I have a 2007 s550 Mercedes I was trying to find out are wheel speed sensors hard to change

Could it be, your vehicle has Psychic intuition? Just kidding... :-)

Well, actually...it's not far from it !!!

ESP was co-developed between Daimler-Benz & Bosch, and was later adopted by Mercedes (across their range) from 1999.

As you know, most vehicles now have ABS braking...and some now have a form of Traction control.

Well, ESP exceeds the safety boundaries:

It's an intuitive system, connected to your vehicle's ABS, steering, dampers and Drive-train management.

ESP has saved countless lives since its implementation by reducing the risk of skidding on cornering and by maintaining the vehicle’s directional stability – even in critical conditions.

How exactly does it work?

1) This is achieved by selectively braking individual wheels, thus counteracting the tendency to skid in critical handling situations and allowing the driver to maintain control of the vehicle.

2) Oversteer is corrected by applying brake to the front outer wheel, understeer by applying brake to the rear inner wheel. Engine power can also be limited in some applications

3) The system can measure steering angles, lateral forces, and can compensate the damper ride height (optional).

Hope this helps....

sorry to tell you this but it sounds like the wheel bearing was put in backwards on one or both sides. the front wheel bearings have a black speed ring built in and that is what your speed sensor reads off. - this is common as the front bearings will install either way- hope this helps

Hi,

Do you have another key?

If yes, try with another key.

If the same problem persists with the new key, its unlikely to be a key issue. The starter system is fairly complex & needs diagnosing on a diagnostic tool such as Mercedes STAR diagnosis.

The EIS (Electronic Ignition Switch) reads the key information & sends a signal to the engine ECU to start (assuming it recognizes the correct key), the ECU then sends a signal to the starter to start the engine. The problem could be anywhere in between these components.

The EIS is a fairly common part for failure but this needs to be checked for fault codes & actual value readings to check the status of the switch.

I would take it back to the dealer for them to investigate as soon as possible as there is a chance it could fail completely leaving you in a stranded situation.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

only dealer can reset or a regular auto shop that has a code reader.

one box is to the right of the glove box behind a false panel and the other is behind a panel located behind the armrest in the middle of the back seat.
