Code:P0491-Secondary air injection system insufficient flow bank 1
Hi all,
I got a P0491 Check engine code, which means “ Secondary air injection system insufficient flow bank 1”. On my 2008 B200 Turbo 2008.
Does anybody know how much fixing cost (parts) and can I still drive with this code as Engine light is on.
Thanks.

This is a reasonable summary of what brings that code and may help.
