hi i have a 2007 m5 and it was sitting for a couple years. I had the battery replaced and registered, and I had a light and limp mode. I took it to the shop and had both throttle actuators replaced. When i drove it, it drove fine but if i let it idle for 20 seconds at a stoplight, the check engine light comes on and sometimes goes into limp mode. if i restart it and drive it goes away unless i let it sit and idle again. I have replaced all the coils and spark plugs and Maf sensors. It helped but didnt fix the issue. the other thing i notived is my hud stopped working. Could this be a software issue? any help with this would be really appreciated as I am already heavily into it budgetwise.

You need to use a computer and ISTA software to pull whatever codes that your car is showing. Otherwise, you are just shooting in the dark.

Good luck,
