I have external ACC and ILLUM signals. So, I have a drain problem if I disconnect both CAN-wires permanently (I don't need the CAN, I don't have the buttons on wheel). After closing the car the drain is very high. And maybe your solution doesn't work on Tiguan'08 platform. I'm not sure, but without CAN my car doesn't sleep.Alex,
if you remove the radio from the devices installed in the car using VCDS cable then you won't be able to turn on the unit. That's not an option and even doing that the current drain goes down but not to the normal level.
Using a relay to interrupt CAN+ and CAN- will work but the only one needed to be interrupted is the CAN+. With that battery drain issue is gone.
Also if you want to have ACC signal (it may be implement for relay and for work of device in position 0 of key), you may buy PHONOCAR 5/143 adapter. Connect ACC signal to ACC wire through diode and in your solution to relay. You must get a working device in all three positions of key, with buttons and other, and no drain problem in your solution.
