The factory remote central locking on my pre-facelift B5 packed up yesterday. Got to work and pressed the button on the keyfob, only to find that the indicators flashed and the door LED pins began winking but none of he doors locked. Checked out the pump in the boot, and each time the keyfob is pressed to lock/unlock the car there is just a quiet 'click' sound from the pump but no whirring as if its trying to generate pressure? Can anyone help me diagnose if I have the dreaded shattered pump impeller syndrome? Having searched and read a load of threads on here about the pumps packing up they all mention that the pump should be noisy just no vacuum is generated as the graphite impeller is broken.......this is what is confusing me as mine is silent,apart from the electrical clicking noise..... The other odd thing is now when getting into the car from unlocking the drivers door manually with the key the interior lights go off straight away on closing the door, whereas before there was the 30 second courtesy delay? I'm puzzled why this should be happening , but these 2 events are obviously linked...... Would be very grateful for any help. Thanks!
