Disadvantages of the Hyundai D4FE engine
- So far, the main complaints on specialized forums are caused by the vagaries of the engine fuel system;
- The presence of an SCR catalyst implies the use of an AdBlue urea solution;
- As always, a lot of trouble here is associated with a particulate filter, as well as an EGR valve.
Some of the problems are related with oil pump belt wearing out prematurely and clogging smaller oil canals of oil-vacuum tandem pump, reducing oil pressure to 0 ~ at even 80000 km-s. Some of the problems are related to condensation in the intercooler (usually in -5 to + 5 degrees weather, resulting in worst cases, hydrolocking of the engine. Some of the problems are related to low-pressure EGR system sieve filter clogging up even at ~30000 km.
