First things first Pete, we need pictures or the forfeit is a round of beers for all members (24,000 Budweiser's is quite pricey) Fault 12 is an air distribution flap or motor issue, from here

 

Thanks Kermit

Been very happy with my 9-5 wagon, bought new, just turned 61000, in 5 years.

The past year, though, there have been 4 tows to the dealer.... each time a chunk of change to the dealer. (I can only imagine the glee in the service writer's eyes when I tell them my ACC is throwing 3 error codes...)

So, I'm hoping that this ACC control issue is something I can tackle...

That said, the thing now is throwing 3 codes -- 10, 12, 13.... (seems to be getting worse)...

Who's good to contact to order parts?

Pete, get the trim off the side of the centre console and observe what flaps are moving and what aren't moving. Its usually a broken shaft or cam on the flap thats at fault ($10 part max). Dealers will charge the earth to fix so hang upside down like a bat in the footwell and DIY it yourself. Have a look at the FAQ's sticky to see what you are facing, its not too daunting once you know what you are dealing with. Parts suppliers are the usual culprits www.eeuroparts.com or www.genuinessab.com
