I knew that...
When the dealer didn't have any in stock and a long way to get there....I gave my spare up to my riding buddy for a warranty replacement. Knowing that we would have another one at the hotel in the AM two days later....overnight from Lynchburg....we were not worried. Who knew another EWS would fail??? The odds seemed to be in our favor. We all carry them now....especially since the price has been cut in half.
I am more annoyed with BMW Roadside Assistance!!!
