Thanks 4th Gear for the reply. I don't know how to find an independent BMW garage. I am concerned, most will say they are capable. I already went through one who said he was capable to fix any car, but it appears he was learning. I would be happy if I could just find out what the default settings are, what is available before going to a mechanic who has the bi-directional equipment to effect changes. Any tips how to select a garage and where to find the default settings would be much appreciated.
