Thanks for your help, appreciated.

Here's the 535 alarm box from a right hand drive 2003.


Note the [W] pin A23 connects to the DME at pin A3. That is the only connection I see directly to the DME.



I also noticed that D26 on the DME is marked as "Actuation" and connects to the DME Relay [85] through pin 4 of connector X2/3. Do you have power at the relay?

Are you positive that you have a working and matched set of DME + Alarm (Immobilizer) module + key fob transponder?
