Kia & Hyundai D4FE 1.6 CRDI MEHV Engines

 created this page to share my somewhat disappointing experience with the KIA D4FE engine and the fun I had repairing one which hopefully will help others.

The D4FE is a full aluminium Euro VI compliant replacement for the earlier D4FB engine which had been considered a very reliable power unit.

Unfortunately it appears that the group way have cut a few corners when developing this completely new engine and exasperated those issues when they decided to mate it to a Mild Hybrid (MHEV) system.
