Engine Overview and Common Failures
The weight of the R9M engine according to the catalog is 177 kg. The engine number R9M is located at the junction of the block and the cylinder head. Typical diesel problems. The most common complaints from owners to the service are related to the temperamental nature of piezo injectors, fast clogging of the EGR valve, of which there are two here, as well as the soot filter. Bearing rotation. There are many cases of bearing rotation at 150,000 km described on foreign forums, but this only applies to the engine modification with two turbos and a power of 160 hp. Timing chain stretching. The camshaft mechanism here is chain-driven and designed for the entire engine's service life. However, forums have many reviews about chain stretching even before 150,000 km. Smell of smoke in the cabin. On some Renault models, the heat exchanger in the EGR system often fails. It simply stops letting exhaust gases pass through, and they then seep into the cabin. Recall campaign. A recall campaign was conducted for diesel engines with twin turbocharging to replace the exhaust gas outlet tube on the EGR valve, which sometimes cracked here. Other weak points. Oil leaks from under the timing chain cover or oil filter housing are often encountered.
