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 15°C) 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 → Rep. gr.00; Tools.

Removing

NOTICE

Risk of damage from overtensioning

– Do not overtighten tensioning straps.

– In areas shown, tension tensioning straps -2- transversely over roof to vary height of roof.

– Check dimension -a- on roof to roof side members.

♦ Dimension -a-= 6.0 mm ± 0.5 mm

– Fix position of new part -1- on front roof cross member and rear roof cross member using mole grips.

– If necessary, place felt strips underneath for compensation.

– Excessive 2-component body adhesive must be removed immediately.

– Weld in new part -1- (RP spot weld seam).

– Remove surplus 2-component body adhesive -4- immediately.

– Apply a thin coat of adhesive sealant onto seam between new part -1- and roof side member -5- to form a fine seam seal -2-.

– Adhesive bead -3- must seal off the interior.
