Tip & How-To about Mercedes-Benz E-Class
In the 1990's the ASR system was introduced into Mercedes Benz. Traction control was a great feature but now these systems are aging and giving people hard times with the "limp home mode".
First is a simple check. Sometimes the accelerator cable becomes bound or tight. As holding the gas pedal down from the hood while starting will initiate the ASR limp home mode condition back off the adjustment to put just a little slack in the cable. This will allow no tension at start up and allow light not to come on. Lubrication of the cable is a great idea at this age also.
There is also a speed sensor on the front drivers wheel behind the hub that should be removed and cleaned to provide accurate wheel speed and let the system operate correctly. Also in most MB's of thiese years there is another sensor in the rear end that reads rear axle speeds for proper traction control. This unit is better replaced than cleaned due to the high use and heat from exhaust and milage involved.
If you have been to push the gas pedal to start your car there are other issues involved than ASR and you should look into your ignition parts or fuel delivery system.
I hope my tip helps those with this problem.
