Hi. I used a tool called op-com.its a laptop obd2 diagnostic tool similler to tech2 wht the dealers use. Check ebay. Bc easy to program with it. I changed my bc code from 01 which is computer off to 02 which is computer on.
ok here is how to turn on the board computer using op-com, this works a treat for my antara which is the 2,4 petrol exclusive, select astra h 2010, go to infotainment, click on it, then click on dis board display tid,bid,gid.. you should now see a list of configs, click on the bottom one programing code index, a list of numbers appear, mine was set on first one 00103, board off, I clicked 00202 board on, then click program,, job done Vauxhall told me that the bc wont work on my exclusive
as grumps says it is limited on the antara, but it can do keys air bag, some bodycontrol things, it wont let you into the engine ecu, but I am sure it dose on one of the other lists as I have a seen all my engine displays but cant mind how I got it, will have a play around and post when I find it again, I bought one soley for programing the bc, as I read on other vx forums that this can be done shame on vx for not doing this at factory
