1.4 MultiAir Actuator Failure

The 2016 launch of the Fiat 124 Spider resurrected a classic nameplate, pairing a stylish Italian body and a turbocharged engine with the superb chassis of the Mazda MX-5. It offered a distinct, more relaxed touring character compared to its Japanese sibling.
The "MultiAir" brick can fail if oil changes are missed or the wrong viscosity is used. This is a common and expensive failure.
With production ceased and the Mazda-Fiat partnership ended, 124 Spider-specific parts are becoming scarce and expensive. Body panels (especially aluminium items), windscreens, key fobs and even the bonnet pedestrian-safety actuators can be on backorder for months. Some cars have been written off due to parts being unavailable for minor accident repairs.
If the 1.4 MultiAir engine sits unused for several months, oil can drain from the hydraulic MultiAir unit ("the brick"), affecting the valve train and preventing the engine from starting due to lack of compression. The fix is usually to crank it until the unit re-primes, but repeated occurrences can damage the unit.
