MY Q IS :

There's something you can try, turn the car on and turn your steering wheel all the way to the right and then all the way to the left, turn off the car and restart it. See if you still have the error.

Well Player ,,i have try all this :

1- Removing the battery.for more than 10 min and plug it back.
2- Resetting all the fuses.
3- Visual check of the ESP & ABS front R,L SENSORS,For damage,
dirt,and re-plug them both.
4- Also turning the steering all the way R,L and turn off the car and restart it.

Note : after disconnecting the RIGHT and LEFT FRONT SPEED SENSOR,and reconnect them back ,start the car,the ESP/ABS Error goes off,as soon as the car accelerate to 20 or 30 km/h, the msg ESP and ABS DEFFICTIVE shows again in the cluster,and the yellow Triangle comes on n off , and a brakes automatically applied ,causes the car to stop,>>!!!!!!

also the CRUISE CONTROL not working,it shows this msg :
Speed tronic / Cruise control visit workshop

whaaaaaaat is allllllll theeeeeeese !!!

Are the front tires the same size as the rear tires and or did you only change the two front tires. In addition are the front tires inflated to the same pressure as the rear.

Regarding the steering fault----just go rack to rack with the steering wheel

PS: You do not change speed sensors unless they themselves are faulty

PSS: That is correct if you disconnected the battery and did not clear the fault, it will take a drive cycle to clear(move the fault out of current status)

If you disconnected the battery the ESP will throw a warning. It will clear after you drive it a bit. I dont' think you have anything bad. IF you did the lock to lock on the steering wheel then drive it a day or so and see if the normal cycle clears.

Agreed on the tire/wheel change make sure that rolling diameter is identical or nearly identical. It might be an installation error as well but you seemed to have ruled that out.

As for the front tire and rear tire pressures, go only with the pressures listed on the card for the car itself. I think on my 07 it is 33PSI for the front and 35PSI for the rear, could be wrong but always do it within MB specs not tires specs.

I am not one for throwing parts at a problem, especially for something as electronically complicated as an MB. However, I have had my steering angle sensor replaced, and then some time later have had the warning come on again. The second time, it was the brake stop switch-that is a cheap and easy fix, a very common problem, and might be worth throwing a few bucks at.

Just a thought.

wel,,,,,i just checked ur posts,,,,

1-my tires all are same R16/245/45
2-Corrected the tires pressure,disc/connect the battery again,still the ESP/ABS showwws
3-Moving the steering from lock to lock ,,,and went for drive,,,stil the ESP/ABS showwws

but,,,how to make sure that rolling diameter is identical or nearly identical ???

AMGAffalterbach

If your tires and wheels are the same you will have identical rolling diameter. The danger is when you have a staggered setup on a rear-wheel drive car. So I think you're fine there. How off were your tire pressures?

wel,finally today the problem is solved,,the MB dealer find out the abs speed sensor,is damaged,so they replace it both,and the problem is gone,No more ABS/ESP warning !!!


thank u all,,,,
