On my passat ESP warning is coming on. i have changed yaw rate sensor allready and ESP warning light is still coming on. what should i do? its Passat tdi 130, 2004. Thanx

The code needs to be read first.Sounds like the steering angle sensor needs to be reprogrammed with requires high end scan tool. Sometimes driving the car helps the ecu to relearn steering angle sensor.

Check & replace if necessary the brake pedal switch placed above pedals on the support.
If the problem still occurs you might access the ABS & ESP ECU (Electronic Control Unit) using diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC (Diagnostic Trouble Codes) memored.
Then you will be able to replace bad piece(s) and fix the problem by erasing all DTC stocked inside ABS ECU & reset it.

The ESP system means the Electronic Stability Program. If the ESP lights on the dashboard permanently the ESP system is faulty. You must access the ESP Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: brake pedal switch, front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP ECU, in other words reset the ESP system and turn off the warning lamp on dashboard.
I'm convinced that your brake pedal switch is faulty because the glow plug warning sign went ON after ESP warning light. Just replace the brake pedal switch, see if rear stop lamps light when press the brake pedal, and test the car on the road.
Good Luck!

This sometimes is triggered by the MAF(Mass Air Flow Sensor), try cleaning it with the highest percent isoproply alcohal first, do not touch the sensor with anything use a big bag to soak it into, or just replace the sensor.

As we tell everyone else who comes on here with warning lights: When there's a warning light on, that means a trouble code is stored in the computer. Don't ask us to guess what caused the light to go on when all you have to do is get the trouble codes read.

In your car Electronic Stability Program system included many different sensors (yaw-rate sensor, steering angel sensor, body acceleration sensor, some more) if ESP visit Workshop message appear on your instrument display It's very hard to say witch sensor could be the fault without right diagnose most common faults are either steering angel sensor or yaw-rate sensor might be some other sensors if you replace yaw-rate sensor it's need to be calibrate by diagnose computer, if replace steering angle sensor it's need to do right way otherwise when you tern steering wheel fully left or right it will brake at first time then you have to be replace another one so like to advise you to get right diagnose and repair buy Mercedes specialist if do some thing wrong it's be more cost to you if you get right place to do it only you have to pay once.

There's a level sensor plugged into the bottom of the coolant reservoir. Unplug it and clean the contacts with electrical contact cleaner. If that doesn't do the trick, replace the sensor.

Hi Amanda
I have come up against this problem a few times before.
If the ABS. light is NOT on, and its the ESP light only that is on...your problem may well be a faulty Yaw sensor. This unit is fitted to the floor panel under the rear seat...in the centre. Another problem (although not all that common) is a faulty ESP switch. You should have an OBD code reading done to make sure. If a new YAW sensor must be fitted, the car must be driven with a full steering lock in both directions (left and right) at a speed over 20 Km per hour after fitting. If this is not done the light will remain on, even though it will now drive ok.
As for the price of this unit...Here in Ireland it costs around 140 euro. Hopefully its cheaper where you are. So better to have the codes read first.
I hope this is of some help to you.
Good luck with it
John

The eps light is related to your brake light sensor. The emission light you will need to have the code read. Go to your local auto parts store and have it read.

the stalk should have no interference with the abs or esp set up what i would look at doing is checking your abs sensors they can go all of a flash...goodluck
