Hello,
I have a 2010 740Li with N54 engine. The car was always going into "limp mode" with drive-train issue. The car becoms almost undrivable. After diagnosing it, it threw 110001 and 11A904. I replaced the high pressure fuel pump. Now the issue is almost the same but the trouble code is 120308. I replaced all the vaccum pipes around the wastegates. I have confirmed the I have no issue around the intake filter housing. Any suggestions?
Thanks in advance.
