Back from a 2 week vacation after 1000 miles on my 'new' 2007 GSA and it will not start. No engine check or warning signs, everything looks like it will start up as usual. The fuel, lights, Neutral and other electrics on the display work, so its not a flat battery. But the starter button has no effect. No whirr, no click, just silence. Can't take it to the dealer, nearest one is 3000 miles away! I have little to no maintenance experience. Any thoughts or suggestions? thanks.
