FUSE #7 had a lot of corrosion. we cleaned out, reset everything. drove car, was fine. parked it, drove again for less than a mile, went over railroad tracks, car died and ASR light went on. restarted car, asr on and in limp mode, drove back and parked. Restarted car, no asr light, but EA module was noisy. tapped on it until the noise stopped, and asr light came on. (we had previously tried a new EA, but there was no difference). This is the first time we have ever had any noise.
