I've confirmed that my issue only happens when the heat is over 32 degrees. It was doing it just about constantly at 36C the other day, and we had a cool front with rain come in yesterday. I drove the car about 50km and was on the throttle hard lots of times (yah back road hooligan idiocy, had to get it out of me). It didn't error once. I think the pump has weakened in mine and it doesn't react fast enough when I accelerate hard, so the ECU panics. It could be a sensor malfunctioning because of heat, I guess.

I'd be really pissed at that dealership Steven. @#$%

 

yeah I gave them a bit of a talking to

 

The rear spoiler deploys automatically at ~73 mph and you cannot see it in this position from the rear view mirror. You can't see it in your side view mirrors either unless you specifically misadjust them so as to be able.

If they provided you with no estimate before conducting the repairs, unless you signed a "whatever it takes" disclosure, then I suspect they have broken CA law. (That would be the case in Mass and I doubt CA has less-"consumer friendly" laws governing repair than Mass.)

Leaks can, very much, be intermittent and completely not in defiance of physics.

How did you verify that the system works or doesn't work? Do you have your sideview mirrors adjusted so as to be able to see the rear wing in its undeployed position? Did you mount a go-pro to the front bumper cover so as to be able to see the splitter deploy?

Are you able to manually deploy the wing and splitter at any temperature or only below 32°C?

 

I have driven it 3 times since it happened and it hasn’t errored since. I can see in the side mirrors that it has deployed over 73. I’ll keep checking and monitoring. My car is still CPO’ed so that’s a little relief.

 

Note that in my case, the active aero would deploy the first time after an engine power cycle. But, *on the same drive* once it returned to rest position if I then passed the deployment speed again, it would not deploy and I would get the error.

It appears that the MFD-displayed error will trigger with any aero fault. If it thinks the front splitter isn't deploying it will not raise the rear wing.

It *may* be that on the first deployment the splitter didn't deploy but the wing did. I don't know: no go-pro mounted to the bumper

The aero always worked when deployed manually. IIRC, it would not deploy automatically in Sport+ mode.

 

I didn't get the error. Regardless of whether they did or did not deploy, my issue is the error. My car has always deployed the spoilers on the button as long as the ignition was cycled between errors. And I've left them deployed for a few days just to be sure that the front spoiler was still pumped full of air and stiff. It was.

 

same here...left it deployed and filled with air for days and then it randomly pops up there or and then you cannot deploy it again until you restart the car..

It started happening when I got the car wrapped and they took the front end off...I don’t think it’s a hole in the bladder because it wouldn’t stay inflated for 3 days...I think it’s probably a kinked or loose airline...or the control box for the system got damaged during the wrapping process....

 

This message showed up while i was getting on a highway ramp but going faster and faster. I dont know if
i was going fast too fast and the car didnt have time to respond.

 

When it works correctly it's as fast as it needs to be. Believe me. I did plenty of 'on ramps' during 2600 km of ED.

 

Still monitoring and no recurrence of the issue despite several trips to 75+. We shall see..

 

As I say...they come..they go
