What is ASR VW Golf?
ASR or ESP (electronic stabilization program), as it is now referred to, is the first part of traction control. ASR uses the anti-lock brake sensors to determine if one driving wheel is spinning faster than another due to a loss of traction, over useage of the throttle, too much power for the road conditions, etc.
What causes ASR light to come on?
What does ASR switch mean?
The function of ASR (Anti-Slip Regulation) is to prevent slippage of the drive wheels and improve traction during acceleration. The ASR electronic control unit: optimizes vehicle stability, prevents slippage of the wheels at all times. and reduces wear on the tyres.
What is the ASR in Mercedes?
The ASR monitors the Steering angle sensor & Accelerator position sensor. Wheel speed is continuously monitored by the ASR module. It controls the braking of the rear wheels when it has noticed a slipping of the wheels until the slip has been corrected. It does not plug into the transmission.

What should I do if my Bas/ASR lights are not working?
If you replaced the brake light switch and are still having problems with the BAS/ASR lights, the next thing to check would be the ABS wheel speed sensors. They are installed on two (diagonal) or all four wheel knuckles and measure wheel revolutions.
