Yes I have, but with a GLX VR6 cluster. There is an issue of a change in warning light circuitry configuration in, IIRC, '96, so a later MY cluster should be used.

The conversion is very similar to the B4 but A3s are missing some additional wires & harness connector pins that must be added.

Missing cluster & relay panel connector pins & wires between cluster and relay panel:
  • Cluster pin 6 - MFA controller switch - goes to pin 8 of the U2 connector on relay panel.
  • Cluster pin 15 - MFA controller switch - goes to pin 4 of the U2 connector on relay panel.
  • Cluster pin 17 - oil temp. sensor - goes to pin 1 of the U1 connector on relay panel.
  • Cluster pin 19 - outside air temp. sensor - goes to pin 2 of the U1 connector on relay panel.
  • Cluster pin 1 - outside air temp. sensor - goes to pin 7 of the U1 connector on relay panel.
Missing cluster and ECM connector pins & wire between cluster and ECM:
  • Cluster pin 26 - Fuel consumption signal - which connects to ECM pin 9. This wire goes directly from cluster to ECM without passing through the relay panel.
Note that the above list does NOT include the missing 4-wire harness that runs between the MFA controller switch and relay panel.
