Thanks to all. I got to drive it back earlier today.
After running the car for 15 mins, I switched it off, put it in gear, released the handbreak then vigorously rocked the car back and forth. Did the trick. Thank you!
I managed to drive it home, however I need to fix the gearbox. It’s difficult to put in gear and once it’s in gear it clicks continuously unless I hold the gear lever in a certain position. May need to find a helpful local mechanic to take a look.
Thanks again to each of you for helping to get me up and running again.
