Common Problems with the
2003 Toyota Avensis Mk2 (T25)

The T25 Avensis arrived with a more modern design and improved refinement over the T22. The 1.8 and 2.0 petrol engines were the safe choices, while the 2.0 D-4D diesel offered good economy for motorway drivers. Build quality was typical Toyota — solid and well-assembled — though the seeds of the 2.2 diesel problems were being sown in later years.

What changed for 2003

  • •Complete redesign with more rounded styling and improved aerodynamics
  • •Introduction of the 2.0 D-4D diesel engine as the volume seller
