Re: 166 central locking gremlins
Try plipping whilst watching all the door pins - 1 will be staying up.
If you use the key in that lock, the locking will work all around, then plip to alarm. To unlock, use the key, then plip to disable alarm.
This happened to mine last year - needed new passenger side lock as the electric bits inside had failed.
Some people have been lucky enough to take the lock out, clean it up and put it back & it works (IIRC)
Bulb light is usually reliable - mine comes on occasionally and I find a loose bulb - usually a sidelight in headlight - wiggle it & all OK.
