I think I just stumbled across a gem!

This guy has a blog (with a lot of great articles) on his D3 A8L which happens to share a ton of things with our C6s, especially the MMI 2G.

It seems that he has found a way to get rid of the cold diagnostics. I haven't tested it, but based on my understanding of the reading, this will get rid of LED errors (which I don't have) as well as the cold diagnostic flashes (which I DO have).

It comes down to adding a PTC on the circuit in parallel to a resistor. The resistor takes car of the 'hot' bulb out warnings and the PTC kills off the cold diagnostic flashes.
