any bro know what does tis error code mean?
I use an OBDII software to scan the car found this error:

PO657-- Actuator supply Voltage A Circuit/Open

and wat is actuator?

Hi, have you checked the wiring to the actuator from the ecu?
Also the actuator is the mechanical device for moving or controlling a mechanism. It will take in energy, usually via air or electric whcih if it is showing electrical fault lets just say electric and will put it into a motion for the car.
How is the car running, is it in limp mode, maybe you should get it tech 2 tested, get a ecu check as well, it might cost you a little bit, but its better to be safe then sorry
If I knoew where you was, I can more then liikely get these checks done for you for free, to spare you £100 or so mate.
Best of luck Izzy
