Wifed parked in a parking lot, electrical system goes haywire. wipers start going, every known imaginable failure displayed, transmission, engine, srs, awd, ..............
She hits SOS, apparently uploads codes for fault, told one hour for pickup and overnight storage at tow company as everything closed.
I go pick her up. Switch off the car and restart, all the errors and the wipers keep going. Leave the car there, figure I can just have it towed Monday.
Go back after 4 hours, everything works fine, no faults, check ok. drive it home.
It rained 3 days this week and I had the windshield replaced last week and sunroof adjusted. Check both side storage compartments and wheel well, bone dry. I had the ecu or idrive replaced at 12 miles.
