A4, 1.9, Diesel, 2003 - ABS/ESP lights on

[Geo]

ABS and ESP lights come on when you press the brake.

VCDS scan showed the following:

Address 03: ABS Brakes
Control Module Part Number: 8E0 614 517
Component and/or Version: ABS/ESP front 1729
Software Coding: 04155
Work Shop Code: WSC 06435
1 Fault Found:

01435 - Brake Pressure Sensor 1 (G201)
35-00 - -

Brake pedal switch has been replaced and operation checks out ok in measuring blocks.

Got the following readings from the pressure sensor in measuring blocks:

Pedal Depressed:
20:38:50 Group 005
2.5° Steering Angle Sensor (G85)
0.27°/s Rotation Rate
114.25 bar Brake Pressure
-0.38 m/s*2 Transverse Acceleration

Pedal Released:
20:38:58 Group 005
2.5° Steering Angle Sensor (G85)
-0.27°/s Rotation Rate
-0.65 bar Brake Pressure
-0.38 m/s*2 Transverse Acceleration

Ross-Tech wiki suggests brake bleeding and basic setting, then perhaps control module replacement.

Anyone come across this one before?

Try replacing the brake light switch (fit it correctly) then ersae the code
