| Hello,
I have a 1998 SLK230 (automatic). Few days ago I noticed that the ASR warning light came on (only the warning, not the Hazard triangle light). After lot of reading, I tested a few things.
After starting the engine the ASR is off. After a few minutes of driving ASR light comes on. If I manage to drive without braking (hand brake and luck...), the ASR wont come on.
And when I start using the brake, after a few brakes, the light comes on when "releasing" the brake.
I also tested this, without moving the car. After starting the car, keeping the hand break take the car our of P, and press the brake pedal a few times.
In a few tests, I noticed that the ASR comes on no matter if the gear is in P or D.
I didn't see any issues with the break light.
Now, .. I am thinking, that since the car is not moving, likely it is not the speed sensor. (Hall effect sensor).
Based no these tests, can we conclude that very likely it is the brake switch ?
How difficult is changing this switch? I have already opened up the plastic trims before (for chaning the bulbs behind cluster). Is the switch easily accessible near the pedal? any tools needed?
Thanks
