Disadvantages of the EP6FADTXD engine
Under warranty, some owners of the original engines changed the fuel pump and wiring harness.
The chain can extend up to 100,000 kilometers because of the Start-Stop system’s aggressive operation.
Here, the intake valves are rapidly covered in soot, and there is only direct fuel injection.
Flashing is used to address all other issues that are caused by electrical malfunctions.
