Ditto about changing everything... Dave, our electronics are not shielded from RFI, I found that out a LONG time ago when my 99 Olds Intrigue had an issue with the throttle going to 3000rpm while at the closest drive through (only) at a local bank. Happened twice (once shocking, second time intentionally to see if it repeated itself at that window, and yes it did). Since then, I used the inside counters OR used the second/third drive up (away from the building). The time my XF fog lights went nuts, Mrs and I were eating B-fast right outside the AFB, and a B-1 was low flying over the base. Saw the fog lights ONLY flashing (right outside the window) and went out to see why. No alarm, reset with FOB, no other reason. The post I made was commented on by another member who experienced the same condition (once as far as I remember). I happen to know RFI can screw with many systems, its one of those things that can and do happen more than anyone knows. Never observed this flashing again on my car.
