This specific problem only relates to vehicles that have CMOS logic gate inputs connected directly to '12V' power electronics.
I started debugging my software on the TSM2 board at 8am this morning. There are/were a few bugs to squish. It is progressing well and relays are switching on and off but once the Hazards button has been pressed all indicators flash even when the button is subsequently released! My Audi A3 had the same 'feature' but that was caused by the previous owner spilling a drink over the hazards button thus making the mechanism rather sticky!
I expect to post the first prototype to a willing guinea-pig this weekend.
