Hi, I wonder if someone could help me, my daughters corsa developed the flashing F a few months ago, we managed to keep it working for a while by disconnecting and reconnecting the 2 plugs to the ecu, then that stopped working and we had to gentley tap the gear actuator to get the car to go into Neutral to get the car to start. We then decided it was a problem with the ecu, so we sent it away to be repaired, when it came back it was refitted and the clutch was bled twice, the car now starts but still has the flashing f and will not go into gear at all, so then we decided to buy an opcom obd2 which is comming up with P1700 which clears and P1723 which doesn't......have changed the gear selector motors and still the same problem, starts....no gears and a flashing F....any help would be much appreciated....need to be mobile again!

Many thanks in advance.
