This whole thing is a bit tough to work out as I am stuck in Seattle and I have my wife doing the diagnosis long distance. She's not afraid to work on stuff....but gets a bit frustrated when mechanical crap pops up.
Sent her with a tester and the battery was completely dead! She grabbed a new AGM and installed it, and everything lit up. Funny thing, while I was talking to her on the phone I could hear a clunking, turned out the spoiler was trying to lower but seemed to be stuck....just kept cycling......most likely why the battery was dead. Spoiler would keep trying to lower while car was off. Don't know the specific timeline of events, but when she put the battery in, the dash said "Failure Spoiler Control" and "System Fault Visit Workshop". Now the car has power, the spoiler continues to cycle, the left tail light stays on, and the rear trunk won't open.
To me it sounds like there is an obstruction keeping the spoiler up, but she couldn't see one (she lost patience for looking pretty quick although). But the weird thing is the tail light is on, which shouldn't have anything to do with the spoiler. The trunk could be locked down for the same reason the spoiler is up?
Does any of this sound remotely familiar to anyone? Seems like a good puzzle
