today my car is telling me that brake wear, esp display malfuction and abs light came on. wanted to know if anybody has had this happen to them at the same time.if so what did u do to fix the problem.

i knw i have to change the pads and replace the brake sensors.

but what bout the esp and abs nonsense.

Why would you let your brakes wear to the point the car has to tell you?

bignaldo

thats the thing my brakes didnt even squeek or feel funny i started the car and i got hit al this at once so i shut off the car and started again and nothing went to work and when i left work it all showed up again but it wont shut off my rotors look good the brakes work fine had know reason to doubt u know

Very likely 2 separate issues with the car - one of the problem is brake pads are worn and needs to be replaced and the other problem is possibly caused by one of the wheel speed spensors (also called as ABS sensors) has gone bad.

For the first problem, replace pads, you will be good to go.
For the second problem, you will need to diagnose further to identify which (out of the four) wheel speed sensor is causing the light to come on. You will need to replace that sensor to resolve the problem.

how do i find out what speed sensor is bad

Xhale707

PShh... The wear sensor is BS... When mine went off i took my wheels off and still had over 20% left on them.. I went another 5k miles on them before i replaced them all.. Not smart but had to

Thats odd that your other sensors went off..

dynomite05

Did you drive that whole time with it on? To the OP it's probably best that you take it to a shop and get it checked out.

Xhale707

Yup i drove 5k miles with the brake wear sensor on.. Replaced all pads replaced both sensors myself and it went away. No issues no probs

bignaldo

well the pads im replacing tomorrow but the only thing bothering me is the sensor prob with the abs and he esp

Just for the hell of it turn your steering wheel all the way to the left and all the way to the right.. Do this 5 times..

bignaldo

why

Xhale707

When the Mercedes tech came out to my house to do a battery change.. I had ABS and ESP error as well.. But he said turning the steering wheel resets some sensor.. The steering angle sensor maybe but it was just a thought..

Few questions:
Did any other errors turn on?
Did did your car lose the ability to shift gears?
Did this problem happen after your lights turned on?
Do the errors reset after restarting?

Do you happen to have any electrical aftermarket equipment installed near your ECM? Maybe a HID kit or something? I know a ballast near the ECM can cause the same problems as "limp-mode" and even throw an additional 6 other errors.

Do the pads & while the wheels are off get them to clean the ABS sensors. Take it from there.

bignaldo

i did install hid

bignaldo

i mounted the one ballast on the face of the esp box under the hood on the drivers side. i just relocated it know im gonna plug the obd 2 and run some test maybe reset the computerhopefully it works i hope didnt fry anythng

bignaldo

and yes i cannot shift gears what do i do

dirtdiggler

start the car and turn off the ESP and report back..

bignaldo

i cant turn off the esp the button wont let me do anything so i am going to my cousin shop to do some work i will report back asap

take the ballast off the esp box. Its damaging it. You never want to mount an HID ballast on or to close to any other microelectronic components. I don't think there is enough shielding on an hid ballast to block all the electromagnetics being created so it's damaging your esp unit.

1. Change pads.

2. Holy allgetout, man! Never mount the ballast on anything electrical on your car! The ballast gives off waves that damage the unit, put simply. ESP failure due to ballast mounting too close has happened to a few around here.. mounting it directly on the unit is asking for trouble. I would move the ballast to as far as possible from anything electrical, and I know you can mount them on the wheel wells, as I did the same. There are even some tabs that were conveniently on the wheel well that helped keep the ballasts further secured.

If the codes don't go away, I would unplug the battery and reconnect in 5 minutes. Your car will be uncalibrated when you reconnect the battery, so recalibrate your windows and sunroof, and your steering sensor will be off. So, as mentioned above, turn your wheel lock to lock several times and restart your car. Codes should be gone for the esp/abs failure, but if they still persist, you may have put damage to the unit.

Good luck!

bignaldo

problem solved thank u guys for all the help

Xhale707

well tell us how it was solved and not just saying it was

nrg_mike

Moving the ballast should have been what solved the problem.

good to hear. and as for your brakes, if your are getting a message on your dash, don't forget to buy a new sensor. I always run my pads until my sensor tells me it needs to be replaced. You got plenty of pad left when the sensor is hit. It gives you a fairly early warning.
