Porsche MA1 / 9A1 vs 1.2 12V: which engine is more reliable?
According to our risk index, the Porsche MA1 / 9A1 carries less risk than the 1.2 12V: 25/100 (moderate risk) versus 57/100 (high risk). The Porsche MA1 / 9A1 has 1 documented serious fault, the main one being «Bore scoring in the MA1 of the 997.2 and 987.2: uncommon, but documented»; 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 Porsche MA1 / 9A1 reliable?
Yes, it is noticeably more reliable than the M96/M97: it eliminated the intermediate shaft with its IMS bearing and, according to FCP Euro, the connecting rod bolt failures. What is documented is minor: carbon build-up on the intake valves caused by direct injection, coolant pump leaks on the 991.1 and, rarely, bore scoring on the 997.2.[1][2][3][4]
See the 3 of the Porsche MA1 / 9A1 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]
