Chilliwilli: Though I have sold my x5 I still check the forum. I think Westchester BMW and BMW of Manhattan are both factory owned dealerships (I have dealt with Westchester BMW where I bought and service warranty issues on my former X5, and bought a bike at BMW of Manhattan years back).

If one honors the warranty I do not understand why the other won't. I would have Manhattan call Westchester and honor your warranty just as they did (West).

Good luck.
