Measures for maintaining long-term body protection
INFORMATION: After repair work, the standard corrosion-inhibiting coating should only be restored with the corrosion-inhibiting agents approved by the manufacturer. The following points must be observed for body repairs.
- Always apply welding primer to both sides of the welding flange when resistance spot welding.
- Prime repair areas from outside. Prime on both sides in the accessible areas.
- Seal all sheetmetal overlaps, sheetmetal edges, butt joints, weld seams etc. with body sealant.
- When replacing structurally bonded body parts, proceed according to the information in the respective repair instructions.
- Only apply body sealant to primed sheetmetal parts.
- Apply single-coat top coat paint to the inside of the outer sheetmetal shell before welding.
- Build up paint on bright sheetmetal panels.
- Repair or create standard undersealing by applying long-life undersealing material.
- Preserve cavities in the repair area with cavity preservation after applying a single-coat top coat.
- Check that the standard water drains (plugs) are functioning correctly or clean them after the cavity preservation material has dried.
Prerequisite for maintaining the long-life guarantee
All body repair work must be carried out correctly and according to the specific Porsche instructions for sheetmetal, paint and corrosion protection/preservation work. To prevent jeopardising the long-life guarantee, a Paint Condition Report is made out 2 years after delivery of the vehicle. This condition report is made out by every Official Porsche Centre and should be updated annually.
Electronic control units
INFORMATION: If electronic components, e.g. ABS control unit, have been removed for repair work and are then reused, they must be given a functional check after installation in accordance with the existing specifications provided.
Protection against overvoltage
To protect electronic control units from overvoltage during electric welding work, the following work regulations must be observed:
- When welding work is extensive, the electronic control units must be removed. Ensure that there are no electrically insulated parts between the earth connection and the welding point.
- Remove clamp from negative terminal of battery and cover negative terminal of battery.
- Connect the earth connection of the electric arc welding equipment as near as possible to the welding point on the part to be welded.
- Do not touch electronic control units or electric cables with the earth connection or the welding electrode.
Replacing control modules
The replacement of electronic control modules after an accident is necessary if at least one of the following conditions is met:
The housing is noticeably deformed or damaged.
The supporting surface or bracket is deformed (the unit shows no external damage).
The plug connection is damaged or corroded by moisture.
Functional checks on or self-diagnosis of the unit reveals the fault "Control module faulty".
