Having read the various threads on fixing W123 central locking, I've decided to have a go at fixing the lack of vacuum in my Merc and fallen at the first hurdle. Can someone tell me if the pic below is what I should be testing?
Do I pull the tubes off to check the vacuum, and are they just a push fit back on?
The piston in the unit has no resistance at all whether the engine is running or not. Does this suggest it's faulty?
Any suggestions gratefully received!
