I need this part as well, mine just failed.
Fuses all intact
BAS sensor is on dash, ABS on dash.
spoiler will go up not down. Got it to go down twice and then popped back up.
up down Switch on dash not doing anything only flashing red.
took a wrench and manually lowered by turning at the blue connector. And unplugged everything at the spoiler.
top won’t drop now either.
I’d keep driving around with Christmas tree dash if the top would drop. Performance not affected. Braking system not as nice and no traction control but if the top would drop I wouldn’t care.

need new replacement part for spoiler if anyone knows please send a link !
