Volkswagen Golf Service & Repair Manual: Contact corrosion

elements (screws, bolts, nuts, washers, etc.) are used. |

adhesives made of electrically non-conductive materials. |
| If there is any doubt about the suitability of parts, a

lines/wires/cables/hoses/pipe are all installed in their

before they are removed. If necessary, take a photo or make a

| Because of the lack of space in the engine compartment, make
sure that all lines are sufficiently far away from all moving or
hot components. |

only because of such minor dents. |
