Known issues
Most frequent / serious themes first; amber labels mark year gates.
Typical diesel problems
Often reported
Most common service visits are related to fuel system malfunctions, rapid clogging of the EGR valve (there are two of them), and the diesel particulate filter.
Cracks in the block
Heavier after 2019
The most well-known problem is cracks in the cylinder block; many owners replaced it under warranty. A reinforced block appeared only in 2019.
Timing chain stretch
Often reported
The valvetrain uses a chain designed for the engine's lifetime. However, many forum reports mention chain stretch before 150,000 km.
Burning smell in cabin
Often reported
On some Renault models, the heat exchanger in the EGR system often fails, blocking exhaust gases which then leak into the cabin.
Recall campaign
Often reported
For diesel engines with twin turbocharging, a recall was conducted to replace the exhaust gas recirculation pipe on the EGR valve, which sometimes cracked.
Other weak points
Often reported
Oil leaks from under the timing chain cover or oil filter housing are common.
