Have you managed to find a wiring diagram? Not sure if fuses are located in boot?I have an Audi A5 2012 Sportback 2.0 TDI, I need to tap into at least 10V to power a device that will be situated in the boot. I will already be sniffing the CAN Bus network in the boot. Is there somewhere located near the CANH and CANL wires?
To clarify though:
When you say "at least 10V" do you mean the device has a voltage range (10-14V for example?)
Can it be powered by 12V? In which case - splice into the 12V supply in boot (cig lighter)
And importantly - what is max current of the device? Need to check max current on line you've be attaching too or you'll blow fuses.
