I don't know if my spoiler is working in auto mode although when I'm doing 70ish a quick dab of the button and it pops into view in the mirror, quicker than if I press the button when it is down, however, I have run it up to a somewhat more illegal speed and it didn't show. OK a few MPH more and it may have but I want to just know that it works as it should, not further risk my licence. It works perfectly in manual off the button and I have driven significant mileage with it at max, when I stopped it didn't go back to the park position. So, what operates the spoiler to the maximum height? Do both positions operate from the same unit? Is it a relay or other module? I have oiled the mechanism, Manual button operation is good but a little noisy.
