Summary
This article highlights Audi's strict requirements regarding one-time-use parts and fasteners as detailed in their official position statement and ElsaWeb/Erwin repair manuals. It emphasizes that worn, deformed, self-locking, or torque-to-yield (tightened with an additional angle) fasteners must always be replaced.
What to do on the job
Always replace self-locking nuts and bolts, fasteners tightened with an additional tightening angle, and any other one-time-use parts specified in the ElsaWeb/Erwin repair manuals.
How to use it
Use this document and the referenced Audi position statement to justify the replacement and billing of one-time-use fasteners, self-locking nuts, and torque-to-yield bolts on estimates and supplements. Point to the OEM requirement that these parts are unreliable and prone to failure if reused.
