Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

Legend of Abbreviations. ABS Antilock brake system.TCS Traction control system, TCM Transmission control module, SRS Supplemental restraint system, BCM Body control module

Break lights


The problem is that you pressed the pedal to the max when you installed the new switch. The switch is improperly adjusted. You should just have to loosen the mounting bolts on the switch, have someone watch the lights and adjust the switch so that the lights come on when the pedal is depressed about a quarter inch. That should fix the problem because your ABS and ESP systems monitor the brake light switch and when it comes on so if it doesn't come on or stays on it messes up both of those systems.

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.

I'm convinced that your brake pedal switch is faulty because the glow plug warning sign went ON after ESP warning light. Just replace the brake pedal switch, see if rear stop lamps light when press the brake pedal, and test the car on the road.
Good Luck!
