Knock Sensor: Technical Service Bulletins
Knock Sensor - Torque Specification Revised
Group: 28
Number: 93-02
Date: March 15, 1993
SUBJECT:
Knock Sensor Torque
MODEL(s):
90 w/Engine Code AAH
From 1993 m.y.
The knock sensor torque as specified on page 28-24 of the Audi 90 (B4) Repair Manual is incorrect.
The knock sensor torque on pages 01-49 and 01-54 of Repair Group 01 has been incorrectly converted into foot pounds.
The correct torque for all of these applications is: 20 Nm (15 ft lb)
CAUTION
The specified tightening torque is critical to the proper function of the knock sensors.
The Repair Manual will be corrected to reflect this change in the next update.
