Something got done....we all just have NDA's
Think about all the times BMW or an SA has said,
"Never heard of that before"
"You are the first person to have this problem"
"It must be the way you drive"
If not for the out spoken some people may have actually bought that malarky.
However, facts and actions taken should be part of the process, not all shouting.
That is how I eventually resolved my situation.
PPXYZ please tell us what another mechanic, lawyer, BMWNA representative, etc has said with respect to this situation. We want to help, but your approach does not make it easy
