Spoiler Won't stay down
Spoiler Won't stay down
So the other day this started, my wing is down and when backing up or going forward, the moment I hit 5mph it will pop up and the spoiler light will flash. No engine codes and did an ESP reset, also battery is a year old and reads 12.6V
Any suggestions very much appreciated!

Re: Spoiler Won't stay down
I'm going to play with the wife's roadster.. as in pull a sensor out of position and see if it goes to ESP error with the sensor immediately or when rolling. I know my cars problems were jumped on as most likely speed sensor or battery when I was new here (merely started car and lights-spoiler-action). Tried wheel sensors.. no joy... battery finally went belly up about 8 months later.. same condition. Even though at the time I had noted ABS error too.. it was ignored as a symptom in this. I'm really feeling ABS pump and or module in mine, since the yaw sensor and clock spring are ESP related actions. Might try to get to it Monday if we get back from Nascar race early enough.

Re: Spoiler Won't stay down
Connections are good I just installed a new ground on the battery a few months ago as part of the big 3 wire upgrade. Battery reads 12.6 and my sub amp in the trunk reads 12.59V using 4awg wire, so I think the battery is fine. I'll unhook it for a minute and plug it back together to see if that resets something. Still no engine codes.
Re: Spoiler Won't stay down
If there are any codes they would be specific to the mfr. code scanner not that one. When I had abs, BAS/ESP lights on and spoiler up, I looked for continuity on all the wheel sensors, checked all the grounds. Checked CANB buss CANC buss all looked good, all modules were talking on the busses but till I had the codes read with the Mfr DRBIII scanner at a dealer could it get fixed. Bad BAC & wheel sensor.
The only symptom is the spoiler up @ 5mph? No lights, no other symptoms? Seems like the ABS BAS/ESP systems do a spot check just after you are underway but I thought that was at 15mph.

If the engine was not up to temp might be why these were "pending."

Re: Spoiler Won't stay down
Yeah I have an alarm on Torque Pro to run when the engine is at operating temp. Codes still popped up. But they're pending and I haven't messed with Torque in a while. I googled pending code and if anything shows up out of the ordinary it will log it for 40 drive cycles as a pending code and if the event replicates again then it will be an actual fault.
Re: Spoiler Won't stay down
Code still hasn't come up but I went and had the battery tested and it came back good. I'm very certain it is a speed sensor but I have no codes showing that is the problem. I guess this weekend I'll have to test them out with my multimeter. I would just swap them all out, but at $50 each I would rather wait and find the fix.
Re: Spoiler Won't stay down
So the issue fixed itself overnight. Not sure what tricks the Ghost in the Machines are playing on me. Maybe just some more radio interference since I live on an Air Base. Last year we had a certain aircraft here and whenever it flew over the base my lights would flash but my alarm siren wouldn't sound. oh well, just glad I'm not shelling out money this time.
