Snallbans Posted October 26 Posted October 26 Hi, I have an A8 D2 circa 2001. It was originally fitted with Vacuum central locking and infra red remote. The central locking works fine, but the remote does not work. When I looked in the Trunk / Boot for the vacuum pump it was not where it should be. There was just a pipe and nothing else. As far as I can tell it still works through vacuum but where on earth have they moved the pump to. I have asked 2 garages to try and find it but to no avail, nobody has any idea where to begin the search. The garages are not Audi specialists and the car is old so I am asking the Forum where the most likely places are for someone to have moved the vacuum pump to. As the central locking still works it is in the car somewhere but I have no idea where to start looking. Any suggestions will be warmly welcome.
cliffcoggin Posted October 26 Posted October 26 What an intriguing puzzle. In my experience vacuum pumps are rarely silent so I would expect you to be able to hear it, even if the noise is no help in locating it. If you can not hear it I wonder if the car has been converted to electric locking.
Snallbans Posted October 27 Author Posted October 27 Thank you Cliff. I was thinking on similar lines but was unable to get a view of the driver's door lock. It is well hidden behind the steel frame. If I could access it there will be an electrical connection to either the vacuum pump or electric replacement where I could link the remote control to. I will attempt to see if I can hear some pump noise over the mechanical sounds.
cliffcoggin Posted October 27 Posted October 27 Another thought. You mentioned an open ended pipe in the boot. Does blowing or sucking on it produce any response at the locks? That should tell you if it is connected to anything.
Snallbans Posted October 28 Author Posted October 28 I will try it, but I suspect an open pipe would make the locks inoperable. Thanks for the idea.

It would if the locks are still vacuum operated and that pipe was still part of the vacuum circuit. However if you can easily pass air down the pipe without an effect on the locks then the pipe can be eliminated from further investigation. Edited October 28 by cliffcoggin omission 1
