Hi Dave,yes it was an upright and lateral mounted,turbocharged preigniton chambered,Bosch mechanical injection system diesel engine,car was 1997 model.And unlike DieselDan I couldnt get anything on warranty because it was either 100.000 Km s or 1 year(which one gets early).And I was able to make only 18000 km s in one year.Then I swear never having any VW product since.The eggshape wear was not exactly on side but some cornered and all equal on 4 cylinders.
