2. Separating cut

• Parting cut can be combined with others in cases where extent of damage requires multiple cuts.

3.  Extended repair area

• If B-pillar reinforcement also has to be replaced, extended repair area must also be cut out when cutting out outer B-pillar.

4. Bonded area
5. Separating cut

• Parting cut can be combined with others in cases where extent of damage requires multiple cuts.

6. Separating cut

Renewing B-pillar

WARNING

Gases/vapours hazardous to health are generated when welding, soldering or cutting using tools which produce sparks in foam-treated areas.

• Do not weld, solder or cut closer than 15 mm to moulded foam inserts.
• Use an extraction system during work.

NOTICE

If separating cuts are made too deep, underlying reinforcement could be damaged.

• Only make separating cuts with body saw.
• Rewelding of reinforcements is not permitted due to safety reasons.

NOTICE

If welds are positioned too far on outside, strength could be impaired

• RP weld points must be placed as far as possible from outer edge of welding flange.

NOTICE

If adhesive is applied prematurely, bond could be impaired

• New part must be welded in within 90 minutes.

NOTICE

Bonding properties of adhesive may be impaired if adhesive components are not hardened sufficiently.

• After bonding, the vehicle must not be moved and left at room temperature (at least 15ºC) for 8 to 10 hours.
• During this time, the vehicle must be standing on a level surface.

Observe safety information ⇒ Rep. gr. 00; Safety information Only tools and workshop equipment authorised by Volkswagen AG may be used ⇒ 2.1

Removal and installation are described for left side of vehicle as an example.

Removing

• Make parting cut -2-, -3- and -4- in a straight line, as shown in illustration.

• Separate original joint.
• Detach B-pillar -1-.
• Remove any foam residue -1-.

• Remove remaining material.
• Completely remove remaining adhesive.
• Grind bonding surfaces and welding surfaces back to bare metal and clean.

Installing

Replacement parts

• For allocation of moulded foam inserts, see ⇒ Electronic parts catalogue (ETKA)
• For allocation of 2-pack body adhesive, see ⇒ Electronic parts catalogue (ETKA)

Important

• New parts must be adapted and attached with the vehicle standing on its wheels or straightening bracket set.
• Transfer separating cut -2- to new part -1-, and cut in a straight line.

• Grind welding surfaces and bonding surfaces on new part -1- down to bare metal and clean.
• Prepare moulded foam inserts -1- for installation and insert.

• Apply 2-component body adhesive to entire surface.
• Adapt new part -1- to fit and fix in position.

• Check fit with add-on parts.
• Fix new part in position -1- with mole grips.
• Weld in new part -1-, RP spot weld seam.
• Weld parting cuts (either MIG solder seam or SG stepped weld seam).
• Weld extended repair area -2- if necessary (MIG solder seam or SG stepped weld seam).

Vehicles with type plate.

• Reattach type plate after painting ⇒ p3.1.2 late"

Vehicles with safety certificate.

• Reattach safety certificate after painting ⇒ c3.1.3 ertificate"
