What age is your A6? The Concert2 expects a number of its signals via
the CAN Bus, including lights on, ignition on. There is no separate
connection for the lighting signal.
The A6, prior to 2002 MY would not have all the necessary signals on CAN
Bus - the only option would be to fit a CAN Bus simulator (often found
for sale on Ebay).
