All warranty claims submitted for payment must be in accordance with the Audi Warranty Policies and Procedures
Manual. Claims are subject to review or audit by Audi Warranty.
Please note the information on predecessors and items that are included and excluded in the repair operations as
well as any associated tasks.
Try to reproduce the customer complaint (based on the description/cause of the issue), so that it can be clearly
assigned to this TSB. The following repair must only be carried out if all the criteria (model/type, chassis number,
engine/motor, gearbox code, PR number(s), part number, software version, code, etc.) apply exactly. Otherwise, this
solution will not eliminate the problem and repeat repairs may be necessary. In such a case, the warranty claim may
be rejected, and the cost of the parts may be charged back.
