So I was driving home from work a couple days ago and these two error messages came up and car went into limp mode. Pulled over and restarted car and errors went away. Came up again the day after so I took it to the dealer to diagnose. They said it was because of a leaking vacuum pump. Before paying $1500+ for repairs does this sound right to you guys? I did some research and it could possibly be a throttle body harness/transfer case issue.

It's a 2008 e70 X5 4.8i btw.

Thanks everyone.
