where in jersey are you...if you are not to far check out Orange county BMW i really like their service dept...and recently westchester BMW was purchased by ray cantena and their service dept has been kicked up a bunch of notches because of it... i have found both good but orange county's diagnostics pretty great....
if you are close enough and decide to go there pm me for contact pp and numbers
