C63 S COUPE
Possible Need of a New ECU?
Hello everyone,
So I’ve been having this issue on my 21 C63s coupe where when I’m on race mode and I’m pushing it, 3rd or 4th gear and I downshift to say, 3rd gear, and then gas it, it will turn on check engine and go into limp mode. The code I get is P0103, which is a misfire. Took it to the dealer and they got a fuel temperature sensor code which is P0181. They told me that Thurber had an issue like this where they’ve had to replace the whole ECU bc of a shortage in the ECU that causes misfires. Anyone experience anything like this before?
