Any device that blocks the Infotainment CAN bus can cause the on/off message to be blocked, so it's worth checking all the dvices on the Infotainment CAN bus.merlinus98 wrote:I had this kind of problem, due to a faulty iPod or bluetoth adapter that sometime cut the CAN bus: my RNS-E didn't turn on/off automatically, if I turned on manually, it stopped itself after 30mn, stay on even 5mn after I stop and lock the car (and anything else stopped) !PetrolDave wrote:...
then the first thing to check is if the RNS-E has any CAN bus fault codes (it's a CAN bus message that tells the RNS-E to turn off).
The RNS-E turns on when you UNLOCK the car, and stays on until either 30 minutes after you turn the igniton off or you LOCK the car (whichever happens first)...
And my battery had a big drain...
iPod adapter unmounted, bluetooth rewired, original battery (5 years old) changed: all is ok
The other thing that has been known to cause it is a faulty version of the Audi Bluetooth module (version L IIRC), but that's an EU only version should probably isn't the problem that 07misanored has.
