However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT: Conform with SAFETY REGULATIONS !
Comply with instructions on handling AIRBAGS/RESTRAINT SYSTEMS and ELECTRICAL SYSTEM/ELECTRONICS .

1. General information

For repair cases the following procedure will implemented:
- Autogenous brazing solder
The MIG soldering procedure is not used in repairs for strength reasons. MIG soldered/brazed seams used in standard production are replaced during repairs by MAG weld seams.
Brazed areas from vehicle production are bonded following the same procedure.

2. Work materials

Tube pack and torch (autogenous torch)
Brazing solder
Gas bottles (oxygen and acetylene)
Welding goggles

3. Preparation

Remove the paint and zinc layer in an area of approx. 30 mm around the seam to be soldered.

4. Implementation

Execute brazed seam without overheating the solder and with low heat dissipation. If necessary, use heat protecting paste.

5. Subsequent treatment of brazed connections

Remove burnt residual zinc completely. Align and grind visible connection faces.
Remove burnt paint with a stainless steel wire brush.

6. Notes on melting/tinning

Only applicable within the European Union!

European used-vehicle regulations prohibit the use of tin containing lead in motor vehicles introduced after 01.07.2003!

Even out unevenness smaller than 2 mm with filler according to painting handbook

If an exceptional unevenness is larger than 2 mm, use METAL FILLER .

Only perform in visible areas of the outer skin and on the carrier support.

All areas which have covers on the vehicle are not to be processed.
