Volkswagen Golf Mk7 Service & Repair Manual: Safety precautions when painting natural gas-powered vehicles

DANGER! Excessively high drying temperatures endanger life on natural gas-powered Volkswagen Golf Mk7 models — high heat increases tank pressure and can cause the gas tank to fail. This page gives the required temperature limits.

  DANGER!
Excessively high drying temperatures endanger life! High temperatures increase the pressure in the tank for natural gas or liquefied petroleum gas. Excessive pressure can cause the tank for natural gas or liquefied petroleum gas to burst, causing severe injuries or death.
High temperatures trigger the thermal fuse of the cut-off valve on natural gas tanks. Increased pressure due to high temperatures triggers the pressure relief valve on liquefied gas tanks. Gas escapes from the tank for natural gas or liquefied gas and, in the presence of sparks, can produce a jet of flames. This may result in severe injuries or death.
  Never expose gas-conducting components to temperatures higher than +60°C.
  For drying in an oven above +60°, first remove all tanks for natural gas or liquefied gas and vent all gas lines.
  For infrared drying, never expose gas-conducting components of the high-pressure storage system to temperatures above +60°.
Observe safety precautions and other instructions when working on gas-powered vehicles (»LPG« or »CNG«):
Observe safety precautions → Fuel supply system – natural gas engines; Rep. gr.00
Remove fuel tank → Fuel supply system – natural gas engines; Rep. gr.20
