Is the 1.6 dCi reliable?

The 1.6 dCi (R9M) is a diesel with a generally reasonable track record, but with well-documented known faults: the turbo fails relatively often, even at low mileage, the EGR valve clogs, the particulate filter can block up on short journeys, and there are cases of oil leaks from the timing chain cover that go as far as requiring the engine to be removed.^[1][2][3][4]

Is the D5 5 cilindros reliable?

Volvo's five-cylinder D5 (2.4 D3/D4/D5 and 2.0 D3/D4) has no documented systemic fault, but it does carry one serious risk: several owners report that a snapped auxiliary belt took the timing belt with it. The rest is EGR, DPF and the odd turbo.^[5][6][7]
