1.2 16v vs 1.2 12V: which engine is more reliable?
According to our risk index, the 1.2 16v carries less risk than the 1.2 12V: 36/100 (moderate risk) versus 57/100 (high risk). The 1.2 16v has 1 documented serious fault, the main one being «Damaged head gasket and coolant loss»; the 1.2 12V has 2 documented serious faults, the main one being «Timing chain stretch and tensioner wear».
The index (0–100) weights the severity and frequency of the three most serious documented faults. How it is calculated
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.[1][2][3][4]
See the 5 of the 1.2 16v faultsIs the 1.2 12V reliable?
The 1.2 12V is a simple, low-power, naturally aspirated three-cylinder engine (54-70 hp), with two documented design faults: the timing chain tensioner, which can end up destroying the engine, and -on the Volkswagen Polo IV- a catalytic converter too close to the cylinder head that can burn the exhaust valves. Ignition coil failures are also common, and there are isolated cases of oil consumption and vibration.[5][6][7][8][9]
