WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2011 BMW 328xi, 2011 BMW 328i, 2010 BMW 335xi, 2010 BMW 335i, and 2010 BMW 328xi. However, it is still accessible from the selected car via links, so may be relevant.
- The following procedures are used for repairs:
- MAG welding (M etal A ctive G as welding)
- Resistance pressure spot welding (referred to in the following and in the repair instructions as spot welding).
- Take the number and location of weld spots and MAG weld seams from the separated part. Replace areas inaccessible to spot-welding tongs with MAG plug/spot welds at the same distance. Diameter of bores for plug/spot welds 8 mm.
- In the case of emissions extraction, observe a minimum distance of 30 cm for MAG welding during the welding process. Otherwise the inert gas would be drawn off.
- Follow the equipment manufacturer's instructions for use.
- The following procedures are used for repairs:
- Gas brazing
- Tinning
- The MIG soldering procedure is not used in repairs for strength reasons. MIG soldered/brazed seams used in series production are replaced in repairs by MAG weld seams.
- Areas brazed in vehicle production are joined during repairs with the same procedure.
- It is possible when straightening steel parts to correct irregularities smaller than 2 mm with filler.
If in exceptional cases the irregularities are in excess of 2 mm, these areas must be tinned.
Only visible areas of the outer skin and on the support carrier must be tinned.
All areas which have covers on the vehicle are not to be tinned.
NOTE: Only applicable within the European Union!European used-car regulations prohibit the use of tin containing lead in motor vehicles introduced after 01.07.2003!
