SITUATION

Note: Please see attached video V41 02 22.

CAUSE
Movement of the sheet metal layers at the Bpillar(s).

CORRECTION
Slightly bend the sheet metal layer at the top of the B-pillar.

PROCEDURE
Verify that a cracking sound from the B-Pillar is heard. If yes, identify left/right or both, then proceed to step 1.

3. Starting from the center line you have drawn,
draw another line vertically upward (17mm in
length).

4. The top end of the vertical line, defines the
exact position of the rework.

5. Using a weld spot drill bit, drill a hole with a
diameter of 6-8mm through the first three sheet
metal layers.

6. Measure the depth of the bore hole to ensure
that all three sheet metal layers have been drilled
through correctly.
Note: The rework might not be
effective if the bore hole is not deep
enough.
Drilling the bore hole to deep might
weaken the structure excessively
(should be avoided).

7. Seal the hole using MIG/MAG (metal inert
gas/metal active gas) process. To ensure proper
welding connection, the paint and corrosion
protection around the drilled hole must be
carefully sanded off.
Note: Make sure that all four sheet
metal layers are completely connected
before welding.

8. Clean and grind the welding surface to
create a flat, smooth, and burr free surface.
Then seal the entire area again with corrosion
protection and paint

Note: The paint protection applied to
this area does not have to be an
exterior quality finish.

9. Reassemble the vehicle and verify the repair.
