Technical Service Bulletin Technical Background The insulation for the ABS wheel speed sensor is damaged in production. Over time, this can lead to corrosion on the wires and restricted functions with the ABS control module. Only the wires in the left bulkhead grommet (Figure 1) are affected. Figure 1. Left front fender is removed to show the left bulkhead grommet Production Solution Improved installation procedure at the factory. Service There are two different types of service actions based on the two types of DTC entries that can be found in the system. For vehicles with the DTC description “Brake Control Module - No signal/communication” present in several control units, proceed as follows: 1. Perform a voltage drop measurement on terminal 30 - supply for ABS control unit - under load (as described below). For the pin assignment, see Elsa wiring diagram. Proposed voltage drop measurement (using an A4 as an example): • Verify the fuse is good. • Apply a load (1.7 A = 21 W) on pin 7 (T38a) to ground • Set the digital multi-meter to DC Volts (Direct current voltage) • Connect the black multi-meter measuring tip to pin 7 (T38a) and connect the red measuring tip to fuse SC6 while keeping the fuse in the socket. © 2013 Audi of America, Inc.

Technical Service Bulletin • If the voltage drops (over 0.3 V), the wiring loom around the grommet must be checked (Figure 2) Figure 2. Affected area of the left front wiring loom behind the fender Tip: For better access to all sections of the wiring loom, the wheel arch liner and the windscreen washing reservoir must be removed. 2. If damage is found, please contact the Technical Assistance Center (TAC) and take a photo of the damage: • Measure the distance from the grommet front side (Figure 3, point 1) to the point of damage point (Figure 3, point 2). Include this measured distance in the TACS contact. Figure 3. Measuring point of damage in relation to the end of the grommet © 2013 Audi of America, Inc. Page 3 of 6 All rights reserved.

Technical Service Bulletin • Take a photo, using camera flash, of the grommet and original harness position from the passenger compartment (Figure 4). Please attach the photo to the TACS contact. Figure 4. Grommet position photo, taken from inside the passenger compartment. 3. Repair the damaged cable in the wiring loom using the VAS1978B wiring harness repair kit. 4. Remove the sections of the individual cable where the copper wires are black or corroded. 5. Pull back the insulation for the complete wiring loom, for a distance of about 40 cm from the grommet towards the front of the vehicle, and inspect for additional damage or corrosion. For vehicles with the DTC description “ABS Wheel Speed Sensor - Incorrect signal or Electrical fault in circuit” present in multiple control units, proceed as follows. 1. Perform the same measurements as above using the correct pin/fuse location listed in Elsa for the affected ABS wheel speed sensor. 2. Take a photo of the grommet position from the inside of the vehicle and attach it to the TACS contact. 3. Repair any damage found and ensure the black or corroded wires are removed. © 2013 Audi of America, Inc. Page 4 of 6 All rights reserved.
