How do i reset the abs and esp light on an Mercedes e270 chi from 2004

check and test abs system and or hubs for failure Finally Fix Mercedes class ESP ABS BAS FAULT LIGHT Malfunction

Brake light switch problem may cause the ESP / BAS lights to illuminate.

Common symptoms of a bad
Mercedes brake light switch.

• Car stuck in Park.
• ABS ESP ETS lights come on.
• Can not move the shifter from Park to Drive.
• Brakes Defective Warning on Instrument Cluster
• Car won't shift gears. Stuck in 2nd gear, limp mode.
• Brake lights don't work. (Brake light switch can still be defective even if the brake lights work. Checking the brake light operation is not a good test.)
• ESP, BAS, ABS lights turn on. Car won't shift properly. Stuck in gear.

TEST: To test your new brake light switch: Turn you car off to reset the ABS light. apply the parking brake. and start the car in neutral or park without using the brake. if the problem is the brake light switch... the light will only come on when you press the brake pedal.

If you replaced the brake light switch and the light is still on you should check a few other things such as:

• Fuses and Relays
• ABS pump
• ABS wheel speed sensor
• Brake Fluid Level
• Get an advanced scanner to read trouble codes.

NOTE: ** You may need a MBZ scan tool to reset the error code which was stored in the ECU because of the bad brake light switch.

The ESP system means the Electronic Stability Program. If the ESP lights on the dashboard permanently the ESP system is faulty.
You should access the ESP Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: brake pedal switch, front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP ECU, in other words reset the ESP system and turn off the warning lamp on dashboard.

Check & replace if necessary the brake pedal switch placed above pedals on the support.
If the problem still occurs you should access the ABS & ESP ECU (Electronic Control Unit) using diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC (Diagnostic Trouble Codes) memored.
Then you will be able to replace bad piece(s) and fix the problem by erasing all DTC stocked inside ABS & ESP ECU, and reset it.

MERCEDES BENZ DEALERSHIP HAS TO REPROGRAM THE ANTI LOCK BRAKE SYSTEM AND ELECTRONIC STABILITY CONTROL SYSTEM.IF YOU DISCONNECT BRAKE PAD WEAR SENSORS WHEN REPLACING BRAKE PADS. THE ABS BRAKES AND ESP SYSTEM HAS TO BE RESET TO TURN OFF ESP LIGHT.

The ESP light will come on whenever the abs light is on, this is due to the ESP system cant operate if the abs system is not working.The first thing you will have to do is scan the computer for codes. the computer will store a code whenever it sees a problem and then turn on the light to warn you theres a problem and then shuts down the abs system, there are many auto part stores that scan check engine lights for free as far as the abs system i am not sure you will have to check. the codes will tell you what part of the system has failed. for example there may be a code like C 1201 left front wheel speed sensor, this code will tell you theres a problem with the left frt sensor, it may be the sensor or the wiring or connector but with a little testing the problem can be repaired. the only thing is the esp and the abs are shut down, the car can still be driven you just wont have the abs. good luck and i hope this is helpful.

the stalk should have no interference with the abs or esp set up what i would look at doing is checking your abs sensors they can go all of a flash...goodluck

• you need a Brake safety switch replaced.This is located behind you brake pedal.it's a common problem. The warning lights will reset after a few engine starts.

I had the brake light switch replaced by a local dealer. Cost was $140 and it fixed the problem. Have driven the car for two weeks since and no lights and all systems normal.
