Disadvantages of the M15A-FKS engine
- The presence of direct injection D-4 implies demanding fuel quality;
- So far, on specialized forums, they often complain only about leaks in the EGR liquid cooler;
- Sometimes this heat exchanger cracks and antifreeze gets directly into the engine cylinders;
- Closer to 100 thousand km, the EGR valve is often clogged with deposits and completely wedges.
