@user_1212754 Oct 27, 2022MemberHi! My 2007 120i M Sport BMW has had a half check engine light come on, and experiences a loss of power upon start up. Code says VVT however the mechanic I took it to said he can’t identify what the issue is as the car drives fine and it seems to be the code that’s causing the car to go into limp mode.The problem is on start up, it sometimes drives completely fine with full power but then other times not and will go into limp mode. It seems that if the code is cleared, no issues.Any ideas? Is it a computer issue, sensor or engine issue?

It is difficult to suggest something, as an option, a problem with sensors, possibly with wiring and connectors to them, or maybe with a timing drive in general, you need to look for.
