• !! EGR cooler soot-clogged — fire risk from 60,000 km

  The D3/D4 VEA diesel had a defective EGR cooler gasket that formed soot paste from condensation. EGR pipes and cooler clogged up to 90%. Volvo issued a recall in 2020 due to fire risk. Dealers reported 5–10 repairs per week.

  Symptoms: Check engine light, engine throttling ('turtle mode'), EGR fault code, in severe cases smoke from engine bay

• !! Timing belt maintenance must be observed from 150,000 km

  The D3 Drive-E uses a timing belt with a change interval of approx. 108,000 miles / 10 years. Many used vehicles have no documented belt replacement. Belt failure means total engine damage.

  Symptoms: No warning before belt failure — engine stall. Belt check: look for cracking, wear, hardened rubber
