2 faults documented by at least two sources, listed by version then by mileage at onset when known.
2 known faults
On the 1.3 VCDi, the diesel particulate filter and the EGR valve are cited as the main sources of problems, especially in urban use (CarVerif, Car Reliability Report). Icarsoft also reports EGR clogging on Aveo diesels. Mainly motorway use limits the risk.
Fiches-Auto ranks the cylinder head gasket as the most reported fault on the 1.3 VCDi 95 hp, based on a very small sample (11 reviews). A Caradisiac forum thread links cylinder head removals on this 1.3 to valves clogged by EGR deposits. To be checked (oil in the coolant, overheating) before buying.
