So I went to my local dealer to get a "between interval" oil change before the holiday weekend. After waiting for a while i was informed of a "problem". Feeling a bit nervous I was escorted to the service bay and shown that the oil drain plug is too tight and won't come out. Another BMW center did the last oil change so I guess they used an impact tool or something because after 2 turns it just won't budge. The service tech said he didn't want to risk damaging the oil pan threads so he recommended I contact the other dealer.

I plan to contact them but I'm assuming they won't play ball and deflect blame on something else. Anyone have any experience in successfully retracting the plug without damaging the oil pan?? Any help is highly appreciated.
