ASR - Anti slip regulator
It is located on each of the front wheel beside the rotor disc.
Solution (when ASR lights up on your cluster)
1. Try cleaning the sensor on each of the wheels.
2. Check disc pad and the sensor connected to it, make sure the disc pad is still thick enough for safe stopping and that the sensors are still in its right position.
3. Check that the harness (located behind the ASR sensors are not damaged or cut.
This are the possible cause of it to fail.
Unless the sensor is broken or the lines are cut, there is no need to change the harness as it will not help in resolving the problem, it will only make the parts supplier happy and would definitely cut thru your pocket for a needless expenses.
There is a pimp located on the left front wheel well and close to the rear part of the wheelwell, make sure the pump is in order, by testing it with a volt or amphere meter.
i hope this will help a lot of us who has the same problem.
Got this information by first hand, no guessing game I checked out the system thru a star diagnostic and thru the EPC of Benz and did the proceedures by my self with the aide of a pro.
