i'm getting secondary air system codes on my 1998 528i. the codes are
>secondary air system Cyl. 4-6
>secondary air system Cyl. 1-3
i replaced the secondary air system pump and control valve reset the computer. it was ok for about 300 miles then the check engine light came back on. i tested it with the scanner and the same codes appeared. i'm in NYC where we had some bad weather recently. the temperature was at a freezing point for the past few months could that be the problem
can anyone help me out. what should i do first to check what could be the problem. i don't want to spend another $250 for a new pump just to see if this one works.
someone please help!!!
