I think my flap is frozen or stuck closed. My left pipe (single sided 428i exhaust) is frosty and ice covered (-25 to -30 deg C for the last 2 weeks here).
I am trying to get the valve open so that I can disconnect the electrical connector.
My question is, if I can't get the valve opened normally through the cars exhaust logic and vacuum, will the 'wire mod' open the valve as I tighten down and twist it in place?
