Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suggestion
Might have some thing to do with resetting itself if you've triggered the ABS, used to catch me out...

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi Guys,
I have been making the most of the recent weather in the C4S; i've been hitting the button to turn off the aids as soon as i start up. The car slides nicely before the 4WD gets a hold and impressively brings oversteer into an a neat four-wheel slide.
However, tonight on my drive home i felt the throttle being interrupted and the slide died. I glanced at the dash and it was flickering at me - something was stopping me!
There seems to be no drawn out procedure; if i hit the button it beeps and tells me ESP is off. I tried holding down the button but it beeped instantly once more. Am i doing something wrong? Is the car telling me it doesn't want to abused? I'm sure it's not done it before...
Cheers!
Happened again this morning, it's not like VAG cars where it's never truly off, is it? Very unlike Porsche though...
This morning i was on a large, empty roundabout and prodded the throttle (no problem), then backed off a little, reapplied throttle and i saw the light flashing away at me again.
Was the light on permanently before it started to flash?
If so I believe thats the automatic brake differential in action, and you can't turn it off. Irornically I was meaning to make a thread about it.
It's a 997.2, like it says in the title
So is it trying to brake individual wheels then or something? I remember when i forgot to turn everything off on my CSL once and i absolutely ruined the brakes within an hour on a track day as a result!
The 997.2 C4S has apparently got a locking diff, unlike the C2S. I'd expect it is the PSM kicking in when it detects you letting off the throttle. I'll have a read of my book and see what it says.
Is this in Sport or Sport plus mode?
Err yes, I knew that
ABD brakes the spinning wheel to send power elsewhere, there is not much in the manual other than ‘stops one-sided spinning’.
Not sure why you’d need it on a C4S, maybe it’s because it’s the girl’s version
It reads as though ABD stays on at all times. PSM should stay off unless a wheel needs ABS. PSM threshold higher in sport mode. That's about all I can glean.
Thats my understanding.
Normally these systems turn off at a certain speed, I know on something like a Focus ST it stops working above 25mph but I cant find any such limit for the 987/997.

Should have seen that coming!
Interesting. A little disappointing; i'd like to see if the speed makes a difference but not sure trying to get the car sliding above 45mph is the most intelligent decision.
Thanks for doing the research!
Yeah, it has to be provoked in a quite unsubtle way! I have wider tyres than stock too, but they are not good in wet so that helps. It is much easier and more progressive in the GT3.
This is a source reference. Confirm exact model applicability in the original material.
