Repair difficulty

Estimated cost

Affected models and engines

  • Volkswagen Golf, Passat, Tiguan, Touran and other 2.0 TDI models

Symptoms

  • Slap-modus
  • DPF-waarschuwing
  • Rook
  • Poor boost response

Why it fails

  • Short trips, failed sensors, intake leaks, and EGR deposits raise soot load.
  • Forced regens can hide root causes temporarily.
  • Illegal deletes create inspection and resale risk.

Checks before buying

  • Scan soot load and regeneration data.
  • Ask about commute pattern.
  • Inspect for DPF/EGR delete signs.
  • Check boost leaks and thermostat temperature.

Fault codes to investigate

Fault codes guide diagnosis; they do not confirm a part without live data, inspection, service history, and repeat testing.
