Any more progress on this Ajax?

I think I may have sourced an ACC capable cluster for my 2007 A6 so I'd love to know if it works... and what other parts might be needed (apart from radar head and wiring loom)

Where are the brake thrust sensors located that seem to need replacement?
 
I've found a ACC cluster but its £800!

Im thinking long and hard wether its worth the cash or not.

The rest of the install seems straightforward enough, just bloody expensive!
 
From the research I have done it seems that non-ACC clusters simply dont have the required firmware inside them to support the addition of ACC.

Mine is a late 07 and works in the same way as your 08 model. I dont think it will support ACC as the ACC option code (PR-8T4?) isnt listed next my cluster in ETKA,

It'd be nice if it did though as this would save me a fortune!
