ESP control module

Hi everyone,

I have a 2003 A2 1.4 tdi recently i have had a couple of warning lights come on the dash, the abs light and a yellow triangle with an exclamation mark in it also when i drive and press the brake there is a large red exclamation mark in a red circle in the middle display, i have had a diagnostic done and it has some back with the following,

00493 esp sensor unit,

Firstly has anyone else encountered this problem and what can be done?

Audi has quoted me £800 ish to fit a new esp control unit after they looked at it, i am at a loss, can this unit be easily replaced and if so where can i get one from?

Hope you can help

Hi mate.

That code relates to the following:


00493 - ESP-Sensor Unit (G419)
00493 - ESP-Sensor Unit (G419): Implausible Signal
Possible Symptoms

* Malfunction Indicator Light (MIL) active

Possible Causes

* Steering Angle Sensor (G85) not properly learned
* Wiring/Connectors from Brake Electronics (J104) to ESP-Sensor Unit (G419) faulty
* ESP-Sensor Unit (G419) faulty

Possible Solutions

* Adapt Steering Angle Sensor (G85)
* Check Wiring/Connectors from Brake Electronics (J104) to ESP-Sensor Unit (G419)
o Check Measuring Value Blocks (MVB)
* Replace ESP-Sensor Unit (G419)

Special Notes

* In some Models the ESP-Sensor Unit (G419) contains several individual Sensors like for Rotation Rate and/or Transverse Acceleration.


00493 - ESP-Sensor Unit (G419): Defective

As you can see that code can be caused by various things. You need to find out from who ever scanned it as to whether it was the defective unit or implausible signal variety of the error code.

Cheers to you both, will try the fuse, i don't suppose anyone out there has the part number for the esp unit, need it to get a replacement and haven't got it off the car yet
 
It only needs replacing if you have got the defective message with the code. If its the other one then there are a variety of checks to be done:

Possible Causes

* Steering Angle Sensor (G85) not properly learned
* Wiring/Connectors from Brake Electronics (J104) to ESP-Sensor Unit (G419) faulty
* ESP-Sensor Unit (G419) faulty

Possible Solutions

* Adapt Steering Angle Sensor (G85)
* Check Wiring/Connectors from Brake Electronics (J104) to ESP-Sensor Unit (G419)
o Check Measuring Value Blocks (MVB)
* Replace ESP-Sensor Unit (G419)
