Is the 1.4/1.6 VTi reliable?

The 1.4 VTi and 1.6 VTi are the naturally aspirated versions of the Prince family, developed by PSA together with BMW and also used by MINI. They do not have a reputation for particular reliability: fiches-auto.fr documents frequent oil consumption in both displacements and a fragile water pump, later inherited by the turbocharged 1.6 THP; according to a German garage, the timing chain can also wear in any version, although the most reported cases are on the turbo engine.[1][2][3]

Is the 1.2 16v reliable?

The 1.2 16v (D4F) and its 8-valve predecessor, the D7F, are simple naturally aspirated engines, used for over two decades as the entry-level option in Renault and Dacia cars, with a reputation for reliability: the reliability pages consulted document no catastrophic failures and no oil consumption. The most-cited problems are ignition coils and sensors and, on higher-mileage cars, the head gasket.[4][5][6][7]
