Warnings
MANDATORY TO REPLACE OIL, OIL FILTER AND GASKETS
In case of an issue, without proof of the replacement of ALL parts, the warranty may be void..
In case of warranty, if contaminated oil is found inside the actuator, we cannot process it without the certification of the filter change via purchase invoice.
WARNING: please pack the carcass that we request back with utmost care,
preferably using the same packaging and care with which we send you the ordered spare part.
If the carcass arrives damaged, THE DEPOSIT WILL NOT BE REFUNDED.

Techinical Info
The OE MultiAir module 46339031è an electro-hydraulic actuator designed to control the’variable lift of the intake valves in gasoline engines. In the FireFly Turbo 3 cylinder 1.0 T3 of the FCA/Stellantis group (displacement 999 cc), introduced in Europe starting from 2018, this system allows precise control of the’intake for each cylinder, optimizing consumption, performance, and emissions. The module è installed directly on the cylinder head, operates thanks to engine oil pressure and è is electronically regulated by the ECU control unit.
Potential anomalies
Clogging of the hydraulic circuit
Contaminated oil or irregular oil changes lead to the occlusion of microchannels. This causes delays in’valve opening, jerking, and irregular performance.
Internal mechanical wear
With prolonged use (over 100.000 km), pistons, valves, and springs may fail, generating abnormal play and loss of pressure.
Solenoid failure
The electrical/hydraulic blockage of the solenoids causes the cylinder to malfunction. The engine runs on 2 cylinders, the warning light comes on, and the idle becomes irregular.
Electrical problems
Insufficient voltage, a dead battery, or oxidized wiring can compromise actuation. Loose connectors are also a frequent cause.
Oil leaks from seals
O-rings and internal seals can degrade, causing leaks that compromise hydraulic pressure and increase oil consumption.
Recognizable symptoms
- Check engine light (MIL) on
- Running on 2 cylinders
- Stuttering while driving
- High consumption
- Unusual noises when cold
- Recovery mode active
Typical defects
Failure to ignite one or moreù cylinders
The vehicle does not start
Engine control system malfunction indicator light on
Error Codes

TSB and software updates
TSB 10.009.21 (Fiat 500X / Tipo / Jeep Renegade): reports issues with the check engine light and DTC codes related to MultiAir. The manufacturer plans a software update for the ECU to optimize module management.
