Disadvantages of the FYDA/FYDB/FYDC engine
- The power unit is quite demanding on fuel quality;
- Due to poor fuel, spark plugs and individual ignition coils quickly fail here;
- The cause of periodic traction failures is most often in the fuel pump or its filters;
- The timing belt resource is usually less than 100,000 km, and when it breaks, the valve bends;
- There are no hydraulic lifters here, so you need to adjust the valves every 90,000 km.
