Do you by any chance know which fault codes qualify? I'm trying to find out...no luck so far.

My understanding is that the "new software" solution was for early SBC units that had a lower actuation count threshold. I'm sure my 06 already has the higher threshold.

I would assume it's at least the following:

C249F Operating time of a7/3 (hydraulic unit) is exceeded
C2131 Pressure Reservoir faulty
C235C or C235A Service threshold reached

My local service adviser was singularly unhelpful. "Would just have to bring it in for diagnosis...the codes are proprietary information...yada yada yada..."
