What sorts of clever things can we do with the ESP button?
Is there a ram location/variable for it in the ECU? How does it interact with torque intervention and ASR?

I had someone look into this for me and he stated that the ECU does not know the state of the ASR module. I wanted to use the button for enabling/disabing features but it doesn't seem possible.

Aren't ASR and ESP two completely different systems? They work similarly, but I only see ESP buttons on 01+ B5 and C5 cars, and I've only seen ASR on early FWD cars. I have almost no first hand experience in how the ASR in fwd Audis work, but I know that the ESP in my 01 A6 can directly limit engine torque output relative to steering angle, wheel speed, etc. It also shuts off cruise control when certain limits are exceeded. If APR can swap maps with the cruise control buttons, surely something can be done with the ESP button...
If the ESP button runs through the ABS, and not the ECU, could we set it to disable our ESP and ABS (like the old Quattros)? It snows where I live, and I hate my ABS, I also hate it when my car beeps to tell me I've pulled the fuse...

The ESP button is not connected to the ECU, but to the ESP/ASR controller.
The ECU gets periodic messages via CAN from the ESP system. In these messages
the requested torque limits are contained and the ECU can see if the ESP wants to
intervent. But there is no flag contained which shows wether ESP is disabled or enabled.
So not really an option to use the ESP button for map switching.
If you log all ESP messages on the CAN bus with ESP on and off, you can check this.

Best bet is to just fully disable asr and esp in the "brake controller" and recode for abs only via vcds "0004097" ASR FRONT MK60.
I had some issue with asr still active when disabled by the switch, asr and esp are still active in the ecu, limiting high rpm and torque
Would be pretty awesome to have map switching with the asr or esp button, Like the APR cruise stalk feature.

ASR is in the ABS controller. It uses the wheel speed sensors to detect wheel spin and applies the brakes to the wheel that is spinning at least 100rpms faster than the others. I read somewhere that leaving it enabled will get you about a half second faster time at the drag strip. |

That's a bunch of croc. At least the way it comes mapped from factory |

With this method does the ESP light stay lit on the dash all the time? |

No light will be functional on the dash and non operational switch, recoding brake controller will effectively disable asr and esp |

Still like the thought of map switching via asr or esp switch

Please make note of your original coding before making changes to the brake controller for abs only, incase you ever want to switch it back. my original coding was 0021505 and then recode for abs only to 0004097 |

I'm interested in doing this on my 01.5 S4 as I'm tired of always hitting the ESP button when I hop in the car. What vehicle did you recode yours on?

01 mkiv gti. aww motor. DL ecu. if you visit the rs wiki under abs controller, they would have the calculations to correctly recode your specific controller for abs only. Like I mentoned above my original coding with abs, asr and esp was 0021505, deducted the asr and esp drops it down to 0004097 abs only This was a simple solution for time being, maybe different methods on here, but I am still new to learning tuner pro |

As far as I know this CANNOT be done on ME7.1.x But if it is, I'd LOVE confirmation that it works. |
