Can someone please give me some advice. My citroen c3 senso drive is semi automatic. I can turn on the car so the engine is running, but it won't go up and down gears and there's no power at all if u put your foot on the accelerator.

There's also a snowflake on the dash.

Welcome to the forum bexbickles

Snowflake/sport or snowflake/s indicates a fault detected with the gearbox. You will need to read the code to help identify where the problem lies. Use the Citroen Lexia/Diagbox (this thing) to read the codes in the gearbox ECU.

Our lexia topic is here, if you wanted to learn a bit more about it.


You can also use the Lexia to diagnose any engine faults that may be causing the 'no revs' problem, but reading the whole system will give you all the faults to then diagnose and fix.

With the lexia system I mention above, you get a full description and usually some suggestions on other checks or tests to carry out to help diagnose the fault.

The generic (not citroen specific) description is "GENERIC; Shift Solenoid A Malfunction" which would translate to one of the solenoids that operates the clutch or gear selection is not operating correctly. This could be caused by a faulty solenoid, faulty gear box ECU that drives the solenoid or the wiring and plugs/sockets between the gear box ECU and one of the solenoids.


P0750 also appears in these topics
