2001 mercedes slk 200 esp/bas light comes on just after pulling off but car runs normal.What can be wrong,bas or esp

SOURCE: Warning Light on Mercedes ML270

Hi,

To my understanding:
BAS ESP - Electronic Stability Program (keeps you moving in the direction you intended the vehicle to go); probably a faulty brake switch or a bad brake sensor. You may want to reference this forum for additional insights;
ETS - Electronic Traction System (keeps you moving); would require an appropriate code reader to diagnose and pinpoint problem.Surprisingly, there has been some reports of defective brake pedal switch that activates this warning. You may lilkewise want to reference this forum for additional insights.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Hi, these systems are all linked together. Most commonly, one of the wheel speed sensors is not reading or is reading incorrectly. This can also occur on slippery surfaces where one or more wheel slides enough to cause the sensor to drop the signal, but not enough to meet criteria for an abs or esp episode. If the light comes back every time you turn on the ignition, there is a deeper problem.
The system has detected a fault in the electronic stability program - brake assist system. You have an electrical connection at the rear wheels secured to the inside of the brake area and are viewable from under the vehicle. It is a small wire harness running to each wheel. Grab the connector and wiggle it around, and make sure they are tight. Due to the connector being mounted low to the ground, sometimes they become dirty or corroded, not making contact. Do this on both sides and see if the lights turn off.

If the light does not turn off, you have to replace dynamics sensor, which is mounted UNDERNEATH the center console in the car. There is a "lost communication to dynamics sensor" and "low voltage to dynamics sensor supply"..
