•
•

Information:

Outer tail lights (left and right)
Tail light in rear lid

Production-related visual defects can occur on the tail lights over the service life of the vehicle.
These may be slight cracks at the edges ("Shining line") or significant cracks.
Information
Lighting components are not designed to be completely leak-tight due to the open, spray water-proof
ventilation system (required for pressure compensation purposes).
A build-up of moisture on lighting components is not caused by a defect and does not reduce the light
output in any way. For this reason, if lighting components fog up, this is not a safety-relevant complaint
and does not necessarily justify replacement of the affected lighting components.
Approval for replacing lighting components and the relevant invoicing must be evaluated based on the
following examples.
This Technical Information is designed to help you to assess the extent of fogging and explain the
situation to the customer.
It is not a blanket approval for replacing components. The decision to replace a component must
be made based on the information provided in this document. If you are not sure in some cases, we
recommend that you get in touch with a contact person with higher authority.

•

When replacing components that will be settled under warranty or goodwill, clear documentation is absolutely essential and must be attached to the job.

 The documentation will be checked if required during the PSA (Porsche Service Analysis).
 Furthermore, we reserve the right to reject warranty claims if the instructions relating to documentation are not observed.
Measure:

Assess the extent of the visual defects on the tail lights based on the following criteria. If there are
significant visual defects, replace the affected tail light.
Information
•

Due to production errors and the resultant supply bottleneck, only tail lights with "significant
defects" may be replaced until such a time as more spare parts are available from the supplier.

•

See Differentiation section for examples of "slight" and "significant" defects.

•

This Quick Information will be updated accordingly when the supply situation changes.
