Your Bas & Esp Light is on due to a failing or already failed Bas sensor & Esp Sensor, You can either do it yourself which can be very tricky if you are not confident with automobile repairs. The dealer should be able to do this at a reasonable price as it should take around an hour to do the repairs. If the problem keeps arising there could be a problem elsewhere that is connected to the same area & is shorting out.
I hope this helps.

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"..
