      fault C 13 14 means solenoid supply voltage meaning that the solenoid valves in the hydraulic unit are not getting the right voltage. infact i measured and found that the esp control unit is producing 3.02 volts instead of the required 11 to 14 volts.i took my esp unit and put it in a different car and it produced the required voltage.i ruled out that the esp control unit is faulty.my big question is, what is making my control unit produce such a low voltage yet when I put in another vehicle it produces the required voltage?? If any of you is on whatssup I can send him the pictures. no - used star diagnostics

    Could a bad front bearing cause an ABS/ESP MESSAGE
    I took the car to the dealer recently and they change the conductor plate and the sensor inside the transmission. The same day the car came out of the shop an ABS/ESP message came on and did not went off. The dealer is telling me is because a bad front bearing. ...

      Several possibilities; dirty or loose connection at wheel sensor, a fault with the ABS module, ABS and traction control pick up their information from the tone rings on the front wheels. A bent ring or bad sensor will set both errors.
      Many hub assemblies have the ABS sensor built into the hub. If this is the case with your hub, to fix this issue and restore your ABS, you will need a new hub assembly.

      Check these various on-line vendors; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, to list only a few. For example, they (RockAuto) list the front ABS sensor from around $74.00 each, and the front wheel bearings (outer) from $2.70 each,and the inner bearings from $11.70 each for your vehicle.

      the brake pads or discs get wet when you get your car washed. this might be the cause. just pump the brakes to dry them, it should just work fine afterwards. is this the only time that the brakes fail? if there are other instances get the brakes/lines checked, you might have a leak or air in the brake lines.

    Mercedes-Benz E class - third brake lamp
    Hi I have got a Mercedes-Benz E class 200 CDi (W211, 2004) and I observed third brake lamp is not functioning. What I am supposed to do now. Could you please tell me the third brake lamp's fuse location? I think first I should check this one. Thanks a lot! ...

      Check these possibilities; faulty light bulb, faulty wiring or connection for the brake light. There is no separate fuse to check for the single light - same circuit as the rear stop lamps.

    My brake pedal soft after I had the brake fluid changed.
    I had the brake fluid replaced in this car, per Mercedes recommendations, and the brake pedal became soft. I thought there might be air in the line, but the garage says no. I have to push the brake pedal down a considerable distance before the brake engages, and ...

    Brake Line leaking!! How many brake lines does Benz 300 have? Left or Right? Front or Rear?
    I paid to fix the 'left' line leakage barely 6 months ago, now, I am told that the right brake line leaks compromised by the breakage of the rear spring-coil!??

      Possible air in brake line. Try Bleeding. Another possibility is the anti lock metering valve.

      Air in the system doesn't make vibration it can cause a spongy brake pedal, double check the tire pressure, make sure all lug nuts are tight and torque properly otherwise its uneven or if you can lift both front tires and wiggle them up and down and side to side make sure they are firm and tight, this method is just to make sure that your wheel bearing is installed properly and this method is to make sure that your inner and outer tie rod is firm and no play

    I replaced master brake cylinder, calipers,rotors brake lines.bleed master cylinder and calipers and still no brakes
    what step if any im missing,how to check brake booster.

      First off check that the vacuum hose is connected to the brake booster. Second, ensure the check valve that connects the brake booster to the hose is oriented correctly. It's a one way valve. If you pull it out, the side that you try to blow through that doesn't allow air through is the side the vacuum hose connects to. Similarly, if you apply suction to that same side, it is the side that connects to the vacuum hose. The other side connects to the booster.

      If all of the above is well, your next step is to listen for any hissing sound, particularly inside the vehicle cabin. With the car running, step on the brake. If the pedal is stiff and you can hear a hissing-suction sound, then the brake booster diaphragm has a tear in it and needs to be replaced.

      Ensure that all air in the brake system has been bled out. Keep reservoir topped off during any bleeding process. The most basic bleeding process begins with the rear right, then rear left, then front right, then the front left brakes. It may vary on your vehicle, so make sure you look that up.

      Ensure the seal that connects the reservoir to the master cylinder is intact and not leaking. Likewise, ensure the seal for the reservoir cap is also intact. Check all brake lines, caliper and wheel cylinder bleed screws, as well as caliper and wheel cylinder pistons for any dripping fluid. For wheel cylinders, it is normal to have a small amount of brake fluid on the end near the pistons--it is ok for it to be slightly damp with brake fluid, but any dripping is not ok.

      If utilizing drum brakes, ensure the adjustment is correct. If the adjustment is too low, the shoes will not contact the drum, and your brake pedal will drop to the floor.

    How much is a tune up kit?
    I need a tune up.

      Impossible to quote until a mechanic looks and sees what is needed. They do not sell "tune up kits" anymore. Mercedes Benz is not like other ballpark estimates on other cars.
