BMW X5: Corrosion Protection

NOTE: Following repairs, the corrosion protection work already begins with the correct removal of the PVC undercoating, antinoise compound and seam seals.

1.0 Removing sealing materials:

IMPORTANT:

Remove PVC material with a rotating steel brush, or heat PVC to maximum 180ºC with a hot air blower and scrape off with a spatula.

2.0 Corrosion protection of sheet-metal parts:

All weld joints sealed off with body sealing compound in original state must be primed and sealed off again thoroughly after repairing. Replace damaged or removed antinoise compounds.

NOTE: Spray gun required for body sealing compound (order no. 81 49 0 300 887).

Concluding cavity protection is the most important part of all corrosion protection measures.

Use the cavity protection spray only for smaller-scale straightening work where the parts in question are easily accessible. Use the HRS spray gun with pressure container for all other repairs. Cavity protection agent is available in different container sizes.

Use the relevant probes with tubes for the different cavity areas.

Required tools are featured on the WORKSHOP EQUIPMENT PLANNING CD (WEP).

IMPORTANT: Incorrectly performed cavity protection can, especially in the case of steel/aluminum joints, give rise to a non-calculable product liability and safety risk.

The best repair is worth nothing if the subsequent cavity protection measures are not conscientiously carried out.

2.1 Cavity protection of steel parts:

New doors and lids must be sealed with cavity protection agent after being painted.

New sheet-metal parts or cavities, weld seams and folds formed by new sheet-metal parts must be sealed with cavity protection agent after being painted.

The cavities affected must be sealed with cavity protection agent after all straightening work.

2.2 Cavity protection of aluminum parts:

New doors, lids and side panels made of aluminum are not sealed with cavity protection agent.

After all straightening work on aluminum components, the cavities affected must be sealed with cavity protection agent after being painted.

After all welding work (E52 only) on aluminum components, the cavities affected must be sealed with cavity protection agent after being painted.

Cavities, seams and folds formed from new sheet-metal parts must be sealed with cavity protection agent after being painted.
