 

Ever figure it out
