Steady BAS/ESP light ON
do not see the switch on the brake pedal,only see the switch on the emergency brake.
esp light is on
2 brake lights stay on one won't come on.
esp, abs error messages. Following others, just had brake light switch repaired. so far, no error messages.
bas/esp kept coming on intermittently. replaced the brake light switch which should have resolved problem but it hasn't. Dealer has been trying to figure out why this hasnt worked for the last 4 months. Dealer now suggesting that the related control module unit is the problem. They have replaced it several times with no resolution.
