I have same problem. What is a vanos? what should i do?
2004 x3 2.5L 110k wants to start but stalls. if i press gas it won't turn, too rich. I did run gas down to bottom of tank. I'm bieng told I need new DME/ Computer. Codes 29B5, 28B2, 27A1, and 2796 so i'm told. My problem is a lack of trust as the mechanic only stands to make 100. dollars in labor and the part is 1500. then why is he calling me once a week for the job?
If someone can tell me what to do before i let them change my computer , i'd appreciate it.
