Howdy,

I've occasionally noticed this car will flash the stability control light when cornering (sometimes in the wet, sometimes in the dry, typically on a long corner). It's strange since when it flashes the cornering isn't anywhere near engaging any kind of wheel spin or slip... yet it's never cut power. Yet.

This morning I was getting on the freeway and going around the corner to get to the onramp and all of a sudden the car felt like it was in limp mode. I looked down at the dashboard looking for the CEL or other warning and all I saw was the stability control light flickering. I pulled off and waited for another code or misbehavior of sorts, but nothing showed. For my sanity's sake I restarted the car, and it behaved fine on the rest of the way to work. (car WAS at operating temperature, FYI). I wasn't even flogging it! I swear.

I have one of the first RS's and I'm just under 30k miles on it (yeah... I know... she gets driven. Everywhere).

Thoughts? Wheel speed sensor? Overzealous stability control? It was in sport mode (where I spend 99.999% of time).

Thanks y'all.

I should add I had traffic behind me and I could have been rear ended from the sudden loss of power. WTF.

I wouldn’t suggest it playing with it on freeway on ramps, but have you tried fiddling with the various traction control/esp options.

Even in sport mode they both interfere. Iirc, one press is less nanny, hold and press is no nanny.

Play with it on wide roomy roads at first. =D

I've had this car for nearly 30k miles... and I've gotten it sideways with all the nannies engaged and no issues with cutting power. I was NOWHERE NEAR losing traction today... so strange.

Hmmm I?ve definitely felt the brake-based torque vectoring keeping it in line, but I don?t think mine has ever cut power on me either. It?s intervention does seem to vary depending on the tires/conditions. On summers, I only ever got a few degrees of oversteer in sport. Last week I took the same turn in normal with my new ?winter? all seasons and was surprised by a big 30 degree drift.

Overall, the ESC seems unpredictable, but I wouldn?t worry too much unless it is a reproducible problem.

Dunn I’ve had the same thing a while ago. I drift and slide the thing all the time, but I have never had the lights flash on (since I’m in the appropriate mode). Doing a road trip I was in a 130kmh sweeper right, it was wet. Just like you describe I was absolutely no where near actual loss of traction. I even had the snowies on. It didn’t cut power, But the TCS light started flashing ad I let off the throttle. Such an odd thing and has never done it since

 

[rdriggett]

Can confirm OP's issues, took this off ramp a bit faster than a normal person but no where even near the limit and the TC light was flashing on and off without losing grip.

That's what you may think but the RS works on a different real algorithm and probably saved you.

There is the nanny RS which will go into limp to protect you and then there is the death mode full nannies off which I don't recommend.

Safe driving..
:thumbsup:

I find if you are on a bumpy road or cornering hard enough to lift an inside rear the esp will come in quite drastically if esp is on.
Especially if you are on cold cup 2s.

It was just the lack of power from the 91 octane crap you are feeding it that made it feel like it was retarded.

HIGHLY doubtful. As I've said - I've had this car for nearly 30k miles. I know it and I know it well. I've experienced the nannies kicking in when they should have. I was WELL within limits. The weather was dry, not terribly cold, and the car was fully warmed up from ~20 minutes of driving already.

Love that California gas. Not the issue though. :facepalm:

I love these 270+degree corners! Way too much fun!

I drive in Track Mode but when I switch to Normal suspension. That's should be the same to Sport mode plus one press on the ESP button (Sport+ custom mode some call it). Without that "one press" TC/ESP will mess with my driving several times at least on a normal drive (I'm kind of a rough driver, maybe).

But when it rains.... Oh boy do I have fun... that's with the same mode but LONG PRESS on the ESP button for a no-nanny experience.

I have experienced this recently as well. Started happening around 30k miles. Once it started happening, a code was thrown and the car would no longer allow me to put it in sport mode. I took it to the dealer and they eventually just replaced the awd module. I still find that this is happening though. And there are no codes getting thrown but overall in fast turns the stability control kicks in and the car just feels like it's gonna go off the road. I'm going to take it back into the dealer. I think it could be that the front tires are older than the rear. I had the rear tires replaced after the one tire got a slow leak in it.

Welcome to the forum. Get an alignment from a specialist shop. I'm surprised that this has not been mentioned yet.

Keyword = "specialist" shop...

 

[ccopeland3]

If someone still out there with same issues: My RS was doing same thing. Got alignment (no specialists around me) at dealer. No help. Front tire tread was
less than rears. Got new fronts and problem went away.

If you want to experience it, put the car in drift mode without turning off the nannies completely. Drift mode will fight with the nannies and it's both hilarious and disappointing. Drift mode will let the rear end kick out, then the nannies will freak out and overcorrect to put it back in line.
