Kishorelal Deva came across this procedure some time ago.
- Start the car with the foot on the brake.
- Put it in first and then back into neutral wait 5 sec.
- Repeat the procedure 10 times and then switch off the car.
- The gear "creep" should now be adjusted.
This might explain how they manage the auto adjustment as the clutch plate wears in normal use. Not been proven but may well work.
