On my 1988 320i Touring I cannot lock the car from the driver's door. The central locking locks from passenger side and tailgate. Central locking will unlock from the all the locks, including the driver's door. Anything quick I could try?

Try adjusting the lock motor - it has slotted mounting holes.
The real problem is wear/lack of lubrication in the linkage between the key barrel and the motor, with the L shaped bit on the back of the lock barrel usually being the main culprit.
