I'm almost certain the connections are good. I've swapped from the FDD cable to crimp lugs and the nothings changed. I've tried 2 different power supplies and the one i'm using has next to no ripple and plenty of capacity (2A). I connected up in the car and it took a 3 send attempts (through OSE tool) but in the end I got a reply of "F2,9E,1,0,79,0,0,0,B0,0,0,40,1,7,7,1,A4,3,1D,0,0,0,0,3,FF,1, 62,15,16,8,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,2,85,0,40,0,0,0,0,0,0,40, 0,FF,50,0,2,94,9,6B,F,FA,D,71,20,0,93"
The software and cable reset the airbag light in the VT no problem this morning.
I agree that spamming the bus isn't a good idea! so far I have found these device id's from delcohacking, here, ls1gto and the like:

Yeah, I have to admit that simulating modules isn't very useful... but I would enjoy moving a slider on the pc and watching the speedo show 240Km/H!
I have a spare 3 window (Berlina) VT cluster that i'm happy to throw frames at and see what happens. Just let me know what to send. I dont think the radio sends anything to cluster in the VT's. I pulled out the stock radio years ago so I cant log it unfortunately.
