WARNING: This page is about a different car, the 1997 Volkswagen Passat. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ensure engine coolant temperature is at least 122°F (50°C). Start engine and allow it to idle. Disconnect vacuum hose from EGR valve. See Fig 1 . Connect hand-held vacuum pump to EGR valve and apply vacuum.
  2. Idle quality must deteriorate noticeably. If idle quality does not change, check EGR valve and exhaust manifold for plugging. Replace EGR valve if necessary. After repairs, erase DTC memory.
