Had the p0448 code pop up the other day. Took it in, they checked the wiring and replaced the solenoid. Code stayed away for two days. Today, it has popped up. Just wondering if there's any insight on this? Haven't taken it to the dealer as I don't want to miss work over this but I see I may have to if the whole needing an ecm reflash thing is true. It's a 2019 sport with 94500km on it.
