V Class central locking

[MichaelL]

I've recently bought a V class 230 and the central locking dosn't work. I've replaced the control unit with one from a breaker's yard but that didn't help at all. Also, the unit 'ticks' continuously, ignition on or not, as if a relay is being activated. Does anyone have any idea where I can start looking?

The V Class has a certain reputation. If you have bought from a dealer get an independent assessor to go over it thoroughly, and log every single item that goes wrong.
