When modules cannot be reached in a scan my default thought is to run an Optical Bus Diagnostic providing there isn't anther obvious reason.
The majority of the diagnostics I've done have been on C6 and D3 and later, so it's almost automatic for me.
Forgetting it's not ubiquitous, people respond "Uh... my car doesn't have that" when I've suggested running the procedure. <facepalm>
Is there a way to determine MOST presence in a vehicle without physically looking or checking erWin ?
The only pattern I've been able to determine is if Nav has an optical performance setting, and possibly the presence of 07 Control Head.
Appreciate any input.
