Default VCDS EPB Control Module Error

Dear Forum,

I had a yellow park brake warning light appear on the dashboard but the EPB continued to work normally.

I then had the battery go flat and in the recharging process, I attempted to start the car before the battery had enough current. This caused all the dashboard to go erratic but when the battery was ready, I started normally and even the yellow park brake warning light disappeared.

Then on a freeway run, the yellow warning light and a flashing red warning light appeared. After parking and applying the park brake, the rear wheels locked up.

I freed this and didn't use the park brake again until I got VCDS. I did an Auto-Scan and have the following "Defective" fault.

Address 53: Parking Brake Labels: 4F0-910-801.clb
Part No SW: 4F0 910 801 HW: 4F0 907 801
Component: EPB C43HC002 H03 0020
Revision: C43HC002
Coding: 0000321
Shop #: WSC 02334 785 00200
VCID: DDBB07AD042A2F1

1 Fault Found:
16347 - Control Module - EEPROM Error
014 - Defective - MIL ON
Freeze Frame:
Fault Status: 11111110
Fault Priority: 4
Fault Frequency: 2
Mileage: 83848 km
Time Indication: 0
Date: 2013.06.07
Time: 18:09:30

Freeze Frame:
Voltage: 13.04 V
Count: 187


On Ross-Tech's site, the error code suggests either "Update firmware" or "Replace Control Module".

My question is, how do you update the firmware on this control module and has anyone successfully fixed the same error without just replacing the Parking Brake control module.

Thanks in advance.

A firmware update needs to be done by a dealer tool that has connection to the factory resources. There are some "Official" flashing tools that can be bought in the aftermarket and require the user to use the Audi web site to down load the flash. They are referred to a as J2534 pass-through tool. If you can find someone who has one, you may be able to do this yourself. You can read about the program VW/Audi has on this web page: http://nastf.org/i4a/pages/index.cfm?pageid=3670

Note: I am not certain that the pass through flashes support all modules. You may still end up needing a dealer tool to do this. Some of the documentation seems to indicate that VW/Audi only allows flashes for emissions related systems.

Thank you bearthebruce,

So it is really only a replacement of the control module that may fix this error it looks like.

I did read that VW's can be reset by clearing the error code and running an auto-scan again. I did this as a possible fix but my Audi A6 3.0 TDI wouldn't clear the "Defective" error.

However, the parking brake still works with the yellow park brake warning signal on the dashboard. Also, running the function test in basic settings of the Parking Brake section of VCDS functions completely without fault.

Is there anything I should look at before replacing the EPB control module.

Thanks again for any feedback.
