    esp light coming up at throttle let off

    hi all,
    have a small problem, not impacting anything, but would be great if you could suggest any ideas to fix that.
    the proble is the esp sign lights up eventually from time to time on the dash. it mostly happens when after acceleration (regardless hard or not) i let throttle off. it happens rearly, might not appear for weeks. it does nbot blink like when abs starts to work, just the car make a Ding! sould and the esp sign light up until i restart the car.
    i am pretty sure it is about the tune, but i cannot figure out what it is. it started to appear after i got supercharged and has been happening since then. again - not impact on anything, lust the light.
    if any ideas - thank you in advace ))photo_2025-07-08_11-18-08.jpg

    i have the same issue, its happening most on decel , in manual mode it will happens every time that you decel on a gear for a few seconds.
    the dtc will be in the abs module C1082 brake booster vacuum sensor.
    i tried and changed the sensor including the check valve, checked that everything is good no vacuum leaks at any of the lines, and the brake booster hold pressure as it should, did ABS module initialization, nothing helped it still doing it.
