A week ago it had the first said message flashing up… with the off and turn on of the car he usually went wake up but now it does not help anymore.. according to öamtc it is the abs sensor at the front left (electrical error). Since then also the tempomat no longer works like t1 and t2 Even the automatic light does not switch the dipped light to position 0. The active sensor has been changed but the error is still there. At the plug approx. 10,5V on… . Öamtc exclude the magnet ring because otherwise the error would be erasable and only occurs again when driving. Did someone ever have the same error? I think next I will measure the voltage right and see if it is comparable “low”. Otherwise I am stunned Lg and thank you already Ps. Are the sensors sensitive to the installation?
