I am not too sure what your mechanic did mate. It certainly sounded like the circlip had detached itself from what you described. That would have been a 2 minute job to fix.
If it needs adjusting now as it seems, then your mechanic might have moved something there.The adjustment is on the rod leading from the base of the lever towards the front of the car.just near the steering rack. Loosen the bolt and make very minor adjustment in the splines until you get it right.
You can loosen the 10m/m bolts holding the gearleverassembly in place and maybe try moving that first?
