Disadvantages of the EP6FADTX engine
- On specialized forums, there are complaints only about replacing the wiring harness and fuel pump under warranty.
- Due to the aggressive operation of the Start-Stop system, the chain can stretch up to 100,000 km.
- The fuel injection here is only direct and the intake valves are quickly overgrown with soot.
- Other engine problems are related to electrical failures and are treated with firmware.
