Fault in the waste trap causes source pressure test fails - WKB49439

Article number: 49439

SYMPTOMS

  • The source pressure test fails on a TQS micro
  • The system reaches +200mBar shortly after the test starts
  • An exhaust problem warning is triggered
  • The source pressure test fails after opening and closing the source enclosure
  • A new source enclosure O-ring does not resolve the issue

ENVIRONMENT

  • Xevo TQ-MS
  • Xevo TQ-S

CAUSE

A fault in the waste trap bottle assembly caused the exhaust solenoid valve to permanently shut, causing a blockage in the source exhaust system and resulting in the high pressures observed with gases on.

FIX or WORKAROUND

Replace the Bottle Waste Trap Assembly (700004606).
