WNQ2 - Checking Rear Lid and Reworking it if Necessary (Workshop Campaign)

Vehicle Type:

Taycan 4S (Y1A) / Taycan Turbo (Y1A) / Taycan Turbo S (Y1A)

Model Year:

2020

Concerns:

Rear lid

Cause:

On the affected vehicles, there is a possibility that clinch points were not attached to the rear
lid in the area of the rear spoiler in accordance with specifications during the production
process.
Over the service life of the vehicle, cracks can occur at the clinch points and lead to water leaking into the
rear lid/luggage compartment.

Action required: Check rear lid for leaks, and rework rear lid using body sealant if necessary.
Affected
Vehicles:

Only vehicles assigned to the campaign (see also PCSS Vehicle Information).

Required materials
Materials:

No parts and consumable material are required for the leak test on the rear lid (Scope 1).
Parts and consumables required for reworking the rear lid (Scope 2 or 3) (usually already available at
the Porsche dealer):
Part No.

Information
Use-by date and storage of body sealant

Expendable
Items:

•

After opening body sealant, store it in a dark, dry place at temperatures of 50° F to 77° F (+10° C to
+25° C).

•

Once the cartridge has been opened, changes can occur to the body sealant over time (e.g. a skin
can form). To prevent a skin from forming, seal the cartridge tightly after use.

•

If a cartridge that has already been opened and is still good to use is used at a later time for further
vehicles and a skin has formed or hardened in the nozzle in the interim period, a new nozzle must be
used.

•

It is up to the service technician to decide whether or not to allow repeated use of the body sealant.

•

If an open cartridge is past its use-by date, dispose of the entire cartridge and use a new cartridge.

•

Read and follow the safety and processing instructions for the body sealant.

The leak test involves blowing in compressed air. To do this, the compressed air must be set to max.
8 bar (116 psi) at the pressure reducer for the compressed air supply.

•

A second person is needed in order to carry out the leak test.

•

Do not use a high-pressure cleaner.

Work Procedure: 1

Clean rear lid at  Cleaning the rear lid -Marked areas- with isopropanol.

Cleaning the rear lid
2

Gradually coat the rear lid with the water emulsion, starting in the lower area of the cut-out for the tail
light and moving upwards.

3

Using a compressed-air gun or a compressed-air nozzle, apply compressed air to the inside of the
rear lid and re-spray it continuously with the water emulsion.
Guide the compressed-air gun in through the openings in the inner lid as far as possible towards the
sheetmetal flanges. Use a suitable extension if necessary.
Check the rear lid for leaks, starting at the lower area.
If there is a leak, you will see air bubbles.
Examine the outer area of the rear lid for signs of air bubbles.

Reworking rear lid
Information
Procedure for sealing

Area to be reworked (example shown at corners)
•

Before starting sealing work, mask or cover all adjacent areas, especially the exterior panelling.
Make sure that all residual moisture was removed completely before applying a new seal.

•

The surfaces to be sealed must be free of grease and dirt before applying body sealant. For this
purpose, clean all affected areas with cleaning solution and a lint-free cloth.

•

Apply body sealant directly on the paint surface.

Work Procedure: 1

Seal off affected areas with body sealant and rework with touch-up stick in vehicle color.
Information
Hardening body sealant
•

Leave body sealant to harden for approx. 4 to 5 hours at 20 °C and 50% relative humidity.
Longer hardening times will be necessary for dealers in dry climates. The hardening process
can be accelerated by increasing the humidity or by moistening the surface with water.

•

Press a finger nail gently into the hardened sealing compound (nail test). If this does not
damage the sealing compound surface, the sealing compound has hardened.
