Here is a start: check the fuel lines for air, check the injection pump timing (use the timing belt article to find TDC and check the pump timing from there) when was the fuel filter last changed?


Possible Symptoms

  • Loss of Power at high Engine Speeds
  • Engine difficult to Start
Possible Causes

  • Start of Injection Timing Regulation not OK
  • Injection Pump Control Range blocked/dirty (e.g. by Metal Particles)
  • Engine has stalled / ran out of Fuel recently
  • Wiring/Connectors from/to Injection Valve (N108) faulty
Possible Solutions

  • Check/Adjust Injection Start
  • Check Fuel Supply
  • Check/Replace Fuse(s)
  • Check/Repair Wiring/Connectors from/to Injection Valve (N108)
