The central locking system in the 123 is operated by engine vacuum and
is very sensitive to even slight leaks (that are often modulated by
temperature/humidity). Most common presenting symptom is that the engine
shuts off slowly or doesn't shut off - and that may change if the car is
locked or unlocked. Not difficult to troubleshoot with vacuum diagrams

a MityVac and some golf tees. The 124/126/201 central locking systems
are powered by an electric vacuum pump and seem to fail FAR less often
(they may leak just as frequently, but small leaks simply are NOT a
problem). Engine vacuum is not involved, but the actual system is
otherwise rather similar.
