Re: 1997 A6 - central locking

Hi Mark,

I have a similar problem with my 96 S6. The vacuum pump is located under the rear passenger next to the battery on the outside, wrapped in foam - it isn't fixed down to anything. Can you here the control unit attempting to activate the pump but there is no sound or action after the control is depressed - either from the remote or the switch on the driver door?

The control unit/pump part number is 4A0 862 257G (or J) for the unit with infra red remotes and 8L0 862 257B if you have a RF control unit. A new unit is approx US$380. Easy do-it-yourself fix, but when dismantling the middle connector must be removed first and replaced last when re-assembling - Bently repair CD says so.

Good luck,

Tony Ottawa
