Engine Overview and Common Failures
The dry weight of the EXF engine according to the catalog is 220 kg. The engine number EXF is located on the cylinder block. The most common problem with this engine is the crankshaft breaking at low mileage. There are many hypotheses, but it seems to be a defect, as most diesel engines last up to 500,000 km. The second most common issue is frequent leaks from the oil cooler, which is quite expensive to replace. The fuel injection pump (TNVD) fails quickly due to poor quality fuel, causing metal shavings to be generated immediately. The EGR valve also does not have a long lifespan, and when it breaks, the RPM fluctuates. The hoses and pipes are also weak points of the engine, often getting punctured or leaking. Furthermore, there was a recall campaign to replace defective cylinder heads due to vibrations.
