Audi fault code glitches

Order Reprints

Sporadic fault memory entry problems may be encountered in all Audis due to widened contacts (caused by using incorrect pins or incorrect methods for current flow tests). Either action may cause intermittent electrical connections, resulting in sporadic DTCs to be stored in various control modules. Verify that all pins and terminals are securely clipped into the connectors, that no pins are bent or deformed, and that proper crimping is achieved. Use only 0.63mm male pins (since the female terminals are designed for these pins, which are the only terminals found in the connectors for the control modules).

If a pin/terminal is deformed, improperly crimped or does not contact correctly, the contact must be replaced with the VAS 1978A repair kit.
