Mercedes-Benz ML320 Brake Light Switch Failure May Cause ESP/BAS Warning Lights

(77 reports)

The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern. A recall on certain 2000-2002 models have been recalled for a related issue - for more information please click here»

The esp/bas lights turned on and then the car would not like to move as if something is holding it back or locking it up.Going slowly it started running well as if nothing happened. -
My break light switch has failed twice. Once causing the break lights to stay on continually and BAS/ESP light to illuminate. And one causing the break light to fail and and the gear shifter to lock [safety feature:(] -

Brake Lights don't work and ESP/BAS warning lights on. I will replace the Brake Pedal Switch next week and will report back if the problem is fixed. I replaced the Brake Pedal Switch last week and my problem is solved - Thanks a million to the people in this forum. -
Every year I have to change the break light switch -
The stealership wanted to replace one sensor or another, after charging me $200 to diagnose the issue. I decided not to do it. Turning off the car and turning it back on typically turns the light off. -
Lights activated and cruise control would not engage. Replaced brake light switch and everything works fine. total cost around 15.00 DIY -

ESP/BAS warning wont go away. I read is a electronic module which solder needs rectification. -

hAVE TO REPLACE OFTEN DUE SWITCH INTERNAL CONTACTS STUCKS. sTOP LIGHTS ALWAYS ON -
ESP/APS Brake lights on. Car Accelerated on its own. Brake Break lights no longer work. I was told it was the ESP Stop lamp switch -
I have had 3 switches fail after a 100K each time. The main switch console for all the power windows was made in Mexico, at the price Mercedes would normally pay for just one switch, so you get what you paid for, even the Mercedes mechanics know the switch console is a piece of junk. I have 3 solutions not including changing cars, leaving the window down or up, but in a MacGyver way of remedying the issue for ever. 1. I've broken the switch cap and leaving part of the knob, I attached a small pair of vice grips which although looked awkward did the job of providing additional movement for the switch to make contact where over time the contacts have burnished, or covered with electrode dust that you can't get to to clean. 2. I've whittled on a ink pen casing to match a snug fit over the knob, and it still provides leverage to use, although I seem to loose the lever between the seats. 3. The best way to eliminate the issue and make the car still resemble the luxury we thought we were getting is to by-pass the switch and install a 3 way toggle you can get down at the parts store. If you wish to install as many toggles as there are in the console, just let the module be lowered into the well below the place it fits and install the toggle switches through the same holes in the paneling and use some nice washers to seal them up tight. Now just do some simple wiring into the switch console and attached with cover plates. My SUV is going on 450K, and with each new adjustment it improves in value, even though it may not be pure Mercedes, they knew it when they built it to a price point rather than building the car and figuring out the price.

ESP/BAS lights came on and need to use BIc pen to release shifter from park position. I have also noticed a issue with the cruise control not disengauging when I apply the brakes. I never had this issue until the brake switch failure. -
I have already had to have the brake switch changed twice and now it seems the pump is sticking but the same lights are coming on. -
ESP/BAS is on since I had some work done on my 2002 ML320.The battery had to be disconnected at the time,but now the light won't go out.Why? -
brake light malfunction the day we bought it in 2006 - service engine light going off and on since 2006 and ESP/BAS light - Shuddering engine car takes off from a complete stop - -
There is a chime bell that remains on when in gear. The brake light is also stuck on as well as another light. Cannot remember. Will ask husband. -
Please note: Mercedes has now admitted fault that brake switch fault was overriding ability to allow breaks to function and are recalling approx 134,000 units - might want to check into it. -
