Question about Cars & Trucks
Brake,abs, esp lights on on dask
Your car has a fault in the system that senses wheel speed and changes the way the car automatically responds to slippery road conditions. Often, successful troubleshooting of these faults will require the use of a special scanner; however, there are a couple of failure modes that a backyard mechanic can discover and correct.
If your ABS AND your brake light (on the instrument panel) are both on, it is likely your basic brake operation has a fault. In this case, please refer first to the tip on Brake Light Indicator.
First, let's understand how these systems work. The car/truck must have a sensor at each wheel to know for sure if any wheels are slipping. The usual method is to use a tone ring and sensor as shown below.
The signal from each of the 4 sensors is evaluated by the ABS system, which, if the brakes are applied, will essentially pump the brakes for you to prevent skidding. If the brakes are not applied but you have traction control, the traction control system will limit the differential behavior of the drive wheels to help you get traction. If you don't have traction control, the ABS system may alert you to wheel slippage with a "low trac" light. The logic and electronics associated with the reactive systems is different on different models, and that is why troubleshooting those parts of the system requires special scanners and training.
OK, so what can you do about getting those lights off without paying a specialist big bucks?
You can inspect the wheels for damaged tone rings, broken sensor wires or connectors, and misaligned sensors. The tone ring is usually visible at the end of the CV boot on a drive axle or behind the rotor on a non-drive wheel. For wheels with drum brakes, the tone ring may be inside the drum.
Spin the wheel looking closely at the tone ring for any missing or chipped teeth or a break in the ring. Check the sensor alignment to the tone ring and also the distance. If you can find the specs on the air gap, measure and adjust as necessary. If you can find specs for the sensor, check it with an ohmmeter for shorts and opens. There are a few more details on sensor diagnostics at the following page:http://www.brakeandfrontend.com/diagnosing-wheel-speed-sensors/.Check the connectors and trace the wires all the way to the ABS module to inspect for damage. Due to the variety of systems and conditions, I'm not going to try to cover repair procedures.

you'll have to have it diagnosed at a repair shop to pinpoint the source. sorry, but thats how they make them. you could buy your own but it'll cost about 200$

When there's something wrong with the brake pressure that handbrake warning light comes on.
The ESP warning light could be caused by a lot of things, but most likely it's a dirty fuel filter. Don't take my word for it though, just go to the VW dealer and have it read the faultcodes from the ECU, which should point you/them in the right direction.
Alternatively, when you have the right equipment (= VAGCOM + cable) and knowledge, you or a friend yould diagnose the ECU yourself.
From the sounds of it, you'll need a small service (air filter and oil filter change, etc.) anyways. Don't forget to reset the ECU (or dis- and reconnect the battery) afterwards to erase the faultcode from memory (when there's still something wrong, it'll return soon enough).
You might get lucky with a small service :)

SOURCE: 2008 wrangler. abs, esp and
Check first the third eye brake light. does it work? okay the problem reside in a ABS sensor make sure it is hook up or if you recently did a brake job it didnt get contaminated. When the ABS signal is interfered with ESP,Traction is disabled. One or some of the wheel speed sensor is disconnected or is being interfered with. This is common for a recent brake job if any occured
