ZV, kaput? (F

[Lord of the Rings]

Dear Rasmus,

my Danish is a little too rusty, so I will answer in English.

A couple of possibilities come to my mind:

1. You mentioned that your car got a paint job done, could it be possible that it was exposed to high temperature for a longer period of time? I believe Audi allows for max 80° for a period of 90 minutes, otherwise the car needs to be stripped completely. If that is the case the vacuum pump (Bi-Druckpumpe) - which includes the electronic control of the power locks, as well - might got damaged.

2. Vacuum leak in the vacuum hose system.
The Vacuum pump - provided the system is in good working condition - shall lock all power locks within 2 seconds. If the pump operates for more than 5 seconds, then there is a leak in the system. If there is a leak, the pump shall operate for a maximum period of 30 seconds. Than the control unit shall stop the pump.

If the pumps operates for more than 5 seconds, you know there is a leak:
Locate the vacuum pump behind the rear cover on the passenger side and inspect the hose to the first T-divider. Remove one hose after another from the T-divider and close the opening at the T-divider with a finger and operate the vacuum pump in order to identify the leak. Continue with the remaining hoses and T-Dividers.

Unfortunately the vacuum pump cannot be repaired - some people in the board mentioned that they did anyways - and is pretty expensive ($380 CDN).

3. If the pump is working properly and there is no leak in the system, you should check all electrical connectors. All power locks have an electrical connection to the Bi-Druck-Pumpe. Therefore you need to uninstall the door panels, the trunk lid cover and the right trunk cover to get access to the trunk lock and the fuel lid lock.
Check with an Ohm-meter the connections and replace broken cables.

Please don't hesitate to post your findings and any additional question.

Good luck
Lord
