ESP / BAS / ABS warning lights come on. Brake lights work intermittently.
Shop replace brake light switch and relay. Checked all bulbs / connections. Fixed the problem for 10 miles, then the same issue came back.
Returned to shop. They had the car for 2 days. No warning lights came on and the brake lights worked fine. 10 miles from the shop, the warning lights came on again and brake lights didn't work.
I replaced the brake light switch as second time, but that did not make any difference. Problem still comes and goes.
Going back to shop again.
Turn on ignition, step on break and get lamp defective, BAS, ESP, ABS malfunction messages.
brake lights are now on all the time
Mercedes-Benz E320 : Brake Light Switch Failure May Cause ESP/BAS Warning Lights
Every year or so ,without fail I need to replace to brake light switch. The Bas/Esp light goes on and will want to lock out the transmission shifter. I have owned my car for 7 years and have replaced the switch 6 times. It is not a difficult DIY repair and takes about 20 minutes to complete. The switch is $25 and the dealer will charge you about $150 for labor to install it.
abs and esp and bas comes on and stays on
Brake light indicator. replaced switch worked ok for a few days.. i have noticed that after warming up the car, then letting it cool and problem disappears for the rest of that day them, next am, whammo! same problem this feels like groundhog day! ESP and BAS light warnings accompany this odd phenom! Makes me want to brn the car!!
warning scared the crap out of me. 14 dollar part.
I have had brake light problems due to the actual bulb receptical being loose. I can wiggle it and it comes back on. Also the ESP/BAS warning lights come on then after a while they go off. I have noticed it usually happens when it has been raining and I drive on wet roads. The E320 doesn't like water at all. Especially in the gear shift column right below the cup holder (the stupidest place to put one). Have had to replace that also.
The light switch failed and the BAS, ESP and ABS lights came on.
The good news is the parts from the dealer only cost $30. and the instruction are included.
The total fix time is about 1 hour.
Warning: Check Lamps. Fix: Replace bulb.
